The Pacenti Forza-C 30mm Disc Clincher wheels are a new design from the ground up and they are absolutely lovely. You can feel the quality of the build as soon as you start riding, and their stiffness is impressive considering their very svelte 1,378g weight. Pacenti hasn't even stung you on the price either.

  • Pros: Fast and responsive, impressive price given the stats
  • Cons: Compatibility only with tubeless tyres might not appeal to all

Pacenti builds these wheels by hand in the UK and it shows – not necessarily the UK bit, but definitely the handbuilt part. The wheels feel tight and stiff, but the spoke tension allows enough comfort through to take out any harshness.

The tyres will obviously do the majority of this, but using the same tyres, pressures and so on between the amount of wheels I get through, you can feel the tiny little differences.

Speaking of tyres, the Forza-C rims are hookless so they are only compatible with proper tubeless tyres, none of that tubeless ready stuff, so that might limit their appeal somewhat to prospective purchasers. You can fit an inner tube if you like, as long as you use a tubeless-specific tyre.

If I'm honest, as much as tubeless is making inroads into all aspects of road riding, personally I haven't really felt the need to make the transition. The number of punctures I suffer on both road and gravel throughout the year considering my mileage is minimal (probably two or three), so I haven't bothered. I'm not fussed about running lower pressures for comfort either, which is probably the main reason I haven't swapped.

That aside, I had some tubeless tyres kicking around, the Ere Research Genus in a 24mm width, tyres that admittedly I wasn't that impressed with when it came to their ride quality, but they did little to damp the feedback from the Pacentis.

Fitting them was easy on the 21mm wide rim (internal) using the rim tape and valves that came with the wheels, and I managed to get them inflated with just a standard track pump after a bit of fettling and a few videos – it being the first time I'd used hookless rims.

The wheels were running true straight out of the box and that is exactly how they stayed throughout testing.

The 30mm-deep carbon fibre rims have an asymmetric spoke bed, to offset the dishing, creating a stronger wheel thanks to better spoke tension to cope with today's current wide-ranging cassettes and the width of adding disc brakes to the hubs.

They are laced with 24 spokes front and rear in a two-cross pattern for strength, using Sapim's CX-Ray spokes up front and its D-Lights at the rear – something we see on a lot of builds, especially the drive side as the D-Lights are very strong, being primarily designed for mountain bike use.

Hub-wise Pacenti uses its own in the build, which are fitted with EZO bearings. They run beautifully smooth and have stood up well to varying weather conditions.

It's good to see the freehub getting a bite guard, too: a small strip of stainless steel to stop the cassette gnarling up the alloy body under load.

I spoke up top about how stiff and comfortable these wheels are, but that is only the half of it. What this build has created is a set of wheels that are not only durable and robust but impressively efficient.

A pair of wheels weighing (without valves and tape) sub 1,400g (747g rear, 631g front) are never going to feel sluggish, and these certainly don't, but they don't feel like they have sacrificed anything to achieve that. Acceleration, climbing and sprinting are delivered without hesitation and... well, I can't really sum it up more than that these wheels deliver the all-round package, such a joy to ride.

> Buyer's Guide: 10 of the best tubeless wheels for under £1,000

And on top of all that, you can have all of this for a penny under £900!

Yes, it's still a wedge of cash, but from some of the more mainstream brands you'd be looking at getting on for double the price.

Similar options such as the Token Prime Ventous Carbon Disc wheelset will set you back £1,099.99. They certainly impressed Sean, so it's not a bad comparison and they have a decent weight of 1,479g.

And for a little less, the likes of Parcours with its Grimpeur wheelset (£819/1,406g) and JRA's £850 Gecko wheelset are worthy competitors, and show what quality company the Pacentis find themselves in.

Conclusion

The Forza-Cs are up there with some of the best carbon disc wheels on the market thanks to quality components and a great build. If you've embraced tubeless and want one of the lightest, durable, best value for money wheelsets out there then this could be the one.

Make and model: Pacenti Forza-C 30mm Disc Clincher wheels

Size tested: 700C

Tell us what the wheel is for and who it's aimed at. What do the manufacturers say about it? How does that compare to your own feelings about it?

Pacenti says, "Hand-built in the UK. We'll build you a Forza-C wheelset complete and ready to ride. Enjoy an ≈1470 gram wheelset built with 24h drilling front and rear, Pacenti hubs front and rear, Sapim CX-Ray spokes in front, Sapim D-Light spokes in back, and laced two-cross to optimize strength and low weight. Hubs are configured as 12mm front and 12mm x 142 rear. QR and 135 x 10mm rear are available through end caps purchased separately.

"Our Forza-C rims are the heart of this wheelset, and they are optimized specifically around tubeless tires. The inner width of 21 mm provides for more air volume (comfort) and improves tire profile (control). The asymmetric profile provides for good spoke tension when lacing to offset hub flanges. These rims are the result of a clean sheet design that brings our best thinking to the table on what a rim should be."

The Forza-Cs are a great all-round package at a decent price.

Did the wheels stay true? Any issues with spoke tension?

No issues at all throughout testing.

How easy did you find it to fit tyres?

No problems at all once you get used to hookless rims.

How did the wheel extras (eg skewers and rim tape) perform?

The rim tape was easy to fit and if you need quick release adaptors these are available as an optional extra.

Tell us how the wheel performed overall when used for its designed purpose

They're great all-round. There's nowhere that they don't really deliver.

Tell us what you particularly liked about the wheel

A quality build throughout at a great price.

His fascination with gravel bikes is getting out of control too!

Surprisingly high max pressure being quoted for a hookless rim. These wheels do sound very good though.

"The wheels feel tight and stiff, but the spoke tension allows enough comfort through to take out any harshness."

 

Someone help me understand the last part of this sentence, and does it contradict the first part?

Sounds like waffle to me.

I don't see why you'd want anything other than stiffness in a wheel though there's usually a compromise between stiffness and weight (i.e. it usually takes more material to make something stiffer unless you do something clever). Tyres are where you want the material to be supple and compliant.

From a consumer buying perspective there's no meaningful difference between 'tubeless' and 'tubeless-ready'. You can either run a tyre tubeless or you can't.

The UST spec tyres, e.g. Mavic, are tubeless - most other are tubeless ready. Given that you'd probably want to put sealant in anyway, the difference is generally moot (beyond a potential thicker side-wall in the tubeless ones).

Welcome to the world of road.cc reviews. Leave your engineering knowledge at the doorstep. They just make s*@( up that sounds good. Seriously.

But the new tubeless standard is hooked!!! Therefore these are not "proper" tubeless rims.

At this point, now that there is a standard for tubeless, I would not buy any rim that is not UST-compliant. And this rim is not.
