Lighter, cleaner, quieter, longer lasting, smoother, more responsive... This belt and timing ring set shaves more tandem weight than a carbon fork upgrade.
Already gaining popularity in the single speed world, this Gates belt drive system is the perfect drivetrain upgrade for tandems!
We can tell you that the Carbon Drive lasts many times longer than a traditional chain and chainrings and never needs lube, so it's cleaner. Your stoker will never have a grease chain tattoo on their left calf again! Sorry, we can't help you with the right leg just yet.
Our belt and ring system weighs in at 295 grams on our scale. This setup saves about 225-280 grams (8-10 ounces!) compared to a traditional timing chain and chainrings.
Made by Gates exclusively for Co-Motion Cycles tandems. This is the same system that is now standard equipment on new Co-Motion Supremo, Robusta, and Macchiato race tandems.
One length only - which means that this system will only work on all stock sized Co-Motion tandems (28.5 inches or 724mm from BB to BB, center to center). Custom Co-Motion tandems with lengthened (or shortened) stock compartment will not work. Once installed and tensioned the distance between BB centers is 28.5".
Includes the amazingly light Co-Motion Gates Carbon Drive timing belt and a set of the Gates Carbon Drive 130 BCD timing rings.
NOTE: These are only recommended for use with the new FSA adjustable chain-line cranks. If you're running the newest FSA tandem cranks these will bolt right on in place of your current timing rings. Ask us if you have questions regarding compatibility.
Set up takes a bit more time as chainline is now extra important, but once aligned and tensioned you'll seldom need to touch it again.
