Did you feel that? Your bike just got faster with Crank Brothers' Cobalt 3 27.5-inch Wheelset. These flyweight wonders boast tubeless-compatible aluminum rims that keep the weight down to a feathery 1,650 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. Plus, the extended aluminum nipples simplify the truing process and optimize wheel stiffness.
