Shimano Ultegra CN-6701 Chain

Goodbye missed shifts.

Run the Shimano Ultegra CN-6701 Chain in between the twister and the twistee for reliable, fast-shifting performance thanks to the innovative Hyper-Glide system. Shift pins and ramps on Shimano chainrings and cassettes mesh perfectly with the Ultegra chain, ensuring you won't miss a shift when riding aggressively.

so far so good

  • Familiarity: I've used it several times

Chain seems just as good as sram but I do like using a quick link over having to push a pin to connect the chain.

Unanswered Question

Does this chain fit the Ultegra 6800?


  • Familiarity: I've put it through the wringer

Does what it is suppose to. Can't complain

Good all-around chain with limitations

    The 6701 is a reasonably-priced chain that works well on Shimano 10 speed configurations, but there are some drawbacks that come with the savings. It shifts reasonably well with both Di2 and mechanical configurations, but I think it's more abrupt than the Wipperman 10S1 or the DA chain, espcially if you are a frequent shifter or tend to shift under torque. The Shimano attachment link is a pain, do yourself a favor and buy a Connex link to use on this chain and other Shimano and Wipperman chains too.

    Also I have had to replace 2 of these chains due to cracking a plate during sprints. It presents itself with a "TING!" sound, and while it will almost certainly make it back home, you'll want to lay off the sprints until you get home and replace it. The picture attached is a piece of a DA-7900 chain broken the same way, as an example of what to look for.

    I say that I have used it several times because I was given 2 of these free, and broke each of them within 1,000 miles.

    Good all-around chain with limitations

    Question on the broken chains: were these installed with links facing "forward" per the Shimano tech doc? I realize this is like the question "did you plug it in?"; no offense meant truly. Just trying to understand if these things are breaking without any error influencing it. I do know that the DA 7801 does NOT have direction-specific links whereas the 7901 and the Ultegra 6701 DO. Post it up if you happen to see this.

    No offense taken! The chain was installed properly, logo side out. Drives me nuts when they're wrong. This one was installed with the stock Shimano pin, and not a Connex link, though the crack had nothing to do with the pin. The Connex link has worked fine on over 15,000 miles of use with DA chains.

    Not for triple cranks!

    • Familiarity: I returned this product before using it

    This chain is not recommended for those running a triple FC. Shimano recommends the older Ultegra 6600 chain for triples. LBS folks also suggested an XT/XTR chain as an alternate.

    Is this chain really for a ten speed bike?...

    Is this chain really for a ten speed bike? Two sprocket front, five sprocket freewheel?

    Best Answer

    This chain is made for 20-speed drive train - which is two rings in front, and 10 in the back. I wouldn't get this for that set-up.
