UCI rules? Forget ’em! Is this the most unusual road bike of the year? Plus more tech news from POC, Bianchi, Ortlieb, Santini, Cinelli and more…

Check out Princeton’s ultra-aero wheels, POC’s new helmet for bike and snow, Cinelli’s latest road bike, and “the lightest 3D-printed titanium bottle cage in the world”

This edition of Tech of the Week is packed to the rafters with new clothing from Bianchi and Santini, a just-released road bike from Cinelli, and POC’s latest helmet that’s designed for both bike and snow, but we’re starting with a bike that totally ignores UCI rules and ditches the seat tube…

WTF?!? Where’s the seat tube?

And the prize for the most unusual-looking road bike of 2023 goes to… Baldiso and CarbonWorks for the Baldiso One.

2024 Baldiso One - 1 (1)

Ditching the seat tube isn’t an entirely new idea but German brands Baldiso and CarbonWorks reckon they’re “on the verge of an exciting revolution” with their new design.

> Cage fight: CarbonWorks founder claims Topeak bike bottle cage infringes brand’s own design 

“Our mission was to rethink the conventional UCI-restricted frame shape and present a completely different design; a road bike that not only stands out from the crowd but is completely unique,” says Sebastian Baldauf, founder and owner of Baldiso. “It should be visible from 500 metres away and attract attention.”

The Baldiso One (or B1 for short) will doubtless do that. With no seat tube, it’s bound to attract a second glance.

CarbonWorks founder and owner Simon Bühler says, “Fibre composite materials offer enormous possibilities in component design, but when the material was discovered in racing cycling, design freedom was nipped in the bud by regulations, and racing was hardly allowed to differ from the tried and tested classic geometry of steel diamond frames.”

He’s referring to UCI rules saying that a bike’s frame must be of a traditional pattern – built around a main triangle – for road (and track and cyclocross) competition. You must have a seat tube and “bicycles with extravagant shapes that do not represent bicycles as understood by the UCI” are out, according to the sport’s governing body.

“I started the sketches without any ‘design role model’ and just tried to connect the direct lines of forces between the basic structural elements of a frame,” says Simon. “The idea was to think: which lines would nature choose to connect these elements? How would plants – maybe the branches or roots of a tree – find their way to each other? Where should be thicker and where is reinforcement needed?

“Sebastian and I believe that there should not only be bikes made for racing but also road bikes that please the eye of the rider. Bikes that are just fun to ride. This might motivate the rider to train more than just knowing that the bike is maybe 2% more aerodynamic or 90g lighter.

“We’re also hoping for a slightly different riding experience without the seat tube – which remains to be proven.”

That’s because the B1 frame doesn’t yet exist. Right now, Baldiso and CarbonWorks are building a full-size 3D-printed model of the bike to check the final details, before the expensive process of making a first mould and then the final prototype for stiffness testing.

“We can use the material we save from the seat tube to strengthen the other tubes, but weight may be slightly higher for this frame,” says Simon. “We calculate it’ll weigh between 920g and 1,070g. The first test rides should be possible in about March/April next year.”

2024 Baldiso One - 2 (1)

Specially adapted components have been developed for the B1, including a handlebar/stem unit and tri-spoke wheels (not pictured). Other wheelsets will also be available.

The B1 will come with a 9g bottle cage while a new holder for two bottles is said to be in the final design phase. A special adapter allows you to mount a front derailleur if you’d prefer a double chainset to a 1x system.

As mentioned, bikes without seat tubes have certainly

been developed before. We showed you an Urwahn Bikes X Vagabund Studfuchs commuting bike in 2019, for example, and then there was the Superstrata that was launched with a big song and dance back in 2020. The well-publicised issues with that bike were largely down to supply. 

The Baldiso One will go live on the Kickstarter crowdfunding site in the coming week. You can also pre-order a frameset online for €5,540, which converts to about £4,850. Complete bikes start at €9,770 (about £8,550). That’s for a Shimano 105 Di2 build.  Delivery is expected to begin in March 2024.

A cool innovation or change for change’s sake? Let us know what you think.

POC’s new Calyx helmet is designed for riding bikes AND snow sports

If you’re the adventurous type who likes to mix things up a bit, POC says that the new Calyx is its first helmet that’s certified for skiing and mountaineering as well as cycling. You weren’t expecting that, were you? Okay, this is more likely to be a bonus in POC’s Swedish homeland than it is in the usually snowless UK, but you never know.

2023 POC Calyk - 1 (1)

“Thanks to its development and design approach, the Calyx is a helmet that will shine in skiing/snowboarding, mountaineering, and cycling environments, and can easily be used to cycle to the lift area, and from there to the back country,” says POC. “Equally it can be used solely for skiing laps, playing in the park at a ski resort, taking a day to focus on climbing skills, or on the daily commute in the city to and from the office.”

POC says that certification for mountaineering requires a very different testing and development process than for cycling and skiing because the helmet “must be able to withstand significant falling and penetrative forces which could occur during a rock fall”.

2023 POC Calyk - 2

The linear channels inside the Calyx are said to have been inspired by POC’s road and mountain bike helmets, while a “three-stage integrated ventilation adjustment” allows you to fine-tune the performance. You get a Mips Evolve safety system and fit adjustment is via a rear wheel.

The Calyx (with an ABS thermoplastic shell) is priced at £220 while the Calyx Carbon (with a carbon shell) is £380.

Cinelli unveils new Pressure ADR road bike

Cinelli has announced the launch of its latest road bike, the Pressure ADR, based on its existing Pressure.

2023 Cinelli Pressure ADR - 1

“The Pressure ADR combines an aggressive riding position (the same stack and reach found on our aero racing Pressure platform) with increased comfort and more predictable handling characteristics thanks above all to increased rake and wheelbase, round seat tube, 27.2mm seatpost and lowered seatstays,” says Cinelli.

> Check out our review of the Cinelli Pressure Disc Ultegra 11x Hydro Bike 

2023 Cinelli Pressure ADR - 2

The Pressure ADR has a Columbus carbon monocoque frame that weighs a claimed 990g (size medium), while the fork is 420g. It comes in five sizes and takes tyres up to 30mm wide.

You’re looking at £1,999 for the frame kit with complete bikes starting at £3,199. That’s for a Shimano 105 (mechanical) build. A Shimano 105 Di2 bike is £3,799.00, and a Pressure ADR with Ultegra Di2 is £4,399.

Check out the sub-15g titanium bottle cages priced at £330 a pair

Whoa! We’ll run those figures past you again: each bottle cage is sub-15g (14.7g, to be precise). And a pair is priced at £330 (€380, to be precise). We’re talking about the new Superleggero Ti bottle cage from Italy’s Alpitude – based in the Alps, you see – billed as “the lightest 3D-printed titanium cage in the world”. 

2023 Alpitude Superleggero Ti bottle cage - 1

“We use SLM [selective laser melting] technology to produce this special version of our best-selling Superleggero carbon cage,” says Alpitude’s Andrea Sega.

“We started from our carbon cage design and we adapted it with a ‘Drillium’ design and the new additive manufacturing material,” says Andrea (Drillium being the word used to describe a product that’s full of holes to save weight).

“Titanium is the best material for this kind of use, and for the first time we offer customers the chance to get a unique kind of product in the cycling market. It is designed to get lower weights while keeping the bidon [water bottle] as tight as the carbon model.”

2023 Alpitude Superleggero Ti bottle cage - 2

Alpitude made 99 pairs of these bottle cages, each numbered and presented in a wooden box. The ones made available on Alpitude's website sold out almost immediately. Some others will be available through Alpitude dealers around the globe in the first week of December. Due to the high demand, it's possible that another version of the Superleggero Ti will be produced in the near future.

You can also buy Alpitude’s Superleggero carbon cages with an even lighter claimed weight of just 9.5g (+/-5%) without screws. These are priced €79.90 to €99.90 each, depending on the finish. Bargain!

Princeton makes Wake 6560 Evolution wheels faster... and more colourful

Princeton – or Princeton CarbonWorks if you want to be formal about it – has updated its Wake 6560 wheels with a new shape and a whole load of new colour options. They were already amongst the most distinctive wheels out there courtesy of their wavy rim profile; the new colours push that on a level or two.

2023 Princeton Wake 6560 Evolution wheels - 1

The most important bit, though, is the performance and the headline here is that Princeton claims the Wake 6560 Evolution wheelset offers a 3.88W saving over the previous Wake 6560 Strada at 30mph (48km/h) – (tested in the A2 Wind Tunnel using 25mm Continental Grand Prix 5000 S TR tyres). Princeton also claims a 7.68W saving over Zipp’s 454 NSW wheels, and 7.77W savings over Shimano C60s.

2023 Princeton Wake 6560 Evolution wheels - 3

“Our new Evolution profile matches alternating deep and shallow rim sections with alternating spoke sides,” says Princeton. “Mechanically, this allows the steeper, high tension spokes (drive side rear spokes and disc side front spokes) to connect to a deeper rim section, thereby flattening those spoke angles. The change in bracing angle helps balance spoke tensions, creating a stiffer, more uniform wheel.”

The rim is wider than previously (21mm internal, 28.2mm max external; it is said to be optimised for 25mm tyres) yet 10g lighter thanks to the overall shorter cord length of the inner edge.

2023 Princeton Wake 6560 Evolution wheels - 1 (1)

The rims remain hooked because Princeton believes this is “the safest and fastest solution for road riding and racing”.

Princeton is offering the wheels in various colours although UK distributor Ison says it’ll only offer black decals as standard, with colours available as special order. Pricing has yet to be confirmed but it’s expected to be about £3,900 per wheelset.

What an utterly ugly bike.

Sredlums | 3 months ago

About that seattube-less bike, I just don't get it.

Why is it that every time some brand/designer comes up with that same idea, everybody reacts as if it is totally new and innovative. The article even mentions a few of them (there are many more), but still goes on as if it is really groundbreaking.

You may like the looks, or not, that's fine, but being a bit more critical wouldn't hurt. Designing it is easy, buiding in in to a bike that is actually any good is much harder. Why not test the ones that are actually sold, and report on them. Way too much credit for what is basically just a fancy render.

For those interested in a miniature bike, please be aware that there are others that do it WAY better than the company/person metntioned in this article.

Look at these two accounts on Instagram, and you'll see for yourself that there's a night and day difference:


Not affiliated, just an admirerer of their work. Don't know anything about their prizes and lead times etc.

I'm all for innovation when it makes things better, but from what is stated here, the Baldiso is in every way worse than a normal bike - heavier, less aerodynamic, can't put bottle cages in the normal place, can't use a normal 2x gear, ride characteristics/stiffness/comfort unknown. Their only selling point is their claim that it "pleases the eye" and whilst I'm happy to let aesthetics influence my decisions, and whilst this bike is no doubt has a distinctive style, I can't say I find it particularly attractive. Plus strong vibes of the Superstrata (also launched via crowdfunding) and we all know how that went...

If someone's going to go to the trouble of making a UCI-noncompliant bike, it would be cooler if they made a beam bike like the Y-foil.

The Y-foils look cool, but are there big advantages with that shape?

I'm usually fairly sceptical about designs that go away from the usual double triangle because the double triangle is the strongest/lightest design.

chrisonabike replied to adamrice | 3 months ago

Non-UCI compliant?  Beam?  How about the Soup Dragon from the late Mike Burrows?

(Video also features him using a cargo bike he designed to transport another bike he designed to the track - that's cool...)

chrisonabike replied to adamrice | 3 months ago

When you said "beam bike" after I'd got Tron out of my head I thought it would be like the "stick bike" type of thing, like a Bachetta or a Pelso Brevet.
