There are many bikes out there, but maybe they aren’t quite right, and you want to build your perfect bike from the ground up, choosing your dream frame and the best components. This category has frames and frameset with forks to get your build started. Choosing the right frame is very important as it will decide whether you can run thru-axle or quick-release wheels, whether you will choose disc (flat, post, or IS mount) or rim brakes, as well as which bottom bracket standard you can use. It is important for MTB and Dirt frames to check what front suspension will work with your new frame; choosing the correct travel fork is critical for the bike to work as it is designed. There are also several wheel sizes available, with 26” still being popular for super-strong dirt bikes to 27.5” and 29” wheels for most modern bikes. Some frames work with both sizes, giving you options to change the wheels depending on your preference.
