Everything you need to know before you buy

French brand Mavic makes some of the most popular bike wheels out
there. It doesn’t produce anything super-cheap, its road bike options
starting at £150 and going right through to over £2,000.

Apart from the cheapest Aksiums, Mavic’s road wheels come equipped with
tyres because the brand sees them working together as complete systems.

The range is large and could be somewhat confusing, so we’ll try to break
it down as logically as possible. To muddy the waters even more,
Mavic recently introduced Road UST, which is its take on Road
Tubeless. Road UST versions are gradually replacing  many of
Mavic's most popular wheels but there's still quite a lot of older
non-UST stock in retailers. The venerable, much-loved Open Pro rims
is available in a UST version.

Mavic has recently
announced an addition to the range in the Cosmic Ultimate UST
, an
all-carbon fibre wheelset aimed squarely at road racers, and
expanded the Road UST range, notably with a UST version of the
entry-level Aksium Elite wheel, and new, all-carbon
UST incarnations of the Cosmic Pro aero wheels.

Fact of the day: Mavic is actually an acronym coming from Manufacture
d'Articles Vélocipédiques Idoux et Chanel. Charles Idoux and Lucien Chanel
founded the company in 1890 to make mudguards.

Without further ado, here's the essential data on the full range, plus
links to the cheapest sources we've been able to find.

Road UST

Mavic Road UST cross-section

Mavic
Road UST
cross-section

As you can see from the listing, many of Mavic's clincher rims are now
Road UST, and conventional versions are gradually disappearing as shops
run out.

You can learn more about Road UST in our news story about the launch of
the system: Mavic
introduces Road UST tubeless system covering huge section of wheel range
.

The executive summary for Road UST is that the combination of rim and
tyre bead design makes it easier to get tyres on and off, and to seat
them, according to Mavic. A Road UST tyre on a Road UST rim will seat with
a standard floor pump with as little as 47psi.

However, only Mavic currently makes compatible wheels and tyres, which
are designed together so there’s tight control over production variances.
The Road UST standard is being approved by both ISO (International
Organization for Standardization) and ETRTO (European Tyre and Rim
Technical Organisation) working groups, so other manufacturers will be
able to make Road UST wheels and tyres when that process is complete.​

Endurance wheels

Aksium

aksium_logo.jpg

Aksiums
— no, they're not Aksia, Latin pedants — are Mavic’s entry level road
wheels, specced as original equipment on countless bikes. The 2019 models
have been lightened compared to their predecessors. Aksiums have 21mm high
pinned aluminium rims that were widened for the 2016 model to 17mm
internal width to better accommodate increasingly popular wide tyres.
Mavic reckons Aksiums are best suited to tyres from 25mm to 32mm.

2019 Mavic Aksium

Like the rest of the range, Aksiums are built with straight pull spokes
which the brand says are stronger than J-bend options, and they run on the
brand’s QRM sealed cartridge bearings. That keeps maintenance down to a
minimum. The hub bodies are aluminium while the axles and the freewheel
are steel.

Aksiums are reasonably light for the money (a claimed 845g front, 995g
rear) and we’ve found them to be quick and generally reliable. These are
good, solid all-rounders.

Check
out our Mavic Aksium review.

Mavic Aksium disc.jpeg

The Aksium Disc uses the same rims and bearings but
with either a Center Lock or six bolt disc hub, and more spokes: 24 front
and rear as opposed to 20 front and rear. The front hub is convertible
from a standard quick release to a 15mm thru-axle design.

2019 Mavic AKSIUM ELITE UST

The new Aksium Elite UST is the
cheapest Road UST wheelset Mavic offers. It's a bit lighter than the
standard Aksium pairing at a claimed 1,780g (825g front, 955g rear)
because Mavic welds the ends of the rim together, then machines the
sidewalls flat rather than pinning the joint. The rims are 19mm wide, in
keeping with the trend of rims getting wider to better support wider
tyres.

Unlike the other Aksiums, the Elite USTs come with Mavic’s excellent
Yksion Pro tyres, which are basically Hutchinson
Fusion 5 ElevenStorm
with a different label. That makes the Aksium
Elite USTs very competitive if you're thinking of going tubeless: wheels
and top-quality tyres for under £250. 

Buy if: You're looking for reliable training wheels that
aren't too expensive.

Ksyrium range

ksyrium_logo.jpg

Mavic’s Ksyrium wheels have gradually evolved since 1999, building up a
reputation for combining light weight with loads of strength. You might
see the cheaper models as workhorse wheels but the higher up the range you
go the higher the performance you get for your money.

Ksyrium

2019 Mavic Ksyrium UST

The lower priced models in the Ksyrium
family are made with box section aluminium rims, and Mavic appears to have
quietly replaced the basic Ksyrium with the tubeless-compatible Ksyrium
UST
; they’re 25mm high with recommended tyre sizes of 25mm to
32mm thanks to the 19mm wide rim. Mavic use the same QRM sealed cartridge
bearings as you get with the Aksiums, and Yksion Pro UST tyres come as
part of the package.

All the metal-rimmed Ksyriums now have rims made from Maxtal alloy
instead of the 6000 series aluminium used for the Aksiums, which probably
explains the reduction in weight between the old and new Ksyriums. Mavic
also mills away material from the rim, between the spokes, to save weight,
a process it dubs ISM 4D for Inter Spoke Milling, and er, we've no idea
what 4D is supposed to mean.

The claimed wheelset weight is 1,650g (755g front, 895g rear), which is
pretty light for this price, although it’s combining that with a bombproof
performance that makes this a popular choice.

2019 Mavic KSYRIUM UST DISC

The Ksyrium Disc UST is essentially the same wheel but
with disc hubs and four extra spokes per wheel. Disc-compatible wheels are
often substantially heavier than their rim-brake equivalents, but the
extra 40g here appears to be entirely down to the extra eight spokes.

Buy if: You're after something that's reasonably light
and very sturdy.

Ksyrium Elite UST

2018_mavic_ksyrium_elite_ust.jpg

The Ksyrium Elite UST is differently constructed from
the wheels lower in the Ksyrium hierarchy. Instead of passing through
holes in both inner and outer rim, the spoke nipples are screwed directly
into the rim. The spoke holes are pushed through the inside wall rather
than drilled, and the pushed up material is then threaded to allow the
nipple to be secured.

To make the Elites user serviceable, Mavic has installed steel double
sealed bearings that are fully adjustable, even chucking in the tool you
need to do it.

When we reviewed the original Ksyrium Elites we said, “Great mid-range
wheels for the all-rounder, as happy to race as they are to cruise, but
the tyres are average.” Well, that last bit's changed. Like all Mavic's
Road UST wheels destined for use on asphalt, the Ksyrium Elite USTs come
with Yksion Pro UST tyres and they're very good.

Read
our review of the Mavic Ksyrium Elite.

2018_mavic_ksyrium_elite_ust_disc.jpg

In 2017 Mavic added a disc-compatible version of the Ksyrium Elite;
that's now the Ksyrium Elite UST Disc.

The Ksyrium Elite UST Disc uses a similar rim to the
regular Ksyrium Elite UST with a disc-compatible hub. There are versions
to take six-bolt rotors or those with Shimano's Center Lock mount. They
weigh a claimed 770g and 900g for front and rear respectively and come
with Mavic's Yksion Pro UST tyres.

Buy if: You want solid all-rounders that are light
enough to race.

Ksyrium Pro

2018_mavic_ksyrium_pro_ust.jpg

The Ksyrium Pro UST is built with spokes made from
Zicral, an aluminium alloy, which Mavic says are stiffer, stronger and
lighter than traditional stainless steel spokes.

We’re getting down to some very light weights now; the Ksyrium Pro USTs
come in at a claimed 1,410g (590g front, 820g rear).

Buy if: You want a lightweight wheelset that doesn't
compromise on durability.

Ksyrium Pro UST Disc

2018_mavic_ksyrium_pro_ust_disc.jpg

The Ksyrium Pro UST Discs are, you won't be surprised
to learn, the disc-compatible version of the Ksyrium Pro USTs. The hubs on
the Ksyrium Pro Discs are compatible with the increasing number of axle
standards that are available for road disc. Standard quick release is
covered, as is QR15 at the front and 142x12 at the back.

Buy if: You're after light disc brake wheels for
endurance riding.

Ksyrium Pro Exalith

Ksyrium Pro Exalith.jpeg

Exalith is a technology that Mavic has been using on some of its
aluminium rims for a few years now. The combination of a chemical
treatment and a file-like texture that’s machined into the rim is claimed
to reduce braking distances by 18%. You have to use specific pads that are
supplied with the wheels.

The other advantage of Exalith is that it reduces rim wear. If you ride
in grotty conditions and find road crud rapidly chews through your rims,
these wheels are a solid choice. Mavic still hasn't yet produced a Road
UST version though.    

For 2017 the Ksyrium Pro Exalith got a new, wider ISM
4D rim — 17mm across instead of the previous 15mm. Claimed weight is
1,475g/pr which splits out as 630g for the front wheel and 845 g rear.

Buy if: Powerful braking is your first priority.

Ksyrium Pro Carbon SL

Ksyrium Pro Carbon SL.jpeg

These carbon-rimmed wheels are designed for climbing although a lot of
effort has been put into making the braking performance as good as
possible. What goes up must come down, after all.

When this wheel was first introduced Mavic gave it an alloy insert that
formed the bed and the hooks for the tyre bead. This was designed to
ensure an even fit for the tyre and to dissipate braking heat through the
structure of the wheel. However, this insert disappeared when Mavic
developed better carbon curing technology, called TgMax, which could
support high temperatures on the braking surface. This surface is also
laser finished.

There are four versions, with either clincher or tubular rims and with or
without mounts for disc brake rotors. The rim-braked Ksyrium Pro
Carbon SL USTs
weigh a claimed 1,445g (front 640g, rear 805g)
while the £1,899 disc-compatible version is 130g heavier.

The Pro Carbon SL Tubular is the lightest Ksyrium
wheelset at a claimed 1,190g (515g front, 675g rear). The tubular disc
version comes in at 1,320g (625g front, 695g rear)

Buy if: You want a superlight wheelset with a good
braking performance.

Allroad wheels

2018_mavic_allroad_pro_ust_disc.jpg

For 2018 Mavic split out these beefed-up wheels from the main Ksyrium
range, although they still have a lot in common with Ksyriums, and for
2019 Mavic introduced two new models, the entry-level Allroad and the 650B
Allroad Elite Road+ Disc. They all have Road UST rims with 22mm internal
width for the 700C wheels and 25mm for the 650B. Mavic says they work with
28mm-62mm tyres.

Irritatingly, Mavic has already abandoned the naming convention
introduced with Road UST. The new Allroad is both Road UST-compatible and
disc-brake-only, while the Allroad Elite Road+ Disc has a Road UST rim.
That's not surprising, but while there are still older models in
retailers, a little consistency of naming would help customers know what's
what.

Allroad

2019 Mavic Allroad

The new Allroad — or Allroad Disc UST as it should be
called — is the entry-level dirt road wheel with a sleeve-joint rim in
S6000 aluminium, 24 steel spokes front and rear and a wide range of
compatibility with different dropout and quick-release standards. The
dirt-road equivalent of the Aksium, the Allroad doesn't come with tyres.
It's clearly intended as a wheelset for bike manufacturers to spec as
original equipment, replacing the previous non-UST Aksium Allroad.

Buy if: You want an inexpensive set of disc- and UST-compatible
wheels for commuting and dirt roads.

Allroad Elite Road+ Disc

2019 Mavic ALLROAD ELITE ROAD+ DISC

The Allroad Elite Road+ Disc is Mavic's first road-orientated
wheel in the 650B size that's popular with riders who want extra grip and
cushioning compared to 700C. A 650B wheel is slightly smaller, but with a
fat tyre the whole shebang ends up about the same size, so 650B wheels
will fit some 700C bikes without affecting the handling. The Allroad Elite
Road+ Disc has a 25mm-wide UST rim in Maxtal alloy, with a welded SUP
joint and conventional spoke drilling.

Buy if: You want the ability to run very fat tyres

Allroad Elite UST

2018_mavic_allroad_elite_ust.jpg

The Allroad Elite UST is the only rim-braked wheelset
in the Allroad family. It's only available with standard 9mm quick
releases, so it's suitable for making older bikes a bit off-road capable
if they have the tyre clearance, and they'll make great super-tough
commuting wheels.

Claimed weight for the pair is 1,590g, which splits 685g/905g front and
rear. That's only a little more than the Ksyrium Elite USTs with which
they share features like steel double-butted spokes. They come with 30mm
Yksion Elite Allroad tyres.

Buy if: You want light but beefy do-everything wheels

Allroad Elite UST Disc

2018_mavic_allroad_elite_ust_disc.jpg

The Allroad Elite UST Disc wheels sound like they're the disc-braked
equivalent of the Allroad Elite UST, but there are lots of differences
aside from the disc compatibility. For a start they have 24 spokes in both
wheels where the Allroad Elite UST has just 18 in the front wheel.

Like the Ksyrium Pro UST Disc wheels, the Allroad Elite UST Discs are
compatible with a wide range of axle and quick release designs, including
12mm through-axles and 15mm front axles. These are wheels designed for
versatility.

A pair of Allroad Elite UST Discs weighs 1,720g (F:795g, R:925g). They
come with 30mm Yksion Elite Allroad or 40mm Yksion Elite Allroad XL tyres.

Buy if: You want off-road-capable disc-braked wheels

Allroad Pro UST Disc

2018_mavic_allroad_pro_ust_disc.jpg

The top model in the Allroad range, the Allroad Pro UST Disc saves weight
with details like a 20-spoke front wheel, carbon fibre front hub body and
Zicral spokes and the Fore drilling that leaves the tyre side of the rim
intact. That pushes the price up, but at 1,610g per pair (F:730g, R:880g)
they're a respectable weight for wide-rim disc wheels.

Like the Allroad Elite UST Disc wheels, this pair comes with your choice
of 30mm Yksion Elite Allroad or 40mm Yksion Elite Allroad XL tyres.

Buy if: You want light wheels for gravel racing and
endurance riding

R-Sys SLR

R-Sys.jpeg

The R-Sys SLR uses hollow carbon-fibre spokes that
allow Mavic to build a wheel that’s extremely stiff laterally. Mavic calls
this Tracomp technology because the spokes work in both traction and
compression to maintain the wheel’s shape whatever forces you throw at it.

R-Sys spokes.jpg

The R-Sys SLR also features Mavic’s Exalith technology (see Ksyrium Pro
Exalith, above) to improve braking and reduce rim wear.

Available in a clincher version only, the R-Sys SLR wheelset weighs just
1,295g (555g front, 740g rear). They're Mavic's lightest clinchers.

Buy if: You want a light weight combined with an
excellent level of stiffness.

Aero wheels

Cosmic Elite UST

Cosmic Elite.jpg

Cosmic is the name that Mavic gives to its mid-depth wheels that are
designed with aerodynamics in mind. The Cosmic Elite UST
is the most accessible model, with 30mm-deep aluminium rims, aluminium hub
bodies, and bladed steel spokes. In terms of materials, this is
essentially an aero version of Mavic’s basic Ksyrium UST.

Buy if: You want a tubeless-compatible aero wheelset at
a budget price.

Cosmic Elite UST Disc

2018_mavic_cosmic_elite_ust_disc.jpg

Mavic added several disc-compatible models to its range in 2018,
including these accessible aero wheels. They're largely the same as the
rim-braked version, but with 24 spokes per wheel.

Buy if: You want your value-for-money tubeless aero
wheels disc compatible

Cosmic Pro Carbon

Cosmic Carbon 2017.jpeg

Tweaked for 2017, the Cosmic Pro Carbon is an
entirely different design with 45mm-deep rims that feature elliptical
sidewalls. Those rims are Maxtal aluminium with carbon-fibre flanges
bonded on to improve the aerodynamic performance.

mavic-cosmic-pro-carbon-1.jpg

The extra material does add to the weight. A pair of Cosmic Pro Carbons
comes in at a claimed 1,650g (735g front, 915g rear).

For 2017, Mavic introduced a disc-compatible version of the
Cosmic Pro Carbon
. The disc mounts unavoidably add weight,
bringing the total to 1,770g (835g front, 935g rear). They've nominally
been discontinued, but some retailers still have stock.

mavic_cosmic_carbon_pro_exalith.jpg

The Cosmic Pro Carbon Exalith is the same rim-braked
wheel except that the rim has been given Mavic’s Exalith 2 treatment (see
above) to improve durability and braking performance.

The combination of an aluminium brake track and a carbon fibre fairing
isn't the lightest way to build an aero wheel, but it does keep the price
under control while delivering almost all of the speed benefits of deep
rims.

Buy if: You want aero performance while retaining good
braking on an aluminium brake track.

Cosmic Pro Carbon UST

2019 Mavic COSMIC PRO CARBON UST

The Cosmic Pro Carbon UST is a new model for 2018/2019 with
all-carbon UST tubeless-ready rims — the aluminium brake track of previous
Pro Carbons is no more — and steel spokes. There's also a special edition
with Tour de France graphics, imaginatively named the Cosmic Pro
Carbon UST Tour de France
.

2019 Mavic COSMIC PRO CARBON UST TdF

These should be popular. At 1,650 grams (F 745g/R 905g), the weight for a
pair is decent for 40mm aero wheels, they have a 19mm internal width to
give a sensible profile to 25mm and 28mm tyres and they're reasonably
priced at an RRP of £1,350 (an extra hundred quid gets you the Tour
version's funky graphics).

There's also a disc-brake version, the Cosmic Pro Carbon UST Disc,
at the same weight though split F 760g/R 890g and when they become widely
available next month you'll be able to choose a 650B version too.

Buy if: You want light, fast all-round road wheels

Cosmic Pro Carbon SL

2018_mavic_cosmic_pro_carbon_sl_ust.jpg

The Cosmic Pro Carbon SL family have 40mm deep full carbon rims and again
there are versions for rim and disc brakes and for clincher and tubular
tyres. For 2018 the clincher versions have Road UST rims.

We were very impressed by the Cosmic Pro Carbon SL when we reviewed them.
They weigh what they supposed to (and for more than most people spend on a
complete bike, they'd better), they're fast and Mavic's new brake track
treatment means stopping in the wet is almost as good as in the dry, an
area that traditionally been a weakness of carbon rims.

Read
more: Mavic Cosmic Pro Carbon SL clincher wheels review

As you'd expect, they're light. The rim-braked Cosmic Pro Carbon
SL UST
weighs 1,490 g/pr (645g front, 805g rear), while the Pro
Carbon SL Tubular
comes in at just 1,410g (620g front, 790g
rear).

The disc-brake versions are a little heavier as you'd expect. The Pro
Carbon SL Disc UST pairing
weighs 1,570g (750g front, 820g
rear) while the Pro Carbon SL Disc tubulars are 1,540g
(730g front, 810g rear).

The 2019 versions of the Cosmic Pro Carbon SL seem to be different only
in cosmetics and price — they've gone up quite a lot. Mavic says "This UST
Road Tubeless wheel is so fast we had to re-engineer it for better
braking," so, to give them the benefit of the doubt, we assume you're
getting a new brake track technology that they're otherwise keeping quiet
about. Doesn't explain the price hike of the disc models though.

Cosmic Ultimate Tubular

Cosmic Ultimate.jpg

The Cosmic Ultimate Tubular also has a full-carbon 40mm
deep rim. The spokes are carbon too, as is the front hub body. This all
drops the weight down to a claimed 1,250g for the wheelset (555g front,
695g rear).

The Cosmic Ultimate is the wheel that you’ll see used most frequently by
Mavic sponsored pro teams because of its light weight and a depth that’s
suitable for a variety of terrains and conditions.

Buy if: You want a professional level wheelset that's
light and versatile.

Cosmic Ultimate
UST

mavic_cosmic_ultimate_ust6.jpg

The latest addition to the Road UST line-up, these ultra-spendy wheels
are squarely aimed at getting Mavic's sponsored racers on tubeless tyres.
Mavic claims a weight of 1,300g for a pair, which is very impressive for
aero clinchers, and says the aerodynamic performance is on a par with
comparable wheels like Zipp's 303 Firecrests. Mavic also claims individual
weights of 595g for the front wheel and 795g. They're slated to be
available in early 2019.

There's no disc brake version as yet, and while we expect Mavic will
eventually come up with some sort of superlight disc-brake aero clincher,
it's going to be a challenge to mount a rotor on a Cosmic Ultimate style
carbon hub.

Buy if: You want a low-weight combination of the latest aero and
tubeless technologies

Hyperaero wheels

​Mavic refers to wheels with rims deeper than the Cosmic's 30mm and 40mm
as Hyperaero, and has replaced the old CXR wheels with four new models
under the Comète name, formerly reserved for a time trial rear disc.

Comète Pro Carbon SL

2018_mavic_comete_sl_carbon_crop.jpg

These are very much Mavic's most modern aero wheels, with 64mm deep, 26mm
wide NACA profile rims. They're reasonably light too: the Comète Pro
Carbon SL UST comes in at 1,635g per pair, a few grams less than rivals
like DT Swiss PRC 1400 Spline wheels.

Since there still aren't many people using disc brakes in time trials and
triathlons, we suspect the most popular wheels from this group are going
to be the tubular and UST versions.

2018_mavic_comete_pro_carbon_sl.jpg

At 1,490g a pair the Comète Pro Carbon SL Tubular is
the lightest model in the range, which is as you'd expect: with no mounts
for a disc rotor or hooks for a tyre bead, a rim-braked tubular is still
the lightest way to make a wheel.

Nevertheless, as we mentioned, the Comète Pro Carbon SL UST's
1,635g is pretty impressive for a clincher wheel with a rim this deep.
That splits out as 740g for the front wheel and 895g rear.

If you're looking for an extra turn of speed for a modern endurance bike,
then the Comète Pro Carbon SL UST Disc could be for you.
A pair weighs 1,755g (F:845g, R:910g).

Finally traditional and modern collide in the Comète Pro Carbon
SL Tubular Disc
. A pair weighs 1,630 (F:765g, R:865g). Both
these wheels and the UST version are compatible with quick-release and
through-axle systems.

Buy if: You want Mavic's fastest aero wheels

Comète Road

Comete 2017.jpg

The Comète time trial/triathlon disc wheel, available only as a tubular,
is carbon fibre with an aluminium rim body and a Mavic Exalith brake track
for improved braking and durability. The walls are asymmetrical: convex on
the driveside and lenticular on the non-driveside.

Buy if: You're after a disc wheel that offers a
top-level braking performance.

Are the prices correct?  For example, the  Cosmic Pro Carbon SL were £1,440 at launch - they now retail at £1,600.  Great wheels, btw.

Sadly I have found, and had corroborated by several club mates, that Mavic's quality control went downhill several years ago. Once a byword for excellence in both racing and touring rims, and an innovator of factory-built wheels and straight-pull spokes, now they seem to often come with highly variable spoke tension and bits of welding material rattling around inside the rim.

Echo that and add freehubs apparently made from camembert or substandard brie.

Does anyone know whether the new Open Pro - which I don't think is listed here - unless they've called it a Kysirium Pro - will be sold as a rim only option?  I've been riding Open Pros for a while:  they make an excellent, robust wheel and are an antedote to our appalling roads...

interesting - I've not seen those new ones on sale anywhere yet - if you want the old ones it maybe a good time to grab them - the best deals I've seen are Wiggle for the black or silver, Acycles or Fatbirds for the CD

I have a couple of sets already so I'm good - but I'm very interested in trying the new ones.  No one seems to know much about them beyond the article I posted.  My LBS spoke to Mavic, but they didn't give out much info either.  I'll try again tomorrow....

420g per rim too...that's 45g lighter than my HEDs...and anything comparable on Strada's website...

There's a discussion on the CUK forum about them, going to be a bit spendy at circa £70 and the 'ceramic' coating is not going to last anywhere near as long as the older variant, not even close, so for me personally who still uses the older ceramic Mavic rims (Open 4 and Open SUP) I think I'll continue to buy up the sweepings that no-one wants anymore.

A few other companies made ceramic rims too but becoming like rocking horse shit to find in the UK.

I still use my ksyrium SSCs and Heliums, they are both MAXTAL alloy and the SSC have Zicral spokes and weigh approx 1700g and are very very sturdy, the heliums are a great wheelset for a multitude of sins and were quite popular with cross country way back when.

As discussed elsewhere Mavic either had great foresight or just got lucky with their freehub design so that the older wheels could take a Shimano 11 speed. the freehub bodies are made of steel too so for the sake of a few grams you don't have to worry about the sprockets embedding themselves in the body.

My best mavic rim in terms of value is an MA2, still going strong on a Sansin sealed hub on my commuter/utility and it was second hand to me 6 years ago.

I spoke to Mavic yesterday who confirmed that the new Open Pro rim would be available in Q3 - September - but with no specific release date yet decided.  Prior to that they will be releasing two wheelsets; one special edition with Chris King R45 hubs in July, and one without Chris King hubs.   As Chris King hubs aren't compatible with Mavic's blade-style spokes, I guess this means the eyelets will be narrow-gauge....

Just spent five days in Tuscany riding a new Canyon with Kysrium Pro Exalith SLs. 

In summary: very poor.

The braking was not as good as plain alu rims, even when toed in. The screeching did subside, but there is no way the braking was better than other untreated rims. 

Flex...!!!  every time I got out of the saddle, even gently, the wheels flexed and the rims rubbed. Had to loosen off the brakes on every climb. They even rubbed when seated, if you steered left or right creating lateral movement. 

I was riding with an Olympian and former pro and he was taken aback with how poor the perfomance was. 

 

Sigh.....

So in 2017 Mavic have managed to produce a less aero and less stiff wheelset than the 2011 Reynolds 46's i bought years ago and still going strong, at the same weight! (1190 g).

But on the other side, I've been riding a pair of Cosmic Pro Carbon SL wheels for the last 6 weeks and they're excellent.  

Braking is outstanding - a little too much so on occasion - and they don't flex at all, even under my 90kg.

Surely everyone knows by now that any cyclist's needs can be fulfilled by just two factory wheelsets: Campagnolo Zondas and Campagnolo Boras.

But just try getting spares these days.

I waited 5 months for a Eurus rim and I only managed to get Bullet spokes by shopping in Germany. Condor couldn't get them for me.

Long gone are the days when shops like J D Whiskers could sell you the parts to rebuild a 20 year old Campag rear mech.

Conversely, getting Mavic wheels fixed / rebuilt is pretty easy.

It is a shame that you're blaming the brake rub on the wheels. Typically, brake rub is coming more from the frame and not the wheels. Unless the wheels have an incredibly flexy hub / axle ... which Mavic wheels are definitely NOT known for ... it seems like this was more about the frame.

You had wheels that flexed when you steered ? Something very wrong there. That's not typical, doesn't even make much sense.

I wonder if this article was written after a test of the wheels?

"Kysrium Pro - Buy if: You want a lightweight wheelset that doesn't compromise on durability."

Rims wore out & freehub went after 2 winters of hard use.  Not a patch on the older models.

"R-Sys SLR - Buy if: You want a light weight combined with an excellent level of stiffness."

What level of stiffness?!  Wet noodles are stiffer.  Thankfully these got written off by a car and replaced.  Braking was superb though.
