Hey guys So I have a 26" dirt jumper which is basically a bmx setup.and I can't figure out the gearing and don't want to waste money on trying multiple setups. So on my bmx I have 28t sprocket and a 9t driver and on the dirt jumper it's a 27t Sprocket with 9t driver. It was 27-12 but it was too easy and now it's too hard Just wondering if anybody knew a formula to calculate 26" to 20"?
Oh thank you. This is what I couldn't find. According to this calculator I'll. Need a 21t sprocket on the front. That's pretty small. And will be difficult to find aha.
I think if I went a 11t driver on the rear it should be pretty close.
