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.

Hi Mark, for a presta valve, you need to buy a presta attachment. You should be able to pick these up at any sporting goods store. They are cheap and screw right on and convert it to a schrader valve. Presta Adapter

Threads. but not sure what you mean about inside the valves, all is threaded on

There is a small gauge in the black portion that sticks off of the valve attachment. I found when using it with my schrader valves it is not always the most accurate.

The wheel allows for both presta and schraeder valves. I'm currently running a presta on mine.

If you have a schrader valve on your bicycle, it should work. Definitely will not work on presta valves.

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 connections are threaded. You should be able to elbow the piping over and even down, doing your valves on the horizontal or in other space you create by laying out the piping to do so.

Can a SELLER please answer this question??? where are the sellers that want our money? I agree with you: a 700C is supposed to be drilled for Presta, but in the pictures it definitely looks like Schraeder.

RORO, I honestly have no idea. After some of the trouble I've caused myself by buying this particular product (only because I should have got tubes with a straight valve stem) I still can't complain about their quality. They still work just like they did when I installed them on my riding lawnmower.

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.

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

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

Yes it does. They are slightly different than the stock ones, but they threaded nicely.

You switch around the internal pieces... In my experience it works much better for schrader... Presta is kinda funny on this pump... I returned this item.

I couldn't tell you for sure. My rockshox has a Schrader type valve that's threaded on.

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.
