'brifter' is f'ing stupid
That would be the Shimano free hub that came on the hub. No one else makes them for Shimano hubs. It should be compatible w/ the 6600 and 6700 free hubs. They're all basically the same. It's not compatible w/ 6800.I need to replace the freehub on my 6500 hub again. Something cracked internally. What is the burliest freehub available that has the same mating interface as my 6500? I know at some point they changed it...
