This is the Odyssey Bluebird chain: strong, simple chain with the Half Link built in for exact chain tension adjustment. All wrapped up in some cool retro packaging - love it.

The following is From Odyssey BMX

• The Bluebird Chain uses a standard KMC 510-HX link and plate configuration and includes a KMC Pintle half-link that’s pre-installed at the factory. The idea of the pre-installed half link is simple. If you need the half link, than shorten the chain at the other end. If you don’t, than shorten at the half link end. The Bluebird is available now in black, gold and silver.

• The Bluebird is the first production chain that we’ve ever offered for sale, and it stands as the precursor to an all new design that we’ve been working on in various forms since before our “official” collaboration with G-Sport began over six years ago. We’ve developed and abandoned numerous concepts. Some were patented, and something similar to one of them is now being offered by another brand. We are currently in the final ride-testing phases of our latest design, and it’s at the pre-production level, which means that the tooling for full production is nearing completion.

• As we continue to test and develop this new design, the rest of us are happily riding the Bluebird, which offers the reliability of the proven 510-HX with the precision of a factory installed half-link. We hope you’ll enjoy it as much as we do.
