Hi all, I'm hoping for a bit of advice. This has probably been covered many times and I apologize if it has. I have been given a Raleigh Record Sprint, she's in fairly good condition, just in need of some tlc! (left in the garden for three years...) Its only a 12 speed and was thinking of getting an 8 speed cassette and some new wheels, to keep up with my riding buddies. Obviously the drop out spacing is 126mm and would need at least 130 to get the set up that I want. I read an article on Sheldon Browns site about widening the rear drop outs and wondered if anyone has tried it? Or would I be better taking it to my lbs and getting them to do it for me? I'm completely new to this and want to be sure before I go and ruin the bike!
