Gearing with 20" tires

[deepcj7]

I have 14/38 on my CRF right now...the build will be completed in 2 weeks, so I haven't really run the thing in real world conditions yet. For XC/GP, what are you guys running? I'm considering 13/38.

Thats huge tall gearing, how do you even start?!:D
In the sand, and on the MX track I run a 13/42 with 20's I am looking at a 13/38 with 22's when I run a whiplash/desert series over here in AZ.

I have only run it on the street so far and it was fine. It was during mock up and I was just checking to see if everything ran right. Well thanks, I guess I need some new rear sprockets.
