cheers mate,think im just going to go with a 26". now wether to build or buy complete. i havnt got a massive budget as im paying out a lot at the mo, and there doesnt seem to be many cheap bikes about,and the ones that are,arent what im looking for. But ive seen a few cheapish frames and loads of cheap parts,every part id need to build one infact,but its knowing what goes best with what,like what rear single speed sprocket is best to use with a front freewheel,and how many teeth on each? does any crank go on any bb?and does any bb fit in any frame?any headset fit in any frame? etc etc lol! sorry for all the questions and that mate just would want to do it properly,dont want to start buying random parts if there not going to fit together!
