Features

Revolutionary Rim Layup Technology

Our proprietary ultralight layup process sheds weight while maintaining impact resistance – delivering a stronger, leaner gravel rim without compromising durability.

Advanced D91 hubs with 45T star ratchet system

The advanced D91 hubs feature a 45T star ratchet system that replaces the 6-pawl design of the D21 hubs, and the Shimano freehub body features a unique design that reduces weight while maintaining structural rigidity, making it approximately 90G lighter than the D21 hubs.

Aero & Weight Savings with Sapim CX-Ray

Sapim CX-Ray spokes reduce wind drag and weight, paired with Sapim Secure-Lock nipples to prevent loosening under vibration.

UCI Certification for Race-Ready Confidence

G27 is fully certified by the UCI, giving riders the confidence to use it in sanctioned races and elite-level events.
