Odyssey Bluebird BMX Chain - 1/2x1/8x112L - Gold 9t This bottom bracket is designedFor the Bluebird chain, Odyssey took the proven and reliable KMC 510 HX chain and added a permanently attached, factory installed half link to one end. When the chain is trimmed to size you can easily decide whether or not to use the half link. The original factory assembled pin joints are radically stronger than workshop assembled half links.
