Why do they curve the toptube upwards giving less clearence. They should curve it down. Not only would it give your balls more clearence, but in my opinion, it would look better as well.
Dispite common beleif the pressure points for the geometry of the shine, Straight may not be the best option! By bowing the TT your giving it more resistance to bending in on itself on hard landings?.... And its looks badass
