|On the last 10 miles of a 70 miler this AM, my right lever started a scraping sound when I shifted from a small to big cog. So, I quit shifting. I road the last 10 miles in my 53/19 or 39/19. A pain on the hills.
Apparently, the shifter needed some lube. I put a few drops of tri-flow into the guts, shifted a few times, and all sounded good. Here's the question....is tri-flow OK?? or should I put some lithium grease in there??? Should I use my air compressor to blow out any junk in there, then start over with the lube?
P.S. The first 60 was great - 45-60 degrees, avg'ed around 17.5 alone over steep hills, but that last 10 stuck in one gear killed me. stick a fork in me, I'm done.

|Give it a heavy spray with something real thin, like Slick 50 1-lube. This stuff is not harmful to plastics. Might need to take the lever off to do this, or you'll have lube on the bar tape. Best to remove the brake hood also.|

|That's solid advice! Only thing I can add is maybe using GT-85. I have used it in the past in a 9 speed Chorus lever.. worked fine. Also used it in my old Dura-Ace levers with no problems.

|TriFlow is a good lube for Campy Ergo levers - it thins the grease and spreads it around. I'm having a hard time relating to the noise you heard - you sure it wasn't the derailleur making the noise? At any rate, don't blow things out with an air compressor, since you might actually force crap deeper into the mechanism. Standard rejuvination for the levers is to peel back the hood and squirt a thin lube (TriFlow, ProLink, etc.) down the little hole while shifting repeatedly through the gears. Not a few drops, but so the lever is dripping. Works like a charm. If you are adventureous, you can take the thing apart and re-grease, but that doesn't need to be done very often, while the "thin lube" thing may be required a couple of times per year.|

|I don't know where the sound came from either. It was very sudden...one shift OK, the next ...scrrrraaapppe.... But the tri-flow did the trick. I'll flood it tonight. Thanks. Paul|

|Sometimes a single strand of the derailleur cable can break, unwind, and get bunched up, causing the scrape. Once you shift hard and push the bunched up cable strand down the line, away from moving parts.|

|Yesterday, I only had time to flood the shifter with tri-flow and do several shifts. It looks like I will have to re-adjust the derailleur becuase the shifting is off. I recabled the bike last summer, so I hope I don't have to do it again. I'll admit, the scraping sound has me bothered too. Can it be that one minute the lube was OK, then next...gone?? Strange. But once I heard the sound, I stopped shifting. Period. Another record shifter is a lot more costly than the pain in my thighs and calves for ten miles.
Better to have this happen now versus a couple weeks from now. I'm doing back to back centuries over mother's day weekend.
