what is a good combo for the mojave? im thinking about getting a 13 for the front would that work with the stock chain or would i have to get a new chain?

 

will work

 

You might also consider a smaller sprocket on the rear. If you do this, you will need to remove a link. With every step in one tooth on the front sprocket is like stepping down three teeth in the back. My Mojave would hit the limiter at half throttle in fifth, so I put the 13T on the front and it killed the bottom end. I then put the 12T back on and dropped two teeth on the rear sprocket. Now it will still hit the limiter, but not as easy. Also remember that the rear tire size has a lot to do with the gearing also.

 

i have 22's on right now but im waiting for my 20's to come

 

With the shorter tires I would put the 13T on to start with, but don't change anything until you change the tires. Otherwise you'll probably have to change the sprockets again.

 

Thanks for the info, another question are 2.5" wheel spacers for the rear a good idea?
