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.

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 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. )

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.

Love the shimano chain great value for the price

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.

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.

Great chain. Great price.

Remove chain completely,no degreasers throughly clean every 2-3 rides (100-150 mi.) check and wipe down every ride with very light coat lube for cleaning purposes fully lube 1 drop per link when chain talks to me.

Quiet and easy to install.

good product - performs as expected

Good chain made to last, just keep it clean and it will.

Lasts much longer than the Dura-Ace chain, for only a very small increase in weight.

Good replacement for the original chain, shifts easy and quite. Easy installation after matching up the number of links. Just oil and it's good to go.

nothing to dislike.

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.
