ERE Research Tenaci GA40 Aero Carbon Gravel Wheelset: Aero Advantage Meets Gravel Toughness

Unleash blistering speed on gravel with the ERE Research Tenaci GA40, the pioneering aero-optimised carbon wheelset designed specifically for high-performance gravel racing and fast adventures. Developed in collaboration with aerodynamics legend Paul Lew and proven in UCI Gravel World Series victories, these wheels deliver real-world aerodynamic gains, exceptional stability, and rugged durability - making them the fastest gravel wheels for riders who demand an edge.

Featuring a 40mm-deep unidirectional carbon rim with ERE's first hookless design, the GA40 excels in wind tunnel-tested efficiency, generating forward propulsion at common yaw angles while maintaining superb crosswind stability. The wide 26mm internal rim width supports tyre widths from 36-54mm (up to 58mm max), ensuring low pressures for superior traction, comfort, and impact absorption on rough terrain, without sacrificing rolling speed.

Built around the in-house ERE Iona S hubs - featuring SKF sealed bearings, a reliable 36-tooth star-ratchet system (upgradeable to 54T), and Torque 2 directional flange design—these hubs provide lightning-fast engagement, smooth rolling, and bombproof reliability in wet or demanding conditions.

Laced with 24 straight-pull Sapim CX Delta/Sprint aero spokes front and rear, the wheelset achieves an impressive weight of ~1,549g a pair, balancing lightweight responsiveness with a generous 140kg rider weight limit.

Disc-only with centre-lock mount, tubeless-ready (hookless-compatible tyres required), and backed by ERE's lifetime warranty plus crash replacement programme, the Tenaci GA40 is race-proven and adventure-ready.

Key Specifications:

  • Rim: Unidirectional carbon, 40mm depth, hookless tubeless-ready
