Ratio's

I didn't know that. I thought that more teeth on the big ring would have made more of a difference. I think I will try a 17 tooth cog on the back.

Thanks for your help.

hang on a sec am i missing something... doing that would make you spin more.

pj was saying is that changing the rear cog has a greater effect than the front.

Spock is saying go 15t on the rear would make a difference to you spinning on the down hills and make it slightly harder to pull away.

Shin say go 15T
