sram links with shimano chain question

I just recently bought a few spare power links from sram and I was told by some people that they could be used with a shimano chain, but when I read the back of the package it said that use of the power link with any other chain except for the few stated on the package "WILL RESULT IN FAILURE OF CHAIN". Can anyone tell me if this is true or not...even the spair sram 971 chain i bought is supposedly not compatible with the spare power links...can anyone shed some light on this for a newbie...thank you in advance

I have been using my Shimano chain with a SRAM powerlink...haven't had any issues until today. Was doing a very fast descent on a really rough trail...came to a short steep climb...went to pedal and nothing. Thought I dropped the chain but I looked down to see that I didn't have a chain. Had to walk back a long way to find the chain...got the chain but the powerlink was nowhere to be found.

It's not really true. SRAM 9 speed power links work just fine with Shimano 9's. Not so much with the SRAM to Shimano 8 speeds however due to the Shimano's being just a touch wider.

Raiyn is correct, it might not be optimal, but it works just fine. And I do not know what you mean by the PC-971 not working with Power Links because that chain comes with a Power Link.

Another option you can look into is the Wipperman Connex - I don't believe that they claim that it is only compatible with certain chains. It also seems to be a little harder to get in so if you have a situation like never in which it pops off, chances are the Connex will stay with the chain a little better than the Power Link. Either way always carry a spare, I do even for road biking.

I think it might be just a little white lie to make some more money.

Peoples! When carrying an extra link make sure you have both pieces. Glad i didn't need mine as i was carrying around only one side for atleast 3 weeks.

I'm glad you brought this up Raiyn, it gives me a chance to tell my story of helping a guy last year. Riding a trail, I came across a rider needing help. He'd broken his chain. I had a shimano replacement pin and an Sram gold link in my seat bag. (both 9 speed) I started to help him and used my chain tool to take the bad link out, and that's when I noticed he had an 8 speed drive with a shimano chain. Well at this point there was nothing we could do but try something. I tried the Sram gold link and naturally it was a little tight to try and lock in. I noticed he had good sized arms on him. I showed him how the link worked,and what we needed it to do,and told him if he didn't get it locked in he'd be walking back to his car! To my amazement, he got the link to lock in. I turned the bike upside down and rotated the cranks to see how bad the tight fitting link was going to stick, and again to our amazement it spun free and shifted well. I instructed him it may not perform well and that he should head to his car, and to the nearest bike shop for a replacement chain. He ended up finishing his ride before he left for the day. I guess my whole point is that the quick connectors and replacement pins are a great thing to have on hand. To the OP, I use Sram links on shimano chains myself, no problems in two seasons.

I'm running a Shimano HG whatnot with a Sram gold power link no problem.

A friend was recently running a 8 speed Shimano chain with an Sram power link. It was a ***** to connect and disconnect but other then that he had no problems.

Scary, huh? One question to ask yourself:

"Do you feel lucky? Do ya?"



Seriously it's no problem. I do it all the time. Next time you replace the chain buy a sram and save the extra $4 on the link.

To your amazement? That shouldn't have worked at all. Perhaps he was actually using a Shimano 9 speed chain on his 8 speed rig? The Shimano 8 speed chain is typically about 7.1- 7.3mm wide opposed to the 6.9mm width of a SRAM 9. Putting a SRAM 8 speed link on a Shimano 8 is damn near impossible but a 9?!?

Well I suppose it could have had a 9 speed chain on an 8 speed drive, as I didn't have a way to measure it. I do know that I couldn't get it even close to snapping in, and I take off and install mine on my shimano chains all the time.

I just don't know man, like I said that shouldn't have worked at all. Dude must have had bench vises for hands

Raiyn, your 6.9 and 7.1 had me questioning myself last night but then it dawned on me! these nubers are width of the chains not the width of the inner plates that the quick connectors are connecting to! LOL I started to think I dreamt the incident.

The point still stands since the inner plates are wider as well. Most 9 or 10 speed chains have an inner plate width of 2.15-2.28mm when new while most 5, 6, 7 or 8 speed chains have an inner plate width of 2.35-2.45mm. A 9 speed link shouldn't work on an 8 speed at all.

Raiyn is correct.. I've tried it.

A little off topic.. I personally prefer the Wipperman Connex. It is easier to work with. I was trying to clean my Sram chain and couldn't get the darn gold link off so I gave up.. but then, it is easier to spot.

Well...... I don't know what to say, This chain was old and worn to the point of breaking, so manufacture'es specs on new chains don't mean that much. All the "shouldn't of, wouldn't of, couldn't of's" doesn't change what happened. I'm not saying it will work all the time but the point still stands. These are handy Items to carry with you in case of emergencies.

My lbs mechanic friend says that he's found that the gold link will only last half as long on a Shimano chain than on a SRAM chain. How he could tell I don't know.

I carry several in my hydration pack. I can imagine letting the chain slip and propelling one of the halves into the leaves some where. Happens in the shop (minus the leaves).
