Break and re-join the chain with just a 3mm hex key. Half link plates are less narrowed at the bends to increase stiffness and minimise stretch. By eliminating the use of a chain breaker to re-join the chain we can ensure factory tightness on all the pins.

1. Oversize Pins: Traditional chain pins are 3mm in diameter. The Key Chain’s are 5mm, and they are available with a hollow or solid pin assembly. These oversized pins are 4-times stronger than traditional pins, and the chances of bending one, whether the pin is hollow or solid, are essentially zero. The 5mm riveted pins provide added strength, but they also provide a bigger contact surface with the chain’s plates, which makes them harder to push out or bend. The hollow pin assembly, by design, allows for a stronger rivet connection to form during manufacturing, resulting in a stronger chain overall.
2. Thicker, Lower Profile Side Plates: Each plate has a low profile and an extra narrow waist that makes it harder to catch the plates at unwanted times. At 1.4mm, the plates are substantially thicker than the plates of any other chain, and they’re also more than 50% harder to bend than the thickest existing 1.2mm chain plates too.
3. Unique Master and Half Links with Threaded Pins: Users can break and re-join the chain with just a 3mm hex key. The chain’s half link plates are taller at the bends to both increase stiffness and minimize stretch. Since the use of a chain breaker to re-join the chain has been eliminated, the pins can retain their original level of tightness from the factory. Also, carrying a spare master link and 3mm allen key in most cases is enough to repair the Key Chain when riding, so lugging around a chain tool is usually unnecessary.
4. Low Overall Weight: By using material as efficiently as possible we have strengthened every component of the chain and kept the weight in the same range as our Bluebird chain.
5. Low Stretch: Stretching of the chain is minimized by using a standard alternating plate pattern and limiting the chain to a single, beefed up half link. This configuration maximizes the lifespan of the sprocket and driver.

I have had the pleasure of running this chain for a couple of years now. I could tell from the very first sample that Odyssey was on to something because even though I was purposefully punishing my chain, it refused to break. Fast forward to present day and the Key Chain has seen many refinements and I believe a new bar has been set for bmx chains.

I’ve been riding the Key Chain for over 4 months now and it hasn’t broke once. I can’t say any other chain has held up like this one does.

I’ve been a fan of this chain ever since I put it on. It’s easy to deal with and looks rad.

The Odyssey Key Chain is the most reliable feeling chain I’ve ever ridden. With its thick plates and durable pins, I don’t need to run a guard sprocket because after testing it I know it’s gonna hold and I won’t have to check for busted links after bashing and grinding it!
