    • Nice half link chain for the price
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. ... show more

    • KMC.... Need I say more?
Review Image by mike mike
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. ... show more

    • Chain breaker won't even install it.
Review Image by Lee J Creighton Lee J Creighton
Chain might be good, but I can't install it because the chain breaker stripped out immediately. Had to spend money on a different one.

    • Looks great, but.......
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.

    • Thing looks just as good as shadow conspiracy!

KMC is just as good, looks great and came lubed and ready to go. Be cautious with the chain breaker. You just have to use it right and it will work.

    • Great chain…. not the best breaker.
The chain is high quality and was cheaper than my LBS. Wound up going and purchasing a Kink chain breaker from the LBS and now very pleased. The breaker included with thechain just slid off the head of every pin I tried it on. I have an even cheaper breaker from a Spin Doctor kit that works better but wanted something with a more comfortable handle and longer pin capacity so went with the Kink. ... show more
