Shimano Dura-Ace FC-7710 Knurled Chainring Bolt Set
Shimano's world famous FC-7710 Chainring bolts are known to be the toughest and most reliable chainring bolts on the market. Used by professionals athletes all over the world due to their reliability and strength.
The front nuts are super tough and are made from stainless steel, making them unlikely to round or damage. The knurled backing is designed to set or cut into the rear of the crank arm, reducing the need for a chainring bolt spanner. We often recommend epoxy or super-glue under these when installing for added security.... Just make sure not to get any into any of the threads.
We recommend a torque setting of 8nm when setting up these Chainring Fixing Bolts on your crank arm and chainring combo of choice. These are not suitable for use on SRAM Omnium cranks.
