The Durham mountain bike by Mongoose was built for rad off-road excursions. The Durham features a lightweight aluminum frame and suspension fork that's ready to take on the trails. The 21-speed trigger shifters provide effortless gear changes, while front and rear mechanical disc brakes deliver superior stopping power in all conditions. Alloy double-wall rims add lightweight strength, and 2.3-inch wide mountain tires provide stability and grip. Plus, the tool-free adjustable seat post makes it easy to fine-tune the fit.
