Shimano
Ultegra CN-6701 10-Speed Chain

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.

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

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.

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

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.

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.

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.

I purchased a used Soma Smoothie that was decked out with Ultegra components. After a few months into the rainy season, my drivetrain and shifting became dodgy, which turned to be due to a stuck link. Unfortunately, I couldn't un-stick the link, so I purchased this chain, which was identical to what I had. That made for a quickeasy replacement. Things are smooth, once again. )

Love the shimano chain great value for the price

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.

Shimano products have always worked out well for me

I use the chain on my road bikes & I average 300 miles per, the chains are very durable. Wish it was lighter.
