Gravel optimized performance

The Venn 400 C gravel rims combine aerodynamic efficiency with the durability demands of off-road riding. The modern 25mm internal width is optimized for gravel tires from 38mm to 50mm, while the 40mm profile provides meaningful aerodynamic advantage without compromising handling in challenging conditions.

Our latest evolution in carbon manufacturing uses an ultra-precise 1k winding process – meaning each tape contains exactly 1,000 carbon fibers.

While our 4th generation process already led the industry in precision, this new narrower tape allows for even more precise fiber placement and creates an exceptionally smooth, void-free structure.

Think of it like building with LEGO® – using smaller bricks allows you to create a more detailed, precise structure. This refined process delivers an uncoated Class-A finish and allows for better gas evacuation during the curing process, resulting in an even more uniform carbon structure with superior compaction.

The rims are compatible with tubeless tires designed for hookless rims. Optimal widths are between 38mm to 50mm
