Product Description

The Cobalt 3 from crankbrothers are elite-level aluminium wheels for XC trail riders. They feature a unique wheel design that is based around principles of strength, stiffness and acceleration. The unique wheel design distributes mass closer to the hub for faster acceleration and deceleration.

The wheels are tubeless ready out of the box, as they feature no holes on the inner rim bed. They are incredibly strong thanks to their Twinpair spoke technology – designed using the strongest shape in construction, the triangle, to maximise strength and stiffness.
