### ⭐⭐⭐⭐⭐ Good product but couldn't use
*by P***R on May 16, 2016*

Appeared to be a well-made quality product but I could not use because I did not read the description correctly. These are for a single chainring I need a double. The seller was very good about taking him back and refunding.

### ⭐⭐⭐⭐ Great looking product, watch the torque...
*by S***T on May 1, 2015*

I couldn't find any company published torque specs for this product so I tried two different one based upon general guidelines I found online. 50 ft-lbs worked fine, 75 ft-lbs broke the bolt, but I had a spare. They look great, I just hope they stay put and function properly at 50 ft-lbs.
