Effective Rim Diameter (ERD) is 557mm to ensure accurate spoke length calculation and long-term serviceability across standard 32H MTB builds.
Performance Design
X35 is designed for aggressive trail riding where tyre support and rim durability matter more than absolute weight. The 30mm internal width stabilises higher-volume tyres, improving cornering confidence and reducing tyre squirm in technical terrain.
The carbon structure and 32H drilling are tuned for strength under impact and consistent tracking through rough sections. You get a planted feel when pushing hard, with predictable handling when the trail gets fast and uneven.
- Maximum tyre support and cornering stability
- Strength-focused build for rough trails
- Reliable tracking through technical terrain
- Confidence under heavier riders and higher loads
Intended Use
X35 is built for trail and enduro-style riding where durability, traction, and control take priority. It is ideal for riders who want a wider rim platform for modern tyres and a stronger spoke count for long-term reliability.
This is the wheelset for pushing harder, riding rougher trails, and carrying speed through corners — without feeling fragile.
- Aggressive trail riding
- Enduro-style terrain and technical descents
- Riders using 2.35–2.6″ tyres
- Heavier riders or riders prioritising durability
Build Platform
- Standard drilling: 32/32H
- Axle compatibility: Boost (standard)
- Spoke options: Sapim Race / Sapim CX-Ray
- 27.5″ builds available via RHC Custom Build
