ns have some frames, marked “DIrt” or “PArk” , the dirt one is longer but not by much, canyons’ dirt frame is longer than both of them, santa cruz do two different lengths in their jackal frame, the bigger one is about the same as Canyon’s and they recommend it fro guys over 5’9, but lots of bigger guys prefer the smaller frames anyway, i don’t think it makes a massive difference since you don’t sit down and pedal.
