Overview
About this bike
The Monocog is a steel single-speed 29er for the ultimate in simplicity. A chromoly frame and fork makes for old-school style and gives you the smooth ride quality that steel is known for. Durable, double-wall 29-inch wheels let you roll over obstacles, whether you are on the road or cruising on trails. Tektro mechanical disc brakes and a nice, wide 740mm riser handlebar round out the package for great control and a comfortable riding position. This fully rigid mountain bike is at home on trails, gravel roads, and even pavement to give you a versatile ride that's plenty fun on the singletrack.
