I wish I could give these adapters 6 stars. I recently went to tubeless and got stuck with presta valves. It's been 20 years and I forgot how much they suck! The simple brass adapters you see all over the place do not have a schrader core and really only let you use an air compressor. You can't use schrader gauges and hand pumps are iffy with those type. These are the only adapters that properly convert to schrader by ditching the presta core and allow you to use all schrader gauges and fill chucks. Yes you need to have removable core presta valves, but if you are running tubeless this is almost a sure thing.
Hate presta valves, or only have a Schrader pump, or want easier tubeless setups (using normal compressor head)? BUY THESE. You remove the presta valve core and then screw these on, they then act like normal schrader valves do. I've used these converters a few times now and they were worth every penny! They allow plenty of air volume through to seat even my most stubborn tubeless tires, they're easy to use, and you can leave them on if you want. I wish I had found these a long time ago.
These converters are super easy to install. I love the fact that I don't have to use a special adapter on my inflater anymore. I bought sets for 2 of my bikes, and love the first set I have installed. They don't add too much length to my stems, and feel like they are really well made.
These work just as intended. Remove the valve core from your Presta valve, screw these things on and voila! Now you’ve got a Schrader attachment. I used these to set up some tubeless tires and they worked great.
Great product that allows the conversion from priests to Schrader valve.
Excellent product, as advertised! Makes inflating tires so much easier than with presta valves.
This was exactly what I needed. It doesn't leak and now I can use a normal schrader valve. Works perfectly.
These are perfectly great, but I needed the reverse product. Schrader to Presta. Make sure you know what you need before ordering.
Purchased to change my trike's presta valves to schrader, so as to make it easier to fill my tires, which it did, no problems.
This is a great product that converts the unuser friendly french presta valves into the easy to use american schrader valve. Love it!
