Interesting Frameset under £400 ish
As title, I'm looking for a frameset to build up to teach myself more about the mechanics of the bike. The idea will be to build a nicer bike than my basic trek 1.1 I have now. Don't mind what material but the lighter the better if possible, not the end of the world if it's not though. The only other thing I'd like is something a bit different from the normal bike you see about.
