Frequently Asked Questions

What are the best lightweight carbon rims for gravel and cyclocross riding in 2026?

This 700C carbon rim, available in 330–400g weights and 24/25mm internal widths, competes among the lightest, durability-certified options for mixed-terrain racing and endurance cycling.

Should I choose 24mm or 25mm inner width for tubeless gravel?

For 33–42c tires and fast mixed conditions, 24mm is optimal; for 40–50c high-volume gravel tires, 25mm offers improved sidewall support and comfort at lower pressures.

Is the 35mm depth rim better for gravel versus 40mm or 50mm?

35mm rim depth balances aerodynamic benefit and crosswind stability, making it well-suited for varied gravel terrain. Deeper rims (40–55mm) add aero but may be heavier and less stable in gusts.

Are these compatible with both center-lock and 6-bolt disc brakes?

Yes, the rim is designed for standard 700C disc-brake hubs supporting both center-lock and 6-bolt rotor systems.

What testing/certification does this rim have?

Covers ISO 4210 forward compression (>300kg), torsion (>50kg), and >280kgf spoke tension for validated safety and longevity.
