This was a great half link BMX chain, for the given price point. I generously won’t take off rating points for a defective chain breaker, since I luckily had some extra (better) ones on hand. I also didn’t use the included “master” pin. I typically run full link chains, but happened to get a frame with super short chain stays and dropouts. Because of this, I either had to have my rear wheel hub axle near the ends of the frame dropouts. It was either that, or I had to “slam” my full link chain with my sprocket and hub driver. I highly recommend to NOT slam a chain/wheel, as doing so absolutely gouges up the teeth of your sprocket and hub driver teeth… Also, running the chain so tight, will prematurely stretch the chain, and wear out the rear wheel hub driver bearings.

The first time out riding after installing this chain(correctly) it snapped in the middle of a power pedal while crossing the road causing me to fall headfirst into the asphalt in front of mid day traffic causing my headphone to explode in my ear and embed itself into my head.

Good product, did what I needed it to do, don't push the chain all the way out the other side like I did.

Looks great once installed, but it is a pain to put on. The supplied pin broke before I was able to press it all the way in. Was able to make it work after some time messing with it.

Don't let the low price compared to something like the Shadow brand halfink chains fool you, this is a solid chain made by a brand that has been around much longer than Shadow conspiracy and has a great reputation! This chain is made by and stamped 'KMC' and is very high quality! The included chain tool isn't the best but it does get the job done. Save some coin and purchase this chain instead of Shadow.
