Valve Size

[Glasgow44]

Hi there

I'm looking at buying new inner tubes. What valve size should I buy? One valve picture is for my Bianchi and one for my Giant tubeless (I'd like to have tubes for the tubeless just in case):

Looks like 60mm length.

Looks like 60mm length.

For both the Bianchi and the Giant?

To be 100% sure remove both tubes and measure the valve lengths.

Valve extenders are very good and worth keeping in your tool bag. Just in case you are stuck with a short valve sometime.

I have a very very deep tri-spoke and the valve extender is kept attached all the time.

Measure the amount of valve sticking out, then add 10mm. Find nearest valve size to what you come up with.

A quick sanity check is to measure the depth of the rim, add 15mm to that and pick the closest.

@Ming the Merciless method would work on most rims around 23mm depth but wouldn't work on my 50mm rims.
