Been looking at the sturmey archer front and rear drum brake hubs, namely the x-rd and the x-fd. Has anyone seen these hubs modified for motorized bicycles. I'd love to get one if someone can steer me in the right direction.
i have the 70mm fd frt on 2 of my bikes.
didn't like it at 1st, they don't work well until seated/broke in.
after several miles they just get bettter.
the shoes are real thick and the bearings are sealed.
gives the bike a nice clean look and should last a lifetime.
