Are these any good? I see I can get a 12 tooth front sprocket for my Raptor for $9...that's awfully cheap. I can also get a 11 or 12 tooth Moose sprocket for $17. Which will last longer?

Will one tooth make a big difference or should I go down two? I ride lots of tight trails and will essentially never hit 5th gear.

 

I never had a problem. 1 tooth does make a difference.

 

1 tooth makes a big difference...i have a 12 on mine right now, cost me ten bucks even for it, had it for about 3 months and i ride haard. Don't go 11, youll have to modify your chain guides and things of that sort. I say go with the 9$ 12 tooth!
