Brass Presta Valve Adaptor (Pack of 5 + 10 Caps) - Convert Presta to Schrader for All Types of Bikes, e-Bikes, and e-Scooters - Inflate Tire Using Standard Pump or Air Compressor - by Mobi Lock

Great work it works

I keep some in the toolbox and some in the glove box. They work great!

Worked well super easy to use and very convenient 👍

Prompt delivery, good product. Only negative is the inability to mount them upside down to prevent accidental contact and loss of air

Had to order this item because it came with a cap. The least expensive one that I previously purchased did not come with a cap. After numerous exchange of releasing and putting air in the tires, the rubber cap wears. I noticed that a small amount of air are release. Also, I had to replace one tire tube because the valve broke. The rubber cap adds additional protection.

Have a 3 wheel recumbent bike with Presta valves and wanted to be able to inflate them at home and away using Schrader nozzles. I don't leave them on but carry them in a small container to use when necessary. They seal fine for filling and are well made from brass with an o-ring so they will last a good long time. The extra caps are always handy and add extra functionality to the package. Good value for the money.

Very nice pack.

We were having a terrible time finding a pump that would work easily with the Presta valve on our new bike. These adapters worked like a charm!
