700C Ultra-Wide 35mm/36mm Internal Width Carbon Gravel Rim

DECRIPTION:

As gravel racing continues to move toward wider, higher-volume tires, rim width plays an increasingly important role in tire support and stability. The 35mm hooked / 36mm hookless internal width platform provides a broader base for 45–70C gravel tires, helping support the tire casing and maintain a more stable profile at lower operating pressures. 

With a 42mm external width and deep-section profiles from 47mm to 67mm, the series is developed for performance-oriented gravel wheel builds ranging from fast mixed-terrain riding to long-distance racing.

Features：

- 35mm Hooked / 36mm Hookless Internal Width 

- Ultra-wide gravel platform designed to provide greater support for high-volume tires.

- 47mm / 52mm / 58mm / 67mm Depth Options 

- Multiple deep-section profiles for different gravel wheelset positioning and OEM product development.

 - U-Shaped Deep-Section Profile 

 - Developed for smoother rim-to-tire integration in performance-oriented gravel wheel builds.

 - Three Carbon Layup Options 

 - Standard, Flyweight and Ultralight constructions available for different weight, rider-limit and product-positioning requirements.

 - Customization Available — Custom drilling, decals, finish and wheelset specifications available
