Metal is too soft.
Be very careful with installing these. The metal used is rather soft and can easily round out causing all sorts of problems with trying to uninstall, but nothing like a handy pair of vice grips cannot handle.
Other than that little thing, it works great.
Although I would recommend adding a spacer/lock washer because it bottoms out quickly. The lock washer is to make use the bolt doesn't come loose. Adding locktite might cause problems when taking it out since the metal alloy is soft.
Used this on a DA 7400 crank arm with dimension 42T chainring.Pros:
Works as intended.Cons:
Metal too soft. Be extra careful with tightening and loosening. Would Buy Again:
