I needed this to for a kids mountain bike (schrader valve). Did not work. Was not worth my time to return it.

I run Schrader tubes on most of my bikes, and own a nice Schrader pump with a built in pressure gauge. My newly refurbished vintage Raleigh road bike, however, runs Presta tubes and the rims are too narrow for me to drill them out to fit Schrader. I really didn't want to buy a new pump, and was having trouble finding one I liked anyway; so I figured I'd these adapters.These adapters are well-made and sturdy. All of the threads fit appropriately, and the o-rings provide an air tight seal. More importantly, they allow me to use my Schrader pump on my Presta tubes. I ended up buying two sets because I kind of assumed these would be poorly made. I was wrong! BUT now I have a shop set and a travel set.My only complaint is that the o-ring doesn't stay seated in the Schrader-to-Presta adapter, so if you're not careful during removal of the adapter, you'll lose it. Otherwise, these are a 5 out of 5.

Both adapters worked well with all the pumps I've tried them with so far. I'm not sure what the longer Presta valve expansion adapter is for, but the two parts I care about are fully functional. I store the two adapters together in my bike pouch along with a patch kit for extra versatility on rides.Presta Tire Valve to Schrader Pump:Open the tire's presta valve fully, then carefully slip the copper adapter past the valve and onto the threads to not lose air before pumping. From there, get the adapter finger-tight so the valve can be pressed by the pump pin.This adapter doesn't leak air when attached, so it could be stored on the stem when not in use. However, I would recommend taking it off and closing the presta valve when it's not being used to prevent the presta valve from leaking since they can be a little touchy when open.Schrader Tire Valve to Presta Pump:This adapter slowly releases air while it's attached, so have your pump ready to go if you don't want to lose air before pumping. This also means it can't be left on the valve stem when not in use. Once the adapter is installed, you can put your finger over the presta hole to prevent air from seeping out before you attach the pump. Once the tire is inflated, remove the pump and put your finger over the hole while unscrewing the adapter to prevent unnecessary air loss.

Buy a fancy bike pump that only works with presta valves only to come home and see you have a schrader? Well that's what I did, and this works fine. The schrader -> presta adapter does let some air out. But if I had wanted peak performance out of my bike, I wouldn't be such a cheapskate would I?

Good quality. Economic price. Twice the value. Fits my road bike and my mountain bike. Not to mention the many other inflatable items around the household.
