This goes off a previous question:
Suppose I want to replace my solid axles with quick release skewers on my fixed gear bike. Yes, I am aware that this isn't necessarily recomended, but done right it should be fine (i.e. enclosed cam qr skewer, chain tensioner like surly tugnut).
The spacing in the rear 120mm, what kind of quick release skewers do I get? I can't seem to find any with 120mm spacing. Is it simple to buy one that is ~130mm and shorten it? How do you do that?
