Hi,
I am currently working on my first ever bike build, it's going to be a Gazelle AA Special single speed for going around London on. I have already made a fair few mistakes!
I have just discovered that the Camapagnolo headset I have fitted is probably not the right one. I have stupidly fitted the cups only to discover the crown race is too small to fit over the fork. After researching a lot I have discovered that a JIS crown race is .6mm wider than the ISO. I just want to make sure I have this right before I waste another £50.
(If you want to know the other things I have got wrong; I bought a bb with too long casing and a crankset in which the chain wheel was bent)
