Odyssey Keychain
Never satisfied with the status quo, the OTX Design department always has some sort of wild, futuristic product in the wings and for 2013, the Keychain is one of these products. While the typical 510 design still does the trick just fine, the Keychain improves on the design with hollow pins that have a larger diameter (more strength) and a 3mm threaded master link and 3mm half link that eliminate the need for a chain breaker. Pretty cool–another good idea from the Odyssey camp.
