I scrubbed it by hand, used wd40, green scrub pads, wire brushes, and a pick for stuck dirt in the tight areas

4/9/2020 4:19am Have just counted the gearing on it. And it’s 12-48 and have had a look at the stock gearing and it’s 12-51. That’s pretty far off from stock, thinking of going upto 12-50. Is that a good idea? What are other people running?
