Box One Cro-Mo kettingbladbouten 15st zwart

The tolerances are right on and the threads go together smoothly. Dab of assembly grease on the threads at install and you'll easily change out chainrings as needed. Buy a decent chainring bolt tool to make sure you tighten them well.

Sturdy bolt with plenty of length. Never have to worry about them backing out!

I thought I bought a good set of chainring bolts from a pretty reputable company (not gonna name names) and after installing them as per instructions using the inch pounds gage a couple of them broke after a couple of months of riding,they were alloy so I figured I'd try the Box chromoly versions for a replacement,I've installed them and haven't had any issues!

Works as they should, I wish there were a separate pack of the shorter ones for BMX single ring setup. I always end up with a lot of the longer bolts that I do not need.
