240 DEG 90 DF Micro Spline Super Boost Rear Hub

DT Swiss 240 DEG 90 DF Micro Spline Super Boost Rear Hub is a precision-focused MTB rear hub for riders who want near-instant power transfer without sacrificing long-term reliability. The DEG high engagement freehub system uses simultaneous full ratchet engagement to spread load more evenly than pawl-style systems, helping the hub stay consistent under hard pedaling, technical climbs, and repeated impacts. With a very small idle angle at the cranks, acceleration feels more direct and efficient—especially when timing pedal strokes through rocks and roots.
