I had mistakenly ordered a longer size than I needed, but they worked anyway and they really look great. They are a huge improvement over my old ones. I had thought about buying black aluminum bolts, but I am glad that I decided to stick with the steel for the strength.

I wish I had back the couple of hours and spoiled rides from trying aluminum double chainring bolts. They just didn't last 10 miles of pavement riding. Coming back from a spoiled ride I swapped these in and could really feel confident that I was able to get them tight without stripping and they were well crafted.

Needed when upgrading from a 3x7 to a 3x9 as I had to decrease the gap between the small and middle chain ring. They even came with the correct spacers. Quality seems okay but they definitely held tight when installed.

The description of these items are hard to understand and inadequate, but the parts themselves are good if they fit your application. The inner chainring set includes 5 of each:3mm wide spacers10mm long bolts (measuring the threaded portion only)This was just what I needed ... but the spacers for my setup required 4mm and these are only 3mm.

These worked well for me. One of the other reviewers attached a pic of the package in their review, which is accurate to what I received: Five 10.5mm length bolts and five spacers, which I believe are about 3mm. One of the Q&A threads mentioned that the bolts are 12.3mm, but that is not what I received. I received 10.5mm length.The bolts and spacers are well made and the metal appears to be good quality. However, the spacers are much bigger internal diameter than the actual bolts, which can be a good thing, except that the external diameter is consequently bigger, which can be bad when fitting the spacers into the crank spider. But, they ended up working for me regardless. Just something to be aware of.Luckily, Jens*n has the 12.3mm bolts for only $1.99, so I was able to test with both lengths. In the end, I used these Origin8 bolts with the spacers.

Works great! I somehow lost a bolt during a ride and purchased these to replace it with. Works perfect!

Did not include the nuts as described in the listing. Not useable as is. Should have read the other reviews first!

The half that's the allen screw is great. It can be used to attach road bike inner ring (grandma gear) and other uses. However, the part that's a nut doesn't have any strength. Buy these for the screw part (allen wrench fits) and discard the other part (outer jacket--no allen fitting).For use with double-rings, do keep the steel nuts from your oem set.Compared to FSA and Truvativ where both parts fit allen or torx and both are strong--well, this product is about half as useful as those.
