Our 43/30T chainring combo combined with a wide chainline increases tire clearance while providing ideal gearing for venturing off-road. But gravel riders need power measurement too, so we’ve elegantly integrated Quarq technology into the DUB spindle, stealthily gathering the data you need to progress.
