ATEM5 Carbon Wheelset

ATEM5 — Engineering Before Speed

ATEM5 is our latest high-performance carbon wheelset, developed with one philosophy: Engineering Before Speed.

Built from premium Torayca T800 carbon fiber, every rim is manufactured using our Module Hole Process (non-drilled spoke bed), creating a lighter and stronger rim structure with improved impact resistance.

Before assembly, each rim undergoes multi-directional impact testing at 10 impact points. While the UCI impact standard is 40 J, ATEM5 successfully passes our own internal standard of 95 J.

Each wheel is then hand-built by professional wheel builders using carbon spokes and our precision ratchet hub, with every spoke tension individually balanced for maximum reliability and performance.

Designed for both Road Bike and Gravel Bike, ATEM5 is optimized for tires ranging from 28 mm to 50 mm.

Built to race. Engineered to last.
