The sleek new MRP Race Axles give you increased rear end clearance - especially useful for those who ride tight, technical trails. In some cases, our Race Axles save upwards of an inch (~25mm). Additionally, they weigh in anywhere from 20-50% LESS than the common QR-style thru-axles (Shimano E-Thru, DT-Swiss RWS, and Syntace X12).
