This question has been asked elsewhere before but I am still not sure of the answer. I am trying to replace a broken 10-tooth pulley from Simplex (off an old Peugeot bike). It's rather similar to Suntour from an old Schwinn. I know I have no problem using the Suntour in place of Simplex but then the Schwinn is without a pulley. Since both Simplex and Suntour are difficult to find nowadays, is there a cheap $5 Shimano pulley that can take its place? The pulley measures 1 cm in thickness, about 4 cm in diameter and it's hub is 6 mm. I do not need the bolt. Also, it does not have to be an exact match since friction shifter is a bit more tolerant than index shifter, I think. Thanks for your help.
