I usually only use the left shifter once or twice during a ride. This morning I went to shift into the big ring and after I left go it shifted right back into the small ring. The detents on the shifter were not catching. After trying a bunch of times I have one of the detents back. I'm using the Goretex cables which are know to peal. I need to look at it later but I suspect its pieces of the cable coating that I'm going to need to clean out of the shifter.

Anybody else ever had this issue or any other thoughts on this?

Make sure your cable doesn't have too much tension in it.

yep. tension and junk can do it. should "develope" that problem though. I would read run the front mech cable. free it completely, operate the lever a few times to get any junk out and then run a new cable.

i'm having a slightly different issue. i have the 2013 levers - and the paddle on my left shifter seems loose. lots of play. it wiggles everywhere. seems sloppy. 'zero loss' doesn't seem very accurate in my case as i have to throw the leaver quite far to shift to the big ring. down shifting is no prob. is there a way to tighten it up?

Zero-loss means that the paddle starts moving the derailleur with no dead space. You still have to move it all the way over to get a full upshift, but you have no "dead movement" like on Shimano, Campy, and lower Sram components where you can wiggle the paddle without affecting the cable/derailleur at all.

If you are able to move your left paddle while the chain is in the small ring, and you can do it without getting any resistance or moving the cable, something is VERY wrong.

I get home last evening and put the bike on the stand ready to get some work done. The bike repeatedly shifted perfect. :? Today's training ride will tell the story. If all goes well I will change the cable anyway this weekend since I do not want a repeat issue with this.

I hate it when I cannot repeat the issue when home. This is quite annoying and happens more often than not...

I am not so lucky. Turns out something is VERY wrong.
