It’s the best of both worlds. A light and stiff direct mount chainring with accurate Quarq power measurement elegantly hidden inside the DUB spindle lets you stealthily gather the data you need to progress. So you can focus your attention on the stunning finish of the carbon fiber crankarm. The wide chainline crankset fits in road and MTB bottom bracket standards so frames can fit wider gravel tires.
