Powerlink and CN-7701

[frenk]

I couldn't find an answer to this question, and before taking risks I just want to be sure.

Is it safe to use a SRAM Powerlink (9spd gold) with a Dura Ace CN-7701 chain?
It seems to fit well, but I can open it really easily. So will it stay closed, even on bumps?

If no, is there another solution, less costly than replacing the pin each time I want to take the chain off? (and I really want to take it off!)

thanks for any advice!

Neither Shimano nor SRAM recommend this. However, I do know
people who do it with no problems.

You could use an SRAM chain, which comes with a free
powerlink. SRAM says their 9sp chains are compatible with
9sp Shimano drivetrains.

I've used the SRAM gold powerlink on all my Shimano chain
equipped bikes
(5), including our tandem, for several years now. Never had
any problems with any of the chains/powerlinks.

Several people among my riding buddies are using Shimano 10
sp chain in their Shimano and Campy 10 drive trains. The
Sram Powerlink II works better than the Connex 10 link and
the IRD link. With the later 2 links, they have problem with
the 11t cog or hear clicks from the removable link. They
prefer the DA 10 chain for economy.

If you search this message group. you'll find many messages
on how to open stubborn Powerlinks.

The powerlink seemed a bit too easy to open on the DA 7701 chain: just push the two faces together and voilà. I could do it simply shaking the chain!
I'm sure it would have happened 50km away from home.
Here is what I did: I modified the faces to make them *slightly* point to the outside, so that in order to open the link a bigger pressure is needed.
I can now hear a clear "click" closing the link, and I can open it with a little more force.
Maybe this wasn't really needed, but I prefer a little more pain to open the link when I'm at home than a broken chain somewhere alone in a mountain!

Thanks for the replies!

If installed with the shalllow portion toward the cogs, no
problem with an 11t cog, for thr Connex.

My Connex works fine with my 11t.

There's a shallow portion?

And, face it toward the cogs when on the top run or
bottom run?
