2026 CRW CS Series
Performance: Refined.
Headline Stats - What's New?
- Increased rear wheel widths to better match the front
- 40g lighter across the board
- Tuneable bearing preload
Chasing Perfection
In the two year life of the CRW CS Series the wheels gained massive critical acclaim from professional riders and serious amateurs alike. The combination of lightweight, comfort and responsiveness won the wheels many fans and propelled the wheels to the top of the Panda Podium best sellers chart. For the past two years CRW have been quietly working on small refinements to the winning formula.
Bigger in the Rear
While tire width will no doubt be debated amongst roadies until the end of time, it is generally acknoledged that more air volume in a tire has multiple advantages ranging from being able to run lower tire pressures without the risk of rim damage, but also more stable tire pressures as the tire deforms. Combined with the continuing trend for wider and wider tires on road bikes CRW listened to feedback and widened the rear rim to better match the front. The internal width of the rear has risen from 21mm upto 24mm with a similar increase in external widths.
Weight Reduction
While the CS series were already the lightest in their class, the 2026 version improves on that by reducing the weight of the wheelset by 40g. This means the 2026 CS 5060 (50mm front, 60mm rear) now has an official weight of just 1250g ±2%! The CS 4045 (40mm front, 45mm rear) now weighs just 1140g ±2%! These are weights that were inconceivable for disc brake wheels just a few years ago.
Bearing Preload Adjustment
Bearings are a key component in the performance of a wheelset. All bearings need a set amount of preload to provide optimum performance and guarantee a longer lifespan. In the disc brake thru-axle world the amount of preload on the bearing can vary from bicycle to bicycle. Therefore the 2026 hubs come with an adjustable pre-load system. From the factory they're preset for optimal performance on road bikes with 10-12N·m of torque through the thru-axle. However, if upon installation the user finds suboptimal perfomance of the bearings, they can loosen the grub screw, adjust the pre-load and re-tighten the grub screw. (This should be done with the wheels clamped in the bike in an as-ridden setup.) If during the life of the bearings some 'play' appears in the bearings, the preload collar can be tightened to restore optimal performance and increase bearing life.
*Due to the design of the pre-load adjustment system, the 2026 CRW wheels are only compatible with disc rotor lock rings that feature the tool pattern on the outside of the ring. These lock rings are included with the wheels and can be installed with a standard 16-notch bottom bracket tool.
There's supposed to be an epic pic of me riding the wheels here, but it's been raining for weeks so... just use your imagination.
How do they ride?
Riding back-to-back you're hard pressed to tell the difference between the old wheels. The increase in air volume at the rear means you have to drop out a few PSI for the same feeling. The 40g difference is obviously making a difference on the climbs, but it's not immediately obvious when riding.
Other than that, they retain the same riding characteristics of the previous generation. That is to say a wheelset that accelerates crazy fast, asborbs road imperfections better than it's carbon-spoked rivals and still feels direct and stiff when laying down the power.

Joe Whittingham –
The 2026 version of the 4045 isn’t a revolutionary release from CRW, but rather an evolutionary one. The previous version was already massively successful (and perhaps my favourite all-round wheelset) so the 2026 version brings 3 welcome tweaks to the table. 1) Shaving off 40g compared to the old version. 2) Adjustable preload on the hub bearings. 3) A wider rear wheel to better match the front and keep up with trends for wider tires. On the road they ride just like their 2024 counter-parts (that is to say, amazing!) acceleration is out of this world and they strike the right balance between stiffness and comfort. There’s maybe a tiny bit more comfort by the wider rear width and taking out a few PSI.

I’m very impressive by these wheels. They are crazy. Light, stiff, beautiful
Andrew Shaw (verified owner) –
My 2026 CRW 4045’s are absolutely magic.
Done over 1000 miles on them in the last few weeks.
Super light, look and feel super premium, so outstanding value all considered.
The gloss finish is very similar to my Campagnolo Ultra Bora WTO’s.
My first wheelset with carbon spokes so was a little worried they would feel harsh on our crap UK roads, but not at all.
Super service (as usual), delivered in about three weeks. Well packaged and as true as a true thing.
They have already taken some inevitable pothole abuse. P-Zero’s went on by hand no problem.
I wouldn’t hessitate to recommend PP and CRW.
I wish I could add a picture of my Colnago C68 on the CRW’s and Tavelo Avro handlebar.
