smaller ring for touring??

[cindysue]

I like my 28x34 for the 17% grade (4 knee ops! ). I'll run in 28x18, 21, 26 the rest of the time (on North Gate). I think speedo Kim has a lowest gear of 30x27. V is running 24x30 maybe?

my head is spinning. I just don't understand the difference between one number and the other. Maybe I'll give Chris a call after Friday.........

Thanks all.
