When you're pushing the pace up a steep climb or sprinting out of a corner, you don't want anything holding you back. That's why Crank Brothers makes the Cobalt 11 29 Wheelset. These flyweight wonders boast tubeless-compatible carbon rims that keep the weight down to a superlative 1,550 grams for the set and they boast machined aluminum hubs with sealed bearings that feel like they'll spin forever. The spokes connect at a vertical rib, thus eliminating the need for spoke holes in the rim to enhance durability and make tubeless setup incredibly easy. Plus, the extended aluminum nipples simplify the truing process and optimize wheel stiffness.
