Wheels Mfg Presta Stem Savers(Return to Product Page)

Got these to extend the life of my old Mavic Rims fitted for Schraeder valves. With these, I can just grab a spare tube and go for a spin on either my vintage bike my newer road bike without worrying whether I grabbed the right one. Simple and effective.

turned my schrader drilled rim to presta. No problems. no rattling stem now.

I've been using tires & tubes with Presta valves since the mid-1970s and prefer them over Schrader valves. The Stem Savers allow me to switch to tubes with Presta valves and not have worry that the larger hole for the Schrader valves cutting will into the tube and causing a leak.

Replaced rotted rubber savers with thees metal very nice

great solution to add presta to a schrader hole.

Have used these at adapters for Schraeder valves but they're great for adapting touring racks to 120-126 rear triangles and helping to pinch fender bolt tabs to eyelets.

These come in two per package, in case that wasn't clear. And they work as promised! I put them in my vintage hook-less rims.

These do the job, but should be anodized for corrosion protection. I just had to replace a tube after a pinch flat, and could not get the corroded stem saver off the old stem...corrosion was so strong that the stem ripped out of the damaged tube, as I tried to remove the stem saver. I had to limp home with low pressure to prevent the new presta tube from extruding through the Schrader hole.

All I have to say is I'm glad I switched to presta valve tubes using these stem savers on my 1979 Takara Sport Road Bicycle, because I use a pair of 28mm Continental Super Sport Plus tires that require a maximum pressure of 115 psi.

Not much to say. They do what they are supposed to do.

Nothing not to like. Gets the job done, does it well, and doesn't cost much. I see no downside to using these, and I can run the same valve front and rear.

They work, and the price ins't too bad, but they could be done better. The rim at the end made too much bulk around the valve hole where the rim tape is already doubled, and the thick stem to tube connection is. I slid the adapters on from the outside, and tightened down the nut on the presta stem to hold it in place. They could stand to be bit longer too. They come shrin wrapped to a card and the plastic is very difficult to get off, I had to scrape it away with a knife. Not bad product, but there's room to iprove.

I wanted to convert my rims to Presta and these stem savers did the trick. They fit perfectly and do not block the valve in any way.

Great product to convert my travel trailer tubes. They are easy to install and hold the valve securely.

They work like they are supposed to. Helps to put a drop of super glue to hold them in place when installing.

I've used rubber grommets before, but these are much better. Won't break down or wear out like rubber.

Exactly as advertised, promptly shipped and received. Great item, experience and Seller.

I converted my daughters 20 in. bike to Presta using these and now I don't need to worry converting the frame pump on my bike to Schrader. One stem for everybody and one less thing for me to worry about. That's worth the price right there.

Used these on an older Trek hybrid bike that has 700cc tires but holes for schrader valves. Fits perfect and works as advertised. Don't need to worry about 'aneurisms' anymore.

This product works prefect to switch over to Presta from our Schrader valves.

Enough said!
