First generation (silver) Rival, but first built up this summer and only about 1000 miles on it. Middle of a ride, shifting fine, dropped to the small ring to ride up a hill, get to the top, try to go back to the big and it clicks but no shift. The cable still has what seems to be full tension, but there is less resistance to the lever. It still clicks, but no trim or shift or perceivable pull on the cable.

I have only peeled the hood back and tried to look around but I couldn't see much and I don't know much about the double taps. Any suggestions on where to start?

Thanks in advance, Steven.

Alright, hasn't anyone else had one of these go bad? Has anyone ever had a shop rebuild one?

I'm guessing the shifters are being exposed to cold weather for the first time. Saw this last winter, with practically new SRAM shifters. A few shots of WD-40 into the shifters' innards loosened things up and the shifters started working again.

So you do work in a shop?

I was under the impression that thoser shifters aren't rebuildable.

well biked

Yes.

I don't think they're rebuildable. A guy came in on an early winter day, frustrated with his practially new SRAM shifters that exhibited signs of the dreaded dead shifter syndrome, and I used a bit of WD-40 to bring them back to life. I've seen him on the road occasionally since then, he says the shifters are doing fine-

Have you guys ever had any front 53/39 shifting problems with full force/rival? Assume new drivetrain.

well biked

No, although we don't see a LOT of bikes with full SRAM drivetrains. I've worked on a few, and one of my co-workers has two bikes with all-SRAM stuff, one with Force, one with Rival, both with 53/39. He loves it, says it shifts great.

Thanks for the advice on the WD-40. This did happen on the coldest ride that the shifters have been on, although it was above freezing I believe. But I'll give it a go tonight.

For what it is worth, my set up is full Rival with a 53/39 crankset but as I said the older silver group.

Sounds like you've got the answer, the grease they put inside shifters can gum up the works (especially in the cold) usually a shot of lube will get them working again.

canam73

Hey, one more quick question: Is there anything better than WD-40 for this? I do have some, along with some Park Lube, Slippery Spit, Kroil and probably some other stuff.

well biked

The reason I used WD-40 was that I've had good success, as have many others, using it to flush out Shimano shifters that have the dead shifter syndrome (you shift them, nothing happens). A fair argument could probably be made that by using WD-40, you're dilluting the factory lube in the shifters, but whatever the WD-40 does in there, it doesn't seem to hurt anything.

You could use another lube after flushing them, or just use something like Tri-Flo or similar to do the flushing instead of WD-40. I do know that I've flushed out a bunch of Shimano shifters, both road and mountain, with WD-40, and they work fine for a long time afterwards. I've not used a "real lube" afterwards. This includes shifters on my own bikes.

canam73

Ok, thanks. WD-40 it is then.

GT85, love the stuff!

Don't own a single can of WD-40 in all of the lubes I own. AFAIK, SRAM does supply rebuild parts at least for Red. You might look around if a good hosing out with lube didn't help.

They are rebuildable, and they're not that hard to work on either. I'd love to back this up somehow with service instructions, parts availability, or exploded views, but I can't find any anywhere. I learned how to do it by demonstration. I've never been required to rebuild one though, so I'm not sure what, if any, internal parts SRAM offers.

Anyone else had to do a rebuild on these and gotten the parts from SRAM to do so?
