25mm Shoulder Bolts
If you have been using the "china" idler pulleys, you likely have 20mm shoulder bolts, and should be able to continue using them. If you are upgrading to gates pulleys and/or magnum pulleys, you will need 25mm shoulder bolts. These are sold by the piece, so if you need some for your Railcore, you will need 4 of them.
