Presta or Schraeder Tube

OK this is probably a easy answered question, unfortunately I don't have it, noob here. I am putting a road pack together for my bike. I have 700x25c tires on it. While looking at tubes I noticed there are Presta and Schraeder valves. Do I need a specific one? If not what is the advantage of one over the other? Also I am assuming I need 700x25 tubes? Is this correct? TIA

Schraeder valves are the same size as car tyres so you'll be able to use air hoses at filling stations or car footpumps.

So, assumming here, they would be considered more versatile as far as being aired up. That's the only difference? Thanks!

Using an ar hose meant for a car can be a bad idea.

You can get adapters that let you fit Presta valves into Schraeder pump heads for about $1. Just check your rim hole, if it is 21/64" or so, it is Schraeder, Prestas are smaller.

The Presta valve is much skinnier than the Schraeder. So, if your rims are designed for a Presta valve, they will not accept the larger Schraeder valve. Chances are you need the Presta valve tube, which by the way, will fit a Schraeder rim.

So in my opinion, you can't go wrong with the Presta tube. Just make sure your pump is set up for Presta. And yes, the size tube you need is 700 X 25.
