Crupi has taken a new approach to chain ring bolts. With all the chain ring and crank choices available today, it is really difficult to find chain ring bolts that fit properly for all combinations. Our 15 piece kits offer 2 different sizes of backing bolts so you will never have that problem as ours will fit any combination! A better quality chainring bolt which is CNC machined from 7075 aluminum. The larger size backing bolts also have an Allen slot for ease of installation. These are all you will need to insure your chainring is properly secured to the crank
Kit includes 5 male, 5 short female and 5 long female bolts for a total of 15 pcs.
