Fireproof said:Look closly at this photo . . . http://www.recyclart.org/2009/03/overkill-chopper/ See where the front chain is close to the frame and it goes to a sprocket ahead of the rear tire? That is a shaft (a "jack shaft"), supported at by bearings at both ends, and it has a second sprocket so a second chain can go to the rear hub. On that bike, the shaft is hard to see because the shaft is black, but there are two chains and four sprockets. A neat trick is to use a three-speed, internally-geared hub as a "jack shaft"! :wink:mattp427 said:. . . what do you mena by "jack shaft"?
Yeah i looked at those last night, thats what i thought it was. But, how could i like make it have gears and like a suicide shifter?
