If you’re looking for wider rims without the weight penalty but with all the handling advantages carbon rims offer, these could be for you. They are 42mm wide externally with a 35mm internal width.

Weighing around 1780g for a 27.5 wheelset with CX Ray spokes, they are a similiar weight to much narrower XC alloy rimmed wheels. These can be comfortably with tyres between 2.3 and 2.8 widths. They are asymmetric rims to give more even spoke tensions on each side of the wheel for an even stiffer stronger wheel.

Approx. wheelset weights:

27.5 Sapim CX Ray: 1740g;      27.5 Sapim Race: 1830g;       29er Sapim CX Ray: 1840g        29er Sapim Race: 1930g

Rims are constructed from unidirectional Toray T700 carbon and have a hookless bead inner profile. They are asymmetric to give more even spoke tensions on each side of the wheel for an even stiffer stronger wheel. Like all of our wheels, they are built on Hope Pro 4 hubs in your choice of colour and available in all sizes including Boost and with either freehub arrangement. Choose any combination of rim decal colours to match your hubs and bike.

Standard wheels are built with Sapim Race 2.0-1.8-2.0 double butted spokes which are wider gauge than most competitors build with but are up to the job for the type of riding these wheels are built for and do not snap.  If you would like the same strength at a lighter weight, choose Sapim CX Ray spokes for an approx. 90g per wheelset weight saving – the most expensive and fatigue resistant spokes on the market (adds £70 but check out the cost of one of these spokes online and multiply by 65).

Prices include free UK delivery and we deliver to most other European countries for a small extra cost.
