DT Swiss 240 EXP Straightpull Road Rear Hub Swiss Precision Where It Counts Most Road and gravel wheel builders who want the lightest, most serviceable hub at the 240 tier have one clear answer. The Ratchet EXP system fuses the ratchet and threaded ring into a single piece, cutting parts count and weight without sacrificing the full-face engagement that makes the 240's power transfer feel so immediate. Straightpull spoke lacing keeps flange geometry consistent and spoke tension high, and the redesigned end caps come apart without tools so a trailside service stop stays quick. Whether you're building up a race-day set or a fast all-rounder you'll ride every week, the 240 EXP earns its place at the center of the wheel.
