. . . and be sure you are getting the right size. They come in different diameters, different lengths and different angle of the flat part. The diameter is the absolute critical dimension. Coter pins are soft metal, so if they are too long or the flat is wrong, you can (usually) fix that with a dremel, cutting attachments, and grinding attachments. Takes patience, but I've made it work, and I am nowhere as mechanically gifted as many here. And do0n't ask me how I found all of this out.


BTW, I hate cottered cranks. Only my Eroica bike has them, and only because everything is spinning well and I don't want to mess with it this close to the ride. But I already have the cotterless replacement crank and BB in hand, and they will go in very soon after I get home.
