Our wheels are assembled and adjusted by hand in China and are guaranteed to the highest quality standards! The wheel hub is CNC processed by our aerospace grade aluminum material, which has high fatigue strength and light weight. Even in the harshest environment, anodizing can ensure aesthetics and prevent corrosion. Carbon fiber rims are handmade by workers who have many years of experience in our rim factory. The strength and fatigue resistance of the rim are improved through a special laminated carbon fiber prepreg. CRW rims do not need to be painted and can maintain better strength, which provides additional reliability and strong impact resistance as well as light enough weight.The inner width of the rim is 21mm and the outer width is 28mm. It has considerable lateral stiffness and excellent aerodynamic performance. On flat ground, this wheel with aerodynamic contours and Aero Sapim CX-Ray spokes will help you.

Rider Weight Limit

The rider weight limit on this wheel set is 110kg including the weight of bike and luggage.

Light, Aero Rims

When it comes to saving weight on a set of wheels, the rims are the place to start - this is where you feel the greatest benefit in speed and handling.

Lighter rims improve acceleration and climbing performance - They also improve the handling and overall flexibility of the bicycle, making riding alive. 

Our Ultra rims are made of Japanese Toray T700 and T800 carbon fiber, and use a toroidal aerodynamic shape to cut air. They are 28 mm at the edge of 

the rim and widened to a maximum of 29 mm.

Easy Fit, Tubeless Ready

Suitable for both tubeless tyres and clincher tyres with inner tubes – whichever you prefer.

Suitable For A Wide Range Of Tyre Sizes

Our rims are perfect for today’s most popular road tire sizes-they have an internal size of 21 mm and are optimized for 28C tires. If you want to use wider tires,

 they can be used with tires up to 35C.

Lightweight, Straight Pull Hubs

CRW Works ULTRA straight-pull hubs , for the same weight hubs we use bigger bearings, 2x6902 front hub, 2x6902 and 2x6802 rear hubs.

36T plane gear freehub for rapid engagement and reliability.

Available with Shimano and Sram XDR freehubs.

Spokes

Sapim cx-ray aero spokes - reinforced for extra strength and durability right where it matters. Sapim double square nipples provide more support for the spokes.
