To allow that singular focus, we've engineered the DUB™ spindle to be the one true unifying component. One oversized spindle to work across every bottom bracket standard. For better crankarm compatibility.

For better protection from the elements. For longer-lasting performance. To be stronger, smoother, simpler. Now, back to the ride.
