[QUOTE=peterws;19090358]I would check up on your teeth. Now don`t panic, a visit to the dentists isn`t necessary . . .[/QUOTE

Not necessary, I still have all my teeth. most of 'em are in a little box on my desk.
The thing with running a 24t chainring, one does need to shorten the chain &
lower the derailleur. I'm trying to do the rest us aging geezers a favor. If you're
on a laden touring bike a 24/11 is a good general purpose gear for riding
longer with minimal effort. If you dispute that, all you need do is try it.

correction: 24/11 not 22/11 (senior moment, old address), I'm referring to a 42/34/24 crank set.
