I just nabed a Pennys 3-speed bike off the street. They were throwing it away. I got it mostly for parts but the 3-speed sparks my interest. It has drop handelbars (turned around though ), 26in wheels, Shimano 3-speed hub (333 F). The decals say BMA/6 certified and Slight Weight. Couldn't find a cereal number or any stampings on the frame. (only looked under the crank) Has a rear rack that has the flip up hold down. Not rusty and seems to be in good shape. Tires are flat and the front brake is always on so I have not ridden it yet.
From my research so far the shimano hub dates to 1960-70s. It has a thumb shifter, friction I believe. So any information on this would be appreciated. Is this worth fixing up? How would I clean the 3-speed hub? Thanks.
