Valve stem hole diameter?

[stevepsd]

For anyone who has replaced their tires: do you know the diameter of the valve stem hole (front & rear) on the ST? Looking to replace the rubber stems with 90 degree metal units. Want to get the correct ones ordered up ahead of time.

Thanks!

I would call them the 'standard' size. How many sizes do you find listed? There's an old school 'fat' stem, the standard, and some racing bicycles use a real tiny specialty stem. That's all I've come across in 20 some-odd years of wrenching. There are all sorts of lengths and angles though. Most metal stems come with two gaskets, one for the standard, and one for the old school fat stem.

Looks like Bike Bandit has some information but not definite answers. I checked the service manual but did not find the size for the Tenere.
