Downtube shifter keeps moving

The shifter that controls the chainset side keeps moving back after 5 seconds of cycling. Really bugging me. Took it to a guy who inspected it for a few mins said it was strange for it to be happening. It has been tightened.

He said there is a possibility that maybe the washer might be broken or something?

I'm not really experienced with tube shifters, any ideas?

My baby...

^nice bike!
The shifter needs friction to work, so may be oily, or the friction washer (a plastic one usually) might be worn. Take it apart, carefully, clean it with detergent or something and put it back together and see if that helps. Sometimes the outer part cracks, and then won't apply any pressure. Second hand shifters are pretty cheap if you need a new one

I grease the inboard washer and the stud itself to prevent corrosion due to water ingress, but not the friction washer. Just a very light smearing of grease - wiping it with greasy fingers is enough.

Thanks for the compliment. My bike is sexy.

Many thanks! =]

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

Just like Github, a blank line must precede a code block.
