Simplicity meets rugged refinement in the Redline Monocog AL. A lightweight aluminum frame with a tapered head tube partners with a rigid carbon fork for fun, lively performance on every type of terrain. Durable 29-inch Alex rims are wrapped in Schwalbe’s Nobby Nic tires to give you a fast-rolling combo that rips on race courses and backcountry trails alike. The 32/18 Truvativ drivetrain has the right gearing to tackle everything in your path. Finished off with Shimano hydraulic discs, Crank Brother’s Cobalt components, and a sweet Fizik saddle, the Monocog AL achieves exceptional single-speed sophistication.
