Asymmetric undulating carbon disc brake wheelset. Built with a Toray T800/T1000 composite structure, Sapim CX-Ray spokes, and CNC-machined hubs with centesimal tolerances to stabilize handling under crosswind airflows.
The Drive Helix SS series is built on an undulating, variable-height rim geometry inspired by the tubercle effect to neutralize crosswind drag. Engineered from a blend of Japanese Toray T800 and T1000 carbon fibers bonded with a specific resin, this wheelset delivers lateral stiffness validated beyond the requirements of UCI impact testing.
Key Features
UNI carbon structure combining Toray T800 and T1000 high-modulus fibers to minimize peripheral mass.
Asymmetric undulating profile with a wider front external width (31.8 mm) to optimize aerodynamic airflow.
Bladed steel Sapim CX-Ray spokes with an average unit mass of 4.4 grams, ensuring high tension and direct torque transfer.
Aluminum Surface hubs machined via 5-axis CNC digital control, featuring a star ratchet engagement system.
TPI steel bearing seats calibrated to a 0.02 mm tolerance to eliminate play and mechanical rolling resistance.
Compatibility
Optimized for 700 x 28c to 700 x 30c tire widths. Compatible with Shimano HG, SRAM XDR, and Campagnolo freehub bodies. Disc rotor mounting via standard Centerlock interface. 12x100 mm front and 12x142 mm rear thru-axles.
