Wheel(s) DUKE SIERRA 36 / DT SWISS 370 CL
From 1139 g* to ride fast everywhere. Sierra 36 is our Elite carbon gravel wheelset for fast adventure riding, developed for riders who want to cover distance, raise the pace and stay in control when the terrain changes.
It combines a 36 mm profile, 28 mm internal width and controlled vertical stiffness to filter vibrations, preserve grip and maintain high efficiency on uneven surfaces.
Key processes & technologies:
- 28 mm internal width optimised for modern gravel tyres**
- SLR5: advanced lay-up of Toray T1100 carbon fibres and aerospace-grade resin
- SpokeCore: moulded spoke holes (24h) for a more homogeneous structure
- VFP: clearcoat-free finish, more durable and more environmentally friendly
- DRC: vibration filtering for increased comfort and precision
- AntiPinch: anti-pinch rim beads to help prevent tyre cuts on impacts
- Offset: asymmetric lacing for more balanced spoke tension and improved lateral stiffness and reliability
- Hooked / Tubeless Ready: optimum safety and compatibility with modern tyres
Result:
A fast, lightweight and confidence-inspiring Elite gravel wheelset, made to link varied terrain, hold grip and accelerate efficiently on long rides and demanding courses.
* Weight +/- 30 g for a wheelset built with NonPlus CL SP hubs and Sapim CX-Ray spokes.
** Optimal tyre width: 40 mm <> 2.2". Compatible width: 36 mm <> 2.4".

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 UD carbon & 3k Carbon rim, 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)
Nipples
Aluminum nipples with locking thread, available in 16 colors: black, red, silver, metallic grey, blue, aqua blue, gold, light gold, dark green, mint syrup green, lime green, lilac, pink, fuchsia pink, orange, and oil slick.
