[MENTION=392491]xscottypx[/MENTION] That's a -big- ratio to start with. Not much smaller than my 48-15.

I'm avoiding even numbered cogs for more even tire wear. 18t is 5 patches isn't it, on a 48? Whereas 17 is 17 and 19 is 19. I'm not a skid demon by any measure but I do enjoy it and would like my tire to last.
