1 tooth down

[solman]

I just added two to the rear only.  It already has good torque, but I wanted just a tad more.  Adding two to the rear did the trick.  I also didn't want high rpm's while cruising.  BTW, if you feel the need to keep adding/subtracting sprockets to get more, then maybe you need to upgrade to a 1216.

From what I have read adding 3 to the rear rather then dropping 1 from the front provides better geometry more load to the rear wheel, where as dropping 1 from the front although achieving the same as far as ratio, put more load stress and ware on the chain. But hell that probably true for racing not GP riding.

Dropping one tooth in the front is the same as 3 in the rear.  I added two in the rear and like the change.  It gave me a little more low end and little effect on the cruising side.
