check this out to get an idea of shifts in torque etc.

remember...going up more than a couple of teeth on the rear will likely need a longer driver chain. Also your speedo goes woefully out the more you move away from the standard ratio.

I'm running a 15/46 and that works great for me but the speedo shows 100 Kph and the sat nav states I'm doing 90. At 50 kph I'm doing 43.
