How do you use the "Reversible Presta and Schrader valve attachment"?
1742303
Unscrew the cap on the valve attachment. Pull out the adapter inside and reverse its position (turn it around). Replace the cap.

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

The easiest thing to do for presta valves is to just get the cheap adapters that fit over the valve. These work fine and you don't have to modify the pump, which you may want to use for car tires also. Presta Adapter

Yes will work on both presta and schrader valves. Does not screw on - just a press fit.

You just push the presta valve in there and turn the black notched part to fasten it. You won't get any click or indication it's locked in, and it won't stop turning but it'll work. No conversion tool needed.

Works best on a standard (Schrader) valve. The cap has a little tool built in to take the valve stem out and it is very easy to do. Presta valve stems are a little harder to do because you need an adapter (about $3 at Sports Authority) on it to pump the slime into the tube but is very do-able.

Hi Pat,If you unscrew the nut on the head of the pump and remove it a rubber bush will be exposed which should also be removed together with the plastic valve behind the bush. Turn both the valve and the bush 180 degrees around and re-insert the valve followed by the bush so that the bush has the smaller diameter hole facing outwards to fit onto your smaller Presta valve. Then re-screw on the silver nut, with the dustcap attached, back onto the pump. The pump should now be able to inflate your Presta Valves.If you still are having a problem, have a look on YouTube as there are quite a few video clips on there that show this being done.

I bought these for my son, so I have no first hand knowledge. Jusr asked him...he says the valve is Presta.

Sorry. Don't use a presta valve. But this is a conventional clip-on inflator, so you would likely need an adapter of some sort.

Presta adapters don't go into the head far enough to open the valve. I'm trying to find a solution myself as well!

Its both. The default is presta, and its schrader once you remove a smal plastic ring.

On the lower section of the valve there is a hook lever, pull that up, rotate the lower section of the valve to free it, then adjust it up or down as required. When done, rotate it back until the hook lever clicks.

Greetings, the valve stem length is just less than 1 1/2" on both the schrader & the presto valves. I suggest you stick with the reg. tube. The thorn resistant tube seems to always fail at the valve stem base . Just my experience .

This particular model had presta valves and the stems were threaded. I've also bought them for schrader valves and the stems were smooth.

I ordered tube with presta valve ASIN: B000ENMLFK Item model number: 123925. You can use these numbers to cross reference. Hope this helps.

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.

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