noticed lately that a few carbon rims are not showing the valve outside of the rims. those rims where clinchers. do the work with a valve extension wich is removed after inflating ? does the vlave than stay opened, when the extension is removed ? wont it loose pressure thru vibriation ...

Zipp valve extenders intended mode of operation is to undo the locking nut on the valve stem, then screw the extender onto the valve.

The locking nut is therefore unlocked all the time.

I had these on my old wheels, can't say I ever noticed them going down faster than any other butyl-tubed wheelset.

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

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