Prestacycle Presta Head

I have this on my compressor (the head has Schrader threaded fitting, which screws into an air gun nozzle), which I use to seat tubeless tires and it works with zero issues. It's actually brilliant: no levers or threads to screw onto, grabs onto the valve stem as advertised, simple push/pull operation. It seals just fine over 70 psi I use to seat road tires. Initially I was also using it with my regular tire inflator, but replaced it there with the same design but better look and finish head from the pretentious bike accessory company I should not mention here. It worked just as well but was a little bit too big. My inflator has constant airflow and a cut off pressure setting though, this design might not be that good for manual pumps with analog manometers.

So, there are a lot of "misinformed" reviews here. Part of it is the lack of info on the product page & the PrestaCycle website. But some is just a misunderstanding of what this adapter is for. This is a Presta valve adapter. It is not intended for a Shrader valve (found on cars and many bikes). The Presta valve is found on many road bikes and others with thinner and/or high pressure tires. The Schrader valve is the one with a pin in the center that you depress to fill or let air out. The Presta valve you have to unscrew to fill or let air out, but the pump head does not press a pin or anything to fill the tire. The threads on the adapter are the same as most bike pumps with Schrader valves, so you can put this on a Schrader pump head and use it on a Presta valve. Since it is a "press-fit" device there is probably a limit as to how much air you can get into a Presta valve tire without it popping off. Ok for low pressure bike tires, but not the best solution for high pressure road bike tires. Best way to use this, is to use it with a compressor or air tank, and put it on a trigger as shown in the picture. The trigger generally comes with a short threaded tube piece that this adapter will screw into. They can be had here or your local hardware store, make sure it has the small threaded tube piece. https://www.amazon.com/WYNNsky-Fittings-Compressor-Connect-20-Piece/dp/B06W9DSRYP/ref=sr_1_48?dchild=1&keywords=hand+trigger+for+air+compressor&qid=1601560538&sr=8-48 This setup is great for tubeless tires to set the bead. With a compressor you can set pressure limit regulator so you don't burst the tire. With a tank you are limited to how much air & pressure the tank will hold. The triggers also typically have a 90 psi rating, so that is a factor too. I use this exclusively to set beads on my tubeless bike tires. Final inflation I use a proper Presta valve pump. Too much chance of overinflating a tire with a high psi compressor. I guess the small electric inflators would be ok, but they would not work for setting beads on tubeless tires. So...that's probably the definition of TMI, but I was bored today and thought there were too many incorrect reviews for this for this otherwise good product...:)

I can't find a fitting for this Presta Head to attach to my compressor. The Presta Head is metric. I searched all over for an adapter, but couldn't find one. All the pneumatic fittings I found are Imperial standard based (that's what America uses). The company knew this was a problem because they now advertises a Presta Head with a compressor fitting. Which costs an additional $12.95. THE BEST FEATURE - This head is perfect for Tubeless tires and any Presta valve. INCLUDES - Newest version of the Mini Presta Head Gasket using Urethane Elastomer. QUALITY - It lasts more than 5 times longer, gives a better seal and flexes to work anywhere along the Presta shaft for better tubeless tire application. PUSH ON/ PUSH off – The fastest way to get you going. COMPATIBILITY - Compatible with Silca pumps and can be adapted to other pump brands with our optional Schrader barb or our floor pump replacement hose. I'm done with it. Using $2 adapters from my local bike shop.

The adapter allows a regular manual tire pump to connect to the Presta valve. My first attempts have been difficult. The adapter fits in the tire pump but, after loosening the valve in the tire, the adapter does not easily press the valve down to allow air into the tire. Eventually it worked but I needed to ask another person to pump the air while I held the adapter in place. Other that that, it worked, filled the tire, is well make and appears durable.

Work great w a nice locking system and good seal

Yeah, it seems expensive yet soooooooo worth every penny. Using it on an electric air pump. So easy.

Sper produit je m'en passerais plus!

Makes it so much easier to pump up bike tires, especially with a Milwaukee air compressor.

Working great so far. Much easier than usual Shrader adapters.

For the life of me, I cannot get this to work. The valve simply is not actuated (pressed in) by anything, and air is prevented from entering the valve - thus it then blows out around the valve stem and anywhere else it can escape. Received today, going back today.

Die Polyurethandichtung ist weich wie Gummi und quillt beim Befüllen von Presta-Ventilen aus der Pumpenkopföffnung heraus. Kein Druckaufbau möglich. Habe die Öffnung mit einer Hart-PVC Scheibe auf 5 mm verkleinert und die Polyurethandichtung gegen eine passende Gummidichtung ausgetauscht. Jetzt erreiche ich problemlos 4-5 bar.
