Prestacycle Presta Head

I pump my bicycle tires before every ride because I know how important it is to have proper tire pressure, not only for performance but also to avoid flats and tire failure. Back in the day, I used to use a Silca Track Pump that had a similar head, which was super easy to use, and worked very well. Prestacycle EZ-Grip Big Presta Head with the Urethane Elastomer gasket is just as easy to use, but it seals better, and I think the gasket will last longer. I have been using it for almost three months now and couldn't be happier. I have used many pump heads over the years, but I'll stick with this one from now on.

So this has some sort of soft "putty" which is supposed to hug the valve stem when it's inserted. The thing is, after a couple dozen insertions, it loses its shape and no longer creates a good seal. I thought of some ways to replace it, and came up with this solution: Go to homedepot and in the sink/faucet section, pick up a pack of 3/8" diameter washers. 3/8" OD is a bit large, so i put it on a drill bit and sanded it down until it fit (it helps if you sand a slight taper while doing so). I replaced the cap and gave it a try. It's a snug fit and some stems might be difficult to pull off, but it seems to work fine. I can't gauge long-term usage, but if the washer goes bad, I'll just replace it (a 10-pack of washers is around $2.50). Give it a try!

Well built. Stays put when pushed onto the valve stem. And no leaks while filling the tire. I use it with a battery powered air pump and it perfectly converts the pump’s Schrader connector to Presta. I’ll be ordering another to keep in my tool kit.

So far it works great. The whole set up is a little bulky, having this unit attached to the universal head. Additionally, if attached to a pressure gauge will only show the tire pressure if air is added. But its worth the cost of not leaking and being easy to attach to the presta valve.

OVERPRICED FOR WHAT YOU GET - IF YOU REALLY RECEIVE A COMPLETE ITEM. I ordered the Prestacycle Big Presta Head. It arrived as a shell only - missing parts. Considering the price you'd think that Prestacycle would have better QC, or at least respond to my efforts to get the missing parts. Nope.I bought this to make a complete Presta tire inflator with some inexpensive made-in-china parts. The complete Prestacycle Presta tire inflator is way too expensive for what you get. In fact, I had one and the hose disintegrated. I was buying made-in-china parts to make my own and avoid the lousy Prestacycle version. I know not everyone is a DIY-er, but avoiding overpriced and defective Prestacycle parts is the way to go!By the way, I tried to contact Prestacycle for the parts to make it whole. There is no phone # on their website. So twice I used the only communication they offer - an online form. Twice I was ignored. DEAD SILENCE! Overpriced products and zero customer service? Look elsewhere.
