Wow guys! This is cool and I hadn't seen it as going to this extent. Including bicycle parts, engine parts and maintenance/repair. So am thinking 3 portions. Bike, engine and mechanical? Or an all in one and adiabatically listed? Could do it as a thread and when some one comes up with a new or some thing to be added the first post, the OP (Original poster? hehe, I was never sure of that one) Just adds it in the right place?
the gap thing had me screaming way back. inches, metric....arghhh.
