* Presta is the most common and found on all road bikes, and most gravel bikes. They require the smallest hole in the rim, as
they are the narrowest valve, and need the end to be unscrewed before they can be inflated.
* Schrader valves are the same as most car and motorbike tyres. Larger in diameter, they require a bigger opening in the rim than
Presta valves. They are slightly sturdier, with no fragile end, so are typically found on mountain and hybrid bikes.
* Woods (or Dunlop) valves have the same diameter valve as Schrader, but use a removable flange to secure the valve in place.
These are all but obsolete now and are very unlikely to come on any new bike, so best not to worry about them.

If you’ve got deep section, aerodynamic rims, you’ll need a longer valve so there’s enough protruding from the rim to attach a pump to.
There’s no standard as to how much longer a valve will need to be, but 60-80mm valves will work for more aero wheels. For comparison, a standard valve tends to be around 40mm.
If your rims are really, really deep you’ll need to get a valve extender. These little widgets screw onto the end of a normal
valve to add extra length, but can be fiddly to use.
Make sure that you’ve got the right length valve to suit your wheel depth to avoid getting stranded.
