Default Re: A new shift concept for the engineers....

heres a link to a thread i started awhile back on flip flop hubs,
the 3 speed jack shaft hub i did on my silver bike is working great, i still have that bike, but it's only running a gx35 cc motor, i think it would hold up to a HT-china girl but not a 5 horse or harber freight, anything like a morini would kill it quick.
with a flip flop hub you should be able to take a cassette apart, flip the sprockets so the tilt of the teath are going the right way and attach it to the left side of a flip flop.
