Ok after a couple of tries am not having much look in getting my project off the ground i'm trying to build a bike for £100 with all the spare parts i have lying around for commuting and a bit of dirt jumping (a strange combination i know) basically I just need a frame 16-18 " and possibly a fork thinking a BB, post cables etc will set me back about £30 S/H so ive got about £70 for a frame minimum , preferably after steel to keep it real but not that botherd so any recomendations or things have people got for sale
