Full details
The Burgtec Shimano Crank Bolt is a precision-engineered pre-tension bolt designed for cyclists looking to customize their setup or replace a worn component on Shimano Hollowtech II cranks and E-bike motors. It is ideal for riders seeking to add a durable, anodized aesthetic to their drivetrain, though users must exercise caution with torque settings to avoid damage to the aluminum hardware.

FAQs
Does this bolt replace the pinch bolts?
No, this is a pre-tension bolt only and does not serve as a replacement for the two pinch bolts located on the side of the crank arm.
Can I use a standard wrench for installation?
You should use an 8mm hex wrench, preferably with a torque wrench attachment to ensure you stay within the 0.7 to 1.5Nm range.
Is this compatible with all Shimano E-bike motors?
It is compatible with standard Shimano Hollowtech II style E-bike crank interfaces.
What happens if I over-tighten the bolt?
Because it is made of aluminum, over-tightening can strip the hex fitting or the threads, making it very difficult to remove in the future.
Does it come with a washer?
The bolt is designed as a one-piece unit intended to seat directly against the crank arm.
Troubleshooting
Bolt is difficult to thread in
Ensure the threads are clean of debris and properly aligned; do not force the bolt as this can cross-thread the crank arm.
Bolt feels loose after a ride
Verify the pinch bolts on the left crank arm are tightened to the manufacturer's specification. The crank bolt only provides pre-tension; the pinch bolts secure the assembly.

Cons
- Requires very low torque; easy to over-tighten

Setup, Compatibility & Care
Installation is straightforward but requires attention to detail. Ensure your crank splines are clean and lightly greased before installing the bolt. Hand-tighten until the crank arm is fully seated.

Care Instructions:
