Wink Re: Does a gear hub can hold a 212 predator?

I have a 212+cc Predator (first generation) that I have been racing for over 5yrs. now and it's gone from single speed TC at 10hp to 2 disc cent. clutch at 26hp.

Either way gears have not been needed for this application but a jack shaft is required of course. Currently running a gear ratio of 11.11:1

The primary gearing is 12t on the Vortex clutch to a 25t sprocket using #35 chain and the secondary is 9t sprocket to a 48t sprocket on the hub with a #41 chain.

Tried and true... I've won many races using this setup.

Is that seat tube sleeved?

Not sure what you mean by sleeved? However, the seatpost is the whole length of the seat tube right down to the bottom bracket.
