2.67/5 (9 Reviews)
MSRP : $70.00


Product Description

The new 10-speed Dura-Ace chain is lighter by an astonishing 24g, yet maintains the same durability as the 9-speed predecessor. The chain also adds a new fluid-smooth feel to the performance of the overall system.

Strengths:    The DA chain is of course, quite light. It also shifts beautifully with my 105 drivetrain. When it's all clean, it's pretty and shiny.

Weaknesses:    Well, it doesn't work. I'm a bit of a clydesdale, and the chain really complained on any climbs, and on what turned out to be the last climb of the day, the chain just broke. It looks like I lost a side plate. After numerous failures/repairs, I had to ditch it. I might make a chain whip out of it. It'll be the prettiest chain whip on the block!

Bottom Line:   
I was very disappointed by the quality of this chain. It hasn't lasted me even one ride, and after numerous repairs, it still doesn't want to work.

Strengths:    Durability.....ha,ha,ha That is a joke

Weaknesses:    Craftsmanship

Bottom Line:   
This chain sucks *ss. I used chain 4 times. Once on my trainer and it broke one side of a link off so I fixed it. The next 2 rides were fine. Then a pin fell out and took my derailer with it and bent my hanger and stripped the hole. The hanger is alum. and LBS said that if they bend it back it will fatigue and break. So now my frame is toast. Thanks Shimano for make a complete piece of crap and killing my frame.

Strengths:    Perfect shifting, looks good, very quiet and smooth feel. ,

Weaknesses:    I've run through four of these, and once, had a link start to come undone. I soft pedaled back to my car and it held together. I did have about 2,500 miles on this chain that went bad. Since, I change the thing out at about 2,000 miles, and it's been fabulous.

Bottom Line:   
I keep my D/A derailleurs well adjusted, and the thing shifts like a dream. I dunno, but I think that some of the complaints others might have are from not keeping the chain clean and lubed, and their drivetrain well tuned. I've wanted to try the Wipperman, but can't bring myself to pop 35 bucks (on sale) on one.

Strengths:    It comes with a Dura ace Build kit

Weaknesses:    Replacment pins. Noisy.

Bottom Line:   
Chain came with Dura-Ace Group. I bought a new frame this year and transfered the group to a new bike with a new Dura Ace Cassette and SRAM PC-99 chain. I never realized how poorly the Dura Ace Chain shifted. It is also very noisy. I had to put up with Shimano replacement pins when a SRAM powerlink works simply and does not require special tools. I can only thank the guys at my LBS for recommending the SRAM.

Strengths:    Nice when new

Weaknesses:    Not so nice when worn.
Incompatible with worn cassettes.


Bottom Line:   
Although designed to work well with the entire DA gruppo, this chain is lacking in overall performance. This chain only likes perfectly new cassettes and is unforgiving if either is worn. As with the rest of the DA gruppo, this chain should be considered a high performance, high maintenance.

Similar Products Used:   SRAM 99. Easier to clean. Perfect replacement for DA, shifts better under all conditions, regardless of cassette wear.
