Why We Like The Shimano XTR/Dura-Ace CN-HG901 11-Speed Chain
The XTR/Dura-Ace CN-HG901 Chain keeps our bikes shifting with precision, and pairs brilliantly with Shimano's top-notch XTR and Dura-Ace 11-speed drivetrains. This model features a revised plate profile that's compatible with E-bikes and single-speed applications. The chain's slight asymmetry pairs perfectly with Shimano's 9000 series drivetrains for silky-smooth gear shifts and greater power transfer, and the low-friction SIL-TEC treatment glides across your cassette's cogs with minimal friction. Ultimately, this allows you to focus on riding without worrying about your chain keeping up with rapid shifting and high-cadence efforts.

Excellent chain
- Familiarity:
- I've used it once or twice and have initial impressions
This is the first Dura Ace chain purchase and am curious to see it's longevity, but so far it has met expectations. This was matched with my Dura Ace 11sp cassette which has been great as well.

This made in Japan chain is astounding good. I’ve been using DA chains for 35 years and they’ve never let me down. I changed out my most recent at almost 4K miles just bc I thought I should (the chain wear indicator showed only the barest amount of stretch) and there was no problem with chain skipping on the old cassette (I go two chains to one cassette). Of course saying these are great chains almost seems pointless—everyone should know this by now. If you hear something negative about these chains my guess is that it was about a fake—which are prevalent on e-bay (don’t know if the de minimus loophole closure will affect this). It’s not worth buying a fake; buy from a reputable seller like competitive.

This chain is an excellent match for the Ultegra drivetrain.

New chain for your bike is like getting a new drive train for your car. Every rotation is smooth and glides like butter. I've ridden with Shimano Dura-Ace for decades. It's a reliable product and I trust purchasing components from reputable merchants like Competitive Cyclist.

They're the best

You don't really think much about your chain, but there is nothing like a chain that works so well you forget about it. Shimano chains just sorta work. I know they test .5w faster on some marginal gains gizmo that has a margin of error greater than they are measuring, but I'm more looking for something that just works. Shimano chains, on their drivetrain parts, are incredible. Under load, spinning fast, whatever, they just work and I'm good with it. I'm a chain waxer as well, and they do seem to last many thousands of miles. My one bike that doesn't get bad weather has gone closer to 5000 miles before I decided to change it. It didn't seem possible and I changed it out of paranoia. More expensive, but there's a reason they cost more, it's not just fluff.

Get them new. Clean them thoroughly and use a wax based lube. Go Fast.
