Are the Presta valve stems threaded? I suspect the photo shows the Schrader valve version.

Arn't presta valve stems always threaded? Our order was for Schrader valve.

From the pump description provided via Amazon: "....to configure the pump head for either Presta or Schrader valve stems...." You will find specific directions on the manufacturer's Geared2U website.

you can put tubes containing either presta or schroder valves in these tires

a Schrader valve is what you're used to; it's on your cars and bikes, normally. The presta valve would normally need an adapter to add air. You can Google images of presta and schrader. I suspect that schrader is what you would want.

Yes. All the 700C sized wheels I've ever seen have a presta sized valve stem hole. I had to do some very minor trueing.

There is an attachment on the tip where you can switch it between presta and schrader. All the parts should be in there! I had to mess around with both bike tires (one of each kind) to figure it out but it works!

Yes, you can switch back and forth between schraeder and presta valves. Just unscrew the headpiece and flip the inside housing. I do it all the time and one reason I like the pump.

The fitting must have threads around the valve as this is intended for R12/22 style schrader valves. Modern R134a systems use a different "snap-on" schrader valve.

I believe the ball valve is threaded. But I would assume if you wanted to use hoses you would need an adapter with a "spigot" tip to get hoses put on.

This is only set up for Schrader valves. You may be able to find an adapter though.

I am using presta, but the size of the hole in the rim is irrelevant. The valves are different, but the presta body is the same size at the base as the schraeder. So either one will fit.

My bicycle uses Schrader. I would go by the description/page title, since the image looks like a generic Google search image. I bought these a pretty long time ago, so the item may have changed.

The threaded stem is the same size as the stem it goes over, the tire stem. Your valve cap will fit on, your pump will fit etc.It is a standard schrader valve size, 8mm diameter

No, you should not drill out the hole to fit a Schrader valve. Where the hole is drilled for the valve is the weakest part of the rim, and drilling out would almost guarantee failure. The whole point of presta valves is that they are smaller diameter and can do with a smaller hole, leave more metal, and do with a narrower and lighter rim. If these were made of steel, I would say that it might be possible, but they are an aluminum alloy. I bought these and was tempted to drill them out since I didn't have presta valve inner tubes on hand, and I'm glad I didn't. I ordered thick puncture resistant presta valve inner tubes and put Continental Gatorhardshell tires on them, and I haven't had any problems at all with this combination after about 1000 miles.

I assume you mean presta valves vs. schrader valves (shrader=standard car tire valve). It adapts to both - the head unscrews and you can flip the bits inside to make it compatible with either valve type.

No but it can easily be modified to fill Presta Valves.See my comment below.

Yes, the pump will work with both Presta & Schrader valves. Just need to follow the instructions and switch over the attachment connector.
