I think it's 20/33
What is the difference in diameters between 750 and 800 axle?Are the 800 and 750 gears splined the same. What I want to know will the 750 gears work on an 800 and vice versa? I know the axle is larger diameter on the 800 so I'm thinking the bottom gears may be different. A lot of guys are always looking and asking me for gears and they are getting hard to find. I was also thinking that for racing the 92 gears and chain would be the best to use because they are lighter. What about running a 93 bottom gear on a 92 with 92 chain and top gear?
