So I have a few questions about this bike if anyone can answer them. I recently picked up this bike from a used bike place, the wheels on it are 27" but I'm almost possitive it should be 700s am I wrong? Also is this bike made of steel? I want to get my fork corrected because the privous owner obviously got into a front end collition of some kind. Is it possible to bring it to a shop and have it corrected and it be safe???
