The simplicity of a singlespeed with the benefits of a 29er explain why Redline's Monocog is so popular. This great ride features a nimble-handling chromoly frame and fork that make it perfect for off-road rides and urban commutes, too. The fat, 2.2-inch Kenda Nevegal tires mean that you'll stick to pretty much anything. The drivetrain consists of a lightweight SRAM crankset with a 33-tooth chainring and a 20-tooth cog for a great all-around ride. With its reliable Alex rims and powerful Tektro linear-pull brakes the Monocog is a stellar bike for people who want to experience the fun ride of one gear and 29-inch wheels.
