Hey again guys and gals,
The picture above resembles a hub, was wondering what that danglely thing is that hangs out the right-hand end - what is it there for?
Also why are there gears in the hub? Dont the shift gears change the torque/speed for the bike? Or is this not entirely true?
Thanks,
Aaron.
