All BBInfinite Ceramitech pulley covers come with our offered pulleys. All Shimano and Campagnolo systems use 5mm bolts to secure pulleys into rear derailleurs. All Sram road systems use a 4mm bolt to secure the upper pulley and a 5mm bolt for the lower pulley. The 6mm is for the upper on Sram road 1X systems.
