Level Hub Respacing Kit
A LeVeL respacer kit is an extremely useful purchase, since the appropriate kit will enable you to migrate your 120 LeVeL rear hub onto a 135mm bike, or vice-versa. The term 'spacer' doesn't do justice to what is actually a substantial piece of precision machining. But this stuff is hard to explain!
