I'd ask in Mechanics, but I know the info I want is probably here.
1-already answered, I think by irvi...: How do you get the FD clamp from a Suntour Superbe off the seat tube? Mine appears locked on. The mounting bolt has a Philips head engraved in it, but it's got a ring that sort of seals it to the clamp.
2-I've come across a nice Campy rear wheel, with a 7-speed cassette, lock ring and all. It's 130mm, but won't accept an 8-sp cassette. Is the freehub interchangeable?
3-Can you lace a 36h front hub to a 28-hole rim and live to tell about it?
