Here we have a Vintage SACHS EY W7, 6 Speed Freewheel , 13-21T with standard English hub thread 1.37 x 24. Hailing from the 1980s, the freewheel is in great condition for its age. The metal is still very shiny and has kept its colour. The teeth are very square showing little wear. The freewheel itself feels smooth with no grittiness. Overall a very nice component that would be a positive addition to a vintage bike build project. Prior to sale the freewheel has been cleaned and degreased and is now ready to fit.
