Product Information
Full details
The Burgtec Shimano Crank Bolt is designed for mountain bikers and e-bike enthusiasts looking to replace their flimsy stock plastic pre-tensioning cap with a more durable, reliable solution. This CNC-machined aluminium bolt ensures precise tensioning for your Shimano Hollowtech II or e-bike crank system, offering a secure fit and a vibrant aesthetic upgrade. While it significantly improves durability over factory parts, users must exercise caution during installation, as the bolt is intended for pre-tensioning only and requires very low torque to avoid damage.

FAQs
Can I use a torque wrench to install this?
Yes, using a torque wrench is recommended to ensure you stay within the 0.7 to 1.5Nm range.
Is this compatible with Shimano road bike cranks?
This bolt is primarily designed for Shimano Hollowtech II MTB and e-bike crank systems; please check your specific crank spindle interface before purchase.
Does it come in other colours?
The product listed is the 'Purple Rain' variant, though Burgtec often produces this part in various anodised colours.
What happens if I exceed 1.5Nm of torque?
Exceeding the recommended torque may damage the bolt threads or the spindle interface. Always stay within the 0.7-1.5Nm range.
Do I need a special tool to install this?
No, it uses a standard 8mm hex key.
Troubleshooting
Bolt feels stiff while threading
Back the bolt out and clean the spindle threads. Ensure there is no cross-threading before trying again.
The bolt will not stay tight
Verify that your crank pinch bolts are properly torqued to the crank manufacturer's specification. The pre-tension bolt should only be tightened to 0.7-1.5Nm.

Setup, Compatibility & Care
To install the bolt, ensure the non-drive side crank is properly positioned on the spindle splines. Hand-thread the Burgtec bolt into the spindle until it makes contact. Using an 8mm hex wrench, tighten the bolt to the manufacturer's specified torque range of 0.7 to 1.5Nm. It is critical to stay within this limit; the bolt is designed for tensioning only, not for holding the crank arm against the high loads of pedaling (which is the job of the two pinch bolts). Clean the threads of the spindle before installation to prevent debris from causing resistance. Periodically check the bolt during routine service intervals to ensure it remains seated.
