12 front, what size back for rappy?

I run a 12 tooth front and stock rear. I want to gear down more so I was thinking going 42 rear. What do you think? would I have to change chains to do so with either 12/42 or 13/42? thanks

you could run 12/42 with stock chain and could maybe squeeze 13/42 on there why you want to gear down[img]i/expressions/face-icon-small-confused.gif[/img]

13-42 wouldn't be as low geared as 12-40. If you're gearing down from 12-40 you would have to go 12-41+ or 13-44+.

Hayseeds dead on. I am running a 12-41 and it is perfect for anything but long, long straightaways. The only problem I had was clearance between the sprocket and my aftermarket skidplate!

Why would you want to be geared so low?

12:41 will definetly have you where you seem to want to be.

straight line sand climbing is why I want to be geared so low, top end isn't as important as climbing ability. I rarely rev out 5th so that isn't as big a deal as good pulling
