🚲 Combo Pack: 2 Presta to Schrader Brass Bike Valve Adaptors with Seal Rings - Conversion Adapter Converter for Bicycles Review

Great product, converts a presta valve into a schrader valve. I highly recommend it if you don't want to buy a dedicated air cartridge.

These presta valve adapters are well made and their threads are a perfect match for our air compressor hose. Due to the perfect fit, the bike's tires filled up quickly.

They fit and work well. The aluminum kit I had before had bad threads and came loose after a few fills. They felt a much more positive bite on the Presta valve. I would recommend closing the presta valve after filling and not relying on them to seal the hose.

Works great once you figure out the presta valve! I didn't even know there were different bicycle valves, but now I'm an expert! 🤓 A little advice for all beginners. Be sure to unscrew and loosen the small tip of the Presta valve BEFORE unscrewing the adapter. (This allows the air you inflate to actually get into the tire) 😜 Works like a charm!

This adapter easily attaches to an existing Presta valve but will not seal at higher pressures. This results in the tires being able to inflate to around 30-50psi, but after that air will seep into the back where the rubber O-rings are. This will work for a mountain bike or other bikes with low pressure tires, but if you have a road bike that requires 80+ psi, you might want to look elsewhere.

Perfect for what I needed them for. However, it is worth noting. I use an electric air compressor on my bike tires and at around 115-130psi my compressor head attached to the valve on my tire deflates due to the pressure. BUT, I'm still leaving 5 stars because I have absolutely no idea if it's my cheap air compressor or those adapters are the ones that are the problem, but either way they work great for what I need them for :)

I like these valve adapters and have bought several pairs - I don't like the valve adapters sold in bike shops. They are cheap, poorly made and often made of aluminum. The aluminum caps I bought are a real struggle to put the cap on as they are VERY cheap and the aluminum material is very low quality. The next problem to watch out for is that some valve adapters sold on the internet LOOK like they have threads but actually only have tabs to hold the tire pump head on the valve and nothing can…
