9 speed duraace question

Hello,

Hello!

Can a standard chain tool be used to remove + fit this chain?

I guess a specific 9-speed chain tool should be better, but not really sure.

Also, how is its durability compared to Ultegra?

Assuming you are talking about the chain, there should not be any big
difference in durability, but I see Ultegra equipped bikes with DA
chains all the time. BTW... does an Ultegra chain exist?

Sure, but i would recommend a SRAM Powerlink or simular to fit the
chain.

General group duability is OK with the exception of the STI levers which have
been to known to fail early-ish, requiring warranty or over time, requiring
replacement. Not servicable.

I have both the Shimano 7/8sp and 9sp HG chain tools, and I recommend using the
9sp chain tool to install a Shimano 9sp chain. The side plates on the 9sp chain
are slightly narrower than on the older chains, and it's a tight fit when using
the older chain tool. You don't want to bend or distort the links at all when
pressing in the pin.
There is no functional difference between the Dura Ace 7701 and Ultegra HG93
9sp chains. Both the inner plates and outer plates on the DA chain are nickel
plated, where only the outer plates on the Ultegra chain are nickel plated.
Durability of chains has more to do with riding conditions than the type of
metal plating on the links. On the other hand, the DA chain only costs about $3
more, so it's no big deal either way.

Hi, I believe the only difference between the Dura-Ace CN-7701 and the
Ultegra CN-HG93 is that the Roller Link Plate is gray on the Ultegra.
The DA is all zinc-alloy plated. They weigh the same at 304g.

I have been buying the DA chains from Performance, on sale for $19.98
and then take off another 20% if you happen to be buying over $50
total and use an online coupon. Finally finish that off with 10% on a
future purchase, as a member of Team Performance. So a DA chain for
appr $14.40.

I'm easy on equipment, so I'm not a good gauge of durability, although
I have not had one break, and at that price, I can change them when
they measure wear.

I would second the recommendation for the SRAM Powerlink. It makes chain
removal very easy, and there's no hassle during re-installation.
Particularly excellent for work while on the road. Use 'em on all our bikes.

I have been getting about 4000 miles out of my Dura-ace chains. I keep them
pretty clean. I toss them, when my chain-checker shows them to be stretched
(although I'm not really sure if the chain-checker is accurate, because the
system is still shifting just fine). I am now on the third chain on the same
cassette, too, so you don't need to chain your cassette. BTW, the shop that I
work at recommends changing the 10-speed DA chain at 1500 miles and discourages
the consumer from changing it themselves (supposedly it is easy to screw up).
Sorry, I got a bit off-topic.

Don't they have a chain length checker like a Park CC-3 or Rohloff? They should
and then measure before recommending replacement of any chain.

The gig with DA chains is that the pin needs to go into the segment of the
chain with the inside part of the link 'pulling' or going forward.

OR just sue a mavic/Wipperman 10s chain..

Peter, this is the first time I have seen any info, on the direction
of the chain, related to the pin.

What are the potenial problems if assembled the other way?

Maybe I have missed it, although I don't believe Shimano, gives any
info on this with the new chain.

I appreciate the info, thank you!

I use the same chain tool for my DA9 as I used on 6-7 and 8 speed chains. Its a Ciclo Rivoli brand name tool.

I used to use the "special pin" but now use a Forster Quick Link. I never had any problems with chains.

As far as the quality of DA chains, they have a different pin than HG93. There is some kind of super-hard plating on the pins. The older DA9 7700 chains had a slightly different peening which cracked this plating near the ends. The 7701`chains have a central peening, preventing this problem and making for a more corrosion resistant chain.

This different pin you speak of, do you know this to be a fact or is
it something you have heard?
I can't find anything mentioned about different pins on the Shimano
Technical website.

CN-HG93

I believe they use the same "special pin".

I'll second the lever problem having just experienced that last week.
🙂 I run an SRAM powerlink on them. The DA chain is plated on both
the inner and outer links which I think makes for a nicer looking chain.
A little bit of Rock-n-Lube and it will go a long way.

May break, has on two DA 10s chains we have seen. I rec. a mavic/Wipperman 10s
chain or at least a Wipperman snaplink with the DA 10s chain.

Info is a teeny little note and pic with the chain

Ok, DA 10s, what about the DA 9s? Ioverlooked the part about you
talking about 10 speed chains. I'm using the CN-7701, are the concerns
the same?
Thanks again.

No, just the 7800 chain which has so much thinner side plates.
