Review on 10 Pack of 8mm Hex Crank Arm Fixing Bolts - Premium Bicycle Crank Screws for Square Hole Crankset Bottom Bracket by Justin Hines

Revainrating 3 out of 5

Rubber grommets too small to seal crank bore

The screws themselves are fine. They thread easily and come with a drop of threadlocker. However, the rubber gasket is noticeably smaller than average and cannot seal the crankholes on a kid-size (with 140mm arms) square-bar crankset.

Pros
  • Kit Contents: A pack of 10 fits in a large plastic bag. 0.31'*0.71'.
Cons
  • -
