    I'm looking for a freewheel adapter for a square taper spindle that can accommodate two freewheels. I've seen threaded cranks but they only accommodate one free wheel http://sickbikeparts.com/catalog/product_info.php?cPath=21&products_id=35. I've attached a picture of what I'm looking for. I'm starting a new project on a tandem bike where the motor chain attaches to the rear passengers bottom bracket. easy shift kit. :idea: any help you can give would be appreciated. peace

    That's exactly what i need. where did you get the parts?
     
  4. The freewheel adapters, 5/8 keyed shaft, & sprockets are from Staton-Inc. The bearings are fit to the European bottom bracket adapter by dremaling the threads to fit tight. Dave Staton also sells threaded bearing holders. Check out his Giant Stilleto kit. I have used those as well on another bike. Here are some more pics. This jackshaft can be driven from either side. I actually first built it to drive on the right side. It now drives on the left.
