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!
CNC machined 7075 aluminum
The larger size backing bolts have an Allen slot for ease of installation
Kit includes 5 male, 5 short female & 5 long female bolts for a total of 15pcs
