Okay Guys. I am looking for your expertise please. I have a retro Profile crankset that I want to fit to a Euro BB shell and use a smaller chainring/gear, and get rid of the spider.
So, firstly, can I get a Euro BB for it, and what should I get?
And secondly, what chainring/gear can I use on them?
This is my first step in this direction, so thanks in advance for your help
