Crash replacement
We offer a crash replacement programme for carbon wheels. In case of accidents or heavy falls, violent shocks can damage your rim and make it impossible to use. With our Crash Replacement offer we offer you a service that allows you to replace your rim under special conditions: You get a 50 percent discount on the price of the rim (UD SLS carbon) 40 percent (3k Carbon), as well as the parts and the disassembly/reassembly. This offer is valid (for life) for an unlimited period of time for DUKE carbon rims and is transferable in the event of sale of the wheels to a third party.
Sapim Spokes
Sapim is THE go-to spoke brand, manufactured in Belgium since 1918. Several spoke models are available, depending on compatibility with your riding style and chosen rim:- Sapim CX-Ray: flat spoke, very light, durable, aerodynamic, and offers a very dynamic ride feel (309g / 64 pcs / 292mm)
- Sapim CX-Sprint: flat spoke similar to the CX-Ray but thicker for even more stiffness (373g / 64 pcs / 292mm)
- Sapim D-Light: round spoke, light and durable, with a central section diameter of 1.65mm, good value for money (344g / 64 pcs / 292mm)
- Sapim Race: round spoke, strong and stiff with a central section diameter of 1.8mm (408g / 64 pcs / 292mm)
