i'm running a 13/44 combo work good in the woods and mud where i live. running 22
inch mud tires. had goodpower with stock gearing but like the lower gears better, might get a 12 tooth front,just to see how it works
12/40 all day here. Might drop a rear tooth but i race awrcs (sorta like gncc) and it pulls great through all 6 gears. And i got 20's sitten in the back
i run 14/40 with 20's. i lost alittle acceleration but the bike pulls through all 6 quite nicly. im planing on getting a set of 18's and goin to a 38 in the back. i go on alot of late night runs
