There are two things that I like about these chainring bolts. First, they are steel rather than aluminum, so you can really torque them tight. Second, they go off and on with standard metric Allen wrenches, and you do not need a special chainring bolt wrench.

The fact that so many chainring bolts out there require the useless flat bolt tool that is nearly impossible to hold in place under torque is a scathing indictment of the skills of many a bike engineer. The Truvativ design makes it starkly clear how utterly incompetent the designers of these absurd alternatives are. If you have these other bolts on your bike, do yourself a favor and replace them with the Truvativ bolts (that is, once you manage to get them loose, since the slots are almost certainly partly stripped from the installation process). You will be dumbfounded that any other design ever existed.

It holds sprocket. I had to get washers

Excellent service and product.

These are well engineered replacements. Arrived as expected. Thanks
