Review on πŸ”© BlueSunshine 15mm Crank Bolts for Head by John Clark

Revainrating 1 out of 5

Easy to cut when installing!

They are broken. I had a pair of scissors complete and others started cutting as I installed them. See image. This damage occurred at a torque well below Shimano's recommended torque for the crank bolts on the bottom brackets. I see another user shearing off these bolts while riding, so I'm not the only one. Proper installation technique will shear or loosen these screws significantly. They are dangerous.

Pros
  • In manufacturer's retail packaging.
Cons
  • Expensive
