Designed in collaboration with ENVE's cross-country racers, the M525 Industry Nine Hydra 29in Boost Wheelset is designed to soar down the singletrack whether on the race course or the local loop. They feature a carbon fiber rim construction to bolster strength and stiffness, while 24 featherweight spokes let these wheels accelerate with impressive speed. The 25mm internal rim width finds the balance between traction and a fast-rolling feel, while Hydra hubs from I9 provide instant engagement that we love for lacing up techy climbs.
