where did you get the 56 tooth ring?

BB should be fine if it a square tapper.

Not sure about the ramps, I may have the same problem myself as i am still waiting for my 56t to cross the atlantic. You should need to do anything so far as I know,but it may be woth taking them of to reduce the chance of the chain getting jammed between then and the Mezzo chain guild should the chain come off. Please keep me in touch as reguards how you find the IHG. Mezzo need to offer a quality internal hub,a cespro or a dual drive option to make this upgrading unnessary.

I have put slick kojacks tyres on my sportier bull bar version, but due to the bad weather recently I have opted to use the more standard Gold 3X7 Mezzo more lately. The more compact faster fold suits shopping that requires more folding easier. I have adjusted the gearing and it changers really reliabily and there is no click box to worry about as I go through anti motor bike stills.
