There are lots of 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 framesets 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. For road and gravel bikes, there are also many wheel standards available, from narrow 700c triathlon wheels with tight clearances through to gravel bikes that can fit 700c and 650b wheels with chunky tyres.
