Look around this site, there is a seller here who sells a sprocket to fit your disk. Easy as pie.

You are probably going to lose the rear disc, as sprocket and disc will not fit. The good thing is as toy stated there is a vendor that will make a sprocket for you that will bolt where disc is now. Makes it alot easier to get chain aligned. Just look to the left.....

Maybe "kings" can custom make a sprocket & disc brake all in one!!!
(like Exile Cycles)? That would be BAD ASS!!! (^) (c)

Or with a jackshaft kit you won't need to mess with the stock brake set-up.

three quextions-

1.) When will they be market ready?
2.) Final price with shipping?
3.) Will it eat a cheap W-Mart Moondog type derailuer?

1) Mid-End of June.
The design is locked in. I'm almost done with the installation manual. We have almost all our suppliers locked in and lead times down. We need a couple more first article parts, but it's getting very close. We probably announced it too soon - sorry.
2) $199 plus shipping UPS depends where you live.
3) I doubt it. I purposely have been doing some fairly harsh shifts under power, no clutch, with my Shimano (yeah I know), and it hasn't exploded. The twist shift is the bee's knees, it's pretty easy to have the coordination to get off the throttle to shift.

Just so you don't get confused, the sprockets are out now, and bikeguy was talking about a jackshaft, which would bring your chain over to the right side of the engine.
A really cool idea , by the way.

A jackshaft brings everything over to the right side of the bike and you can hook the chain to your peddles. Now you could use your gears and fly. try searching it out on this site, I'm sure I saw a really cool one pictured here. It may have been Pablo. You could also search his posts out by clicking on his profile/name, I think.
