Single-speed chain with a half-link for easy adjustment
The Odyssey Bluebird Chain is a single-speed chain born with a half-link. The half-link makes length-adjustment easy so you'll get a nice and tight chain that's totally dialed in all the time.
Whether to use the half-link or not is up to you and your setup. However, it's indeed nice knowing there is an opportunity to make a perfect fit if needed!
