Quality wheels at an exceptional

"Quality wheels at an exceptional cost! Crank Brothers knocked it out of the park with these wheels. Out of the box these wheels look and feel amazing! Smooth finish, pre taped for tubeless set-ups, and they spin so smooth. Beading the tires was a snap, even w/ (Cush Core)inserts. On the bike they roll super well, and very compliant. Can't wait to get a full season on them!."

— Dave H. (5/5)
