When the lowest gear isn't low enough

Or that they have a bigger cassette in the back. - Count the number of teeth on the smallest/largest cog: what's yours-11-23?? what's theirs? a 12-25 or 12-27?
I don't really think spin class is needed to teach you better spinning.

Hey chaps
Thanks for all your replies - and yep to those in Perth, it was Reobald hill I was going up !! Nightmare..

I've just counted the number the teeth I have 11-23.

What does that mean then?

Thanks
