Our 43/30 chainring combination and wide chainline improve tire clearance and ensure ideal drivetrain performance for off-road racing. But gravel riders also need power measurement. That's why Quarq technology has been elegantly integrated into the DUB spindle, discreetly collecting the data needed to progress.
