Standard size of mountain bike cup holder
Height 180, then the best operation of the 19 car, or 17 frame a little bit smaller, does not look good. One is riding up force angle, as well as body posture and so on are not appropriate, 180 riding a 19 frame or is considered appropriate, hair feeling there are riding and so on are appropriate! So it is still 19 of the car, it will not be inappropriate, unless you like the small frame, only 17 of the frame!
