Actually all the sizes of the Cowan HT have DJ geometry, but the bigger the frame gets, the longer the tubes get. All of them. This is good news for tall riders, because people with long legs can't ride 13" frames, even if the top tube is sized appropriately.
seriously, your kidding me right! omg dude u try and do a nfcc on the bike, the damn toptube is wayyy too high for a friggn dj bike, the seat would get in the way all the time too, u gotta think of function of wht its designed to do lmao
