Continental bike tires
I am planning on buying the Continental 5000 bike tires at Amazon: https://www.amazon.com/Continental-U...8-4&th=1&psc=1
I am confused as to the additional choices of 48 mm, 80 mm, and 60 mm. What do these refer to.
Thank you in advance

THe link is to a tire+ inner tube set. The 48/60 etc. number is the length of the valve stem. If you have shallow rims you can use a short valve stem, if you have deeper aero wheels you should get a longer valve stem.

Thank you for your quick response.
If all 3 will work, does it make any difference performance-wise which one to choose?

I can't imagine valve stem length having any appreciable impact on performance, but make note, the stem needs at least be long enough to clear your rim depth.

I'm kidding but no, valve stem length won't make a difference.

If you have a shallow rim, it might be beneficial to use a shorter valve stem because a longer valve stem may put more force on its base when pumping, and this is a common spot for failures of tubes. In terms of performance I am sure there is zero difference, as long as your valve stem is long enough to easily connect to your pump.

If all the choices are the same price, I want more stem for my money!
More IS better

long stems look stupid. And they weigh more. So keep it short.
but you don’t want them too short because then you can’t get some pump heads on the valve.
as for aerodynamics, just leave the cap off and you’ll be fine.
any discussion about the retaining nut, if the valve has the threads for it should be a separate 10 page thread.

Long valve stems are totally un-aero and are the reason you're not winning the traffic light sprints...
Check out the INEOS marginal gain of hiding most of the exposed valve stem with a detachable deep section wheel cut-out thingo-ma-jig.

But in all seriousness, as long as you have enough valve stem protruding above the rim so you can attach your pump / C02 inflator you will be fine. Make sure your spare tube does too!

If you're using very tight wired-on clinchers then a long valve stem on a 'short' rim makes things a bit more fiddly when trying to get the inner tube out when you puncture.
