Shimano
Ultegra CN-6701 10-Speed Chain

Of fools. Pandemic allowed me to ride more miles in 2020 that normal and led to the rookie mistake of waiting too long to replace the chain which often time leads to replacing the cassette too. As was the case this time. Word of advice for the DIY'er, make sure you have a quality chain tool and use the right pin as 9sp, 10sp, and 11sp are all different. If using a master link, you'll find it much easier to connect with Master Link pliers like Park MLP-1.2.

I recently purchased this chain as a replacement for a KMC chain I had previously. My bike had a mix of Shimano 105, KMC, and FSA components, but I've made a couple upgrades to Ultegra as I wore parts out. I found this chain to be easy to install and it's running smoothly on my bike now. I've noticed that my efficiency has increased slightly since installation, which has translated to several unexpected PRs on Strava segments. I am very happy with the high standard Shimano has set with their components, and Ultegra is a great balance of performance and price.

A new chain can make your bike run like a deer. I love my Cannondale caad10 Ultegra, but even more when my favorite mechanic Todd puts on a new chain and tightens up the derailleur. Ride safe, but wear a bracelet with your medical contact.

Replaced my original chain after 3600 miles (still had life left) on trek road bike. The shimano is lighter and shifts smoother than the original even when new. I get good miles out of my chains as I clean them every 150-200 miles. I remove soak them in simple green, scrub with paint brush, rinse and blow dry with hair dryer, reinstall with master link then use Motorex road strong motor cycle lube. I know your thinking this guy is text book OCD my wife keeps telling me that, never the less my LBS tells me what ever I'm doing its working.

Cleans easy and last long.

Good reliable chain that is quiet and shifts well. I train a great deal for all types of road races and go through several chains each year. Caught these on sale and stocked up for the year. The order was shipped quickly and arrived within a few days. I have always had good service from Western Bikeworks.

Great chain. Great price.

I have an all Ultegra 10 speed drive train, except for FSA cranks. I ran Ultegra chains for a couple of years, but then came across sale on Dura Ace 10 speed chains and decided to try it. No perceptible difference in performance or longevity, but noticeably quieter that Ultegra. Now I can't seem to find Dura Ace 10 speed chains anywhere. Perhaps Shimano has quit making them. Anyway, the Ultegra chain is a great chain and if you find it on sale get a couple.

Hi I am new rider and I don't know very much about the 10 speed chains. Does it fits any size? I had a 10 speed cassette Shimano.

Well made, lasts longer than other brands, use on tandems and single bikes

Chain is good came as original equipment with my BMC.

I like using A pin in stead of quick release

This chain was easy to install and works well with my new cassette.

Nice quality 10 speed chain. Works well on Shimano drive

Great quality, good durability for a good price. Been using these chains for years!

I typically get about 3500 miles of usage from this chain before replacement is necessary due to wear.

standard chain, good value, use tool for pin

need chain tool to shorten and put pin. Keep lettering on chain outside (to the right) per picture supplied with chain. easy to install

7,000 miles a year,replace at 0.75 wear indicator

use on a road bike. Plenty long to fit big gears. Easy to install, just be sure chain writing is facing out as it is directional which improves shifting. I install a removable master link for easy cleaning. It would be nice if Shimano included one but the pin also works fine. Google the chain for specific installation instructions. In case the chain breaks, a spare master link will get you home.
