Why We Like The DH 27.5in i9 Hydra Wheelset

Designed for the demanding nature of modern downhill tracks, the Reserve DH 27.5in i9 Hydra Wheelset delivers bomber durability that’s intended for racing and DH riding at the highest level. The 32h spoke count combined with Reserve’s burliest carbon layup provides durability that’s been developed in collaboration with Santa Cruz’s downhill racing team. The reinforced rim bed provides further impact resistance, and these rims are rated for e-bike use.
