Cool bike. Would you have a list of components for the drivetrain + the year the bike was built by BF? Looking to convert my SRAM DualDrive setup to a regular one.
Thanks.

When you say 'regular one', do you mean 'with multiple front chain rings and front derailleur" ?

If so, the technical questions to ask are:

  1. Do you have a derailleur hanger brazed on above the crank?
  2. How wide a gear range are you hoping to achieve?

The philosophical question to ask is:

  • What are you trying to change?

Is the DualDrive too heavy? too strange? broken? restrictive?

Sram abandoned the 3 speed + cassette hubs,  Sturmey-Archer continues.
Common rear hub 135 wide  ... will do ...  even disc type no need to fi a disc,,
Shimano alfine & chain tensioner , & 1 cog  is practical...

A free hub wheel built  without the Internal gear part may be fine  irf ratio range demands are less..
