Crupi has taken a new approach to chain ring bolts. With all the chain ring & 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
• Weight = 0.31oz
