Built for aggressive enduro riders who demand the fastest engagement available, this wheelset pairs Stan's most durable tubeless rim with Industry Nine's iconic Hydra hub — delivering 690 points of engagement and a 0.52° engagement angle that puts power down immediately out of every corner.

• Stan's Flow EX3: 6069 alloy, 30mm inner width, Tiebeam triple-cavity design for impact resistance
• Industry Nine Hydra hubs: 690-point engagement, 0.52° backlash, available in a wide range of axle and freehub configurations
• Tubeless-ready with Bead Socket Technology for a reliable, low-pressure seal
• Boost 110x15mm front / 148x12mm rear as standard; other axle spacings available on request
• Handbuilt at Tune Cycles — spoke tension set for your riding weight and style

The EX3 rim's Tiebeam inner bridge resists the sidewall folding that can cause air loss under big impacts, while the 29mm inner width optimises casing support for 2.3"–2.6" tyres. It's proven at World Cup DH and EWS level and is an excellent choice for eBike use given its 6069 alloy construction and robust profile.

The Hydra hub uses six pawls engaging simultaneously with 115 teeth per ring for its extraordinary engagement. Available with Shimano Micro Spline, SRAM XD, or HG freehub bodies. Specify your rotor mount preference (6-bolt or Centre-Lock) and wheel diameter (27.5" or 29") when ordering.
