The bigger the wheel, the easier it is to roll over obstacles, so it's no wonder so many riders are joining the 29er revolution with Redline's Monocog. This great singlespeed features 29-inch wheels as well as 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. And, with its reliable Alex rims, powerful Tektro linear-pull brakes and a sweet Kore handlebar, the Monocog is a super bike for people who want to experience the fun ride of 29-inch wheels.
