So I found the old mountain bike that I got for my 12th birthday (12 years ago!!) in my attic.... I want to turn it into a SS but I do not know what to do about the wheels... it obviously had MTB wheels on it, and it has cantilever brakes.... so a 27" isnt going to work out (tried it today...) anyhow, WTF??? What are my options here for wheels/ brakes.... any info would be RADICAL!!! Thnx
