The 85 like the 50mm are a monoque design (teardrop shape, whirlpool side blades). Basalt fibre (volcanic rock) braking surface. These rims are superior in design, side wall strength and aerodynamics.The rim is manufactured from 100% 3k high modulus carbon fibre allowing the spokes nipples to be hidden in the rim. The alloy hex head nipple then near doubles the contact area. Compared to other products, a Zipp rim for example, this makes the wheels stronger and more reliable in this vulnerable area. It also improves the overall wheel aerodynamics.

- Maximum Rider weight 110kg
- Wheel set weight 1590g
