Are sram powerlinks weaker than other links of the chain ?(8 posts)

Are sram powerlinks weaker than other links of the chain ?PeterRider

I have a shimano ultegra 9spd chain with a sram powerlink. Do I have to expect that the link breaks before the chain ? How long do yours last ? Should I always carry a spare powerlink with me ?

I love being able to take the chain off, dropping it in the degreaser... and cleaning's done ! no more paper-toweling during 30 mins !

Never busted one and I use them for both road and MTB for several years now. If you think about it there should be no reason why they should be weaker - the cross sectional area with the minimal amount of metal remains unchanged between a power link and a standard link. The chain will stretch and get all sloppy long before the power link fails. When I do break a chain it isn't at the power link.

You using them with Shimano chains? Just curious, because I have used the power link with D/A chains for ~6,000 miles with no problems. There seems to be mixed opinions here and elsewhere about mixing the link with S chains, and I'm just curious if your experience is with Shimano/Power Link.

That's ~8,000 miles, spread out over three bikes.

Yes, I throw a Power Link on my Shimano 9 chains whenever I have a spare one, but mostly I've just been using SRAM chains for both road and MTB. I blow through a lot more MTB chains due to the harsh service life. The thing that gets me is that it's something like $5 to buy the Power Link seprately if you want to put it on a Shimano chain. Why not just use an SRAM chain an skip the extra cost? I find that the SRAM chain works as well as the Shimano chain and seems to last as long if not longer. There have been times when I've thought that perhaps the Shimano chain shifts a little better, but it's not an obvious enough difference in my mind.

I picked up a SRAM pc89r, I believe it is, a while back to experiment with. I began to use the Power Link with S chains to facilitate cleaning; pop it in a spent 2 liter bottle with odorless mineral spirits and give it an intense wash cycle, (shake like hell). Then hang dry and lube before installing with no mess on the bike/chainrings/der.pulleys/garage floor, etc.

Soon as I wear these out I'll fiddle with the SRAM chain. Thanks for your info.

My experience with the Sachs/SRAM Powerlink has been excellent. I have been using them since the introduction in 1998 and never had a problem. I find they last as long as the chain, and I change my chains about every 3000-4000 km.

I've been using the SRAM powerlink for the last 10,000k on my Campy 10 speed chain. Never had a problem.
