Anyone know what’s going on with this?
Work at a bike shop that deals with a lot of cool old donations. This came in and I’m having trouble finding any info. Look rear hub ano red, it’s got that plastic jawn comin off the non drive side. Feels like it has some “clicks” kinda like a dynamo interface. Hoping some nerd or old head could point me in the right direction. Thanks! 2211 is stamped on the plastic.
