Kogel crank fixing bolt Shimano, long, blue
Looking for another way to increase the durability of your drivetrain and customize the look of your Shimano crankset?
The fixing bolt for Shimano cranksets, made from T6061-T6 aluminum alloy, sets the axial load of the bearings and holds the arm in place, while you tighten the crank bolts to the correct torque.
Choosing the right length
Short: compatible with the current generation of HollowTech II off-road cranksets (GRX, XT, SLX) and newer Dura-Ace R9200 and Ultegra R8100 cranksets.
Long: compatible with all other Shimano HollowTech II road cranksets including Dura Ace R9100, Ultegra R8000, and 105 R7000. Previous generations may have used the short version, such as earlier production Dura Ace 9000 series.
Installation
Screw the fixing bolt into the crank arm and tighten until all axial play between the crank arm and the bottom bracket is eliminated. Then, loosen the bolt by a quarter or half turn to ensure that no axial load is applied to the bottom bracket bearings, which would cause friction and premature wear of the bearings. Then, tighten the crank bolts to the recommended torque.
