SRAM's 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 they’ve elegantly integrated Quarq technology into the DUB spindle, stealthily gathering the data you need to progress.

- DUB bottom bracket adds durability and simplicity
- Waterproof (IPX7 waterproof to 1 meter for 30 minutes)
