This is Critical Cycles brand new fixed-gear/single-speed bike. We want you to choose how you ride, which is why we've built this baby around a flip-flop hub. Ride fixed or single-speed with a freewheel. Our bikes come installed on the single-speed side, but you can quickly change the orientation by removing, flipping, and re-installing the rear wheel. These speed demons come equipped with two brakes to ensure your safety, 30mm deep-v rims for a softer ride, and KMC chain for ultimate reliability. Just because we've built this bike to be kind to your wallet, we haven't compromised on the quality of our components or the reliability of our ride.
