Who makes/sells a Presta air chuck?(15 posts)

Who makes/sells a Presta air chuck?Humma Hah

I'm not referring to the Schrader/Presta adapters in a jar by the cash register at the LBS, I'm talking about a proper air chuck to snap into the air line from my compressor at home.

I'm sitting there pumping furiously with the minipump to inflate my tires, staring balefully at the compressor sitting 5 feet away, wondering when it is going to start earning its keep. I'm spoiled by being able to fill the Schrader-valve tires this way on everything else in the garage.

I made my own by adapting a Silca head onto a hose fitting with a gauge that was designed for Schrader valves.

The QBP catalogue has what I can only assume is a real nice one. It has a gauge and a bleeder valve and works with either Schrader or Presta valves. Cost is $75.00. That's wholesale so expect to pay more at your LBS.
Mmmm ... Performance is listing Silca heads for about $9 ...Humma Hah

... or less. Curious that when I was in there Saturday, the guys in the shop swore there was no such product available.

I just found mention of Silca products in a web search that turned up a discussion on another cycling board. Looks like its about the only line on the market for this application. Also looks kinda big, and I hope I can get it in on my 36-spoke wheels. Have you noticed any problem with this?

I think you've got the right idea on how to rig it, as long as the gage is a high-pressure range. My compressor has a regulator and I can set it up to something around 120 psi, but I don't trust it entirely.
Silca is the productKerry

All you need is a Tee from your hardware store, a gauge with a hose nipple fitting, a couple of short pieces of pressure hose (also at the hardware store) and three hose clamps. If you put 12" or so of hose after the gauge then you'll have some flexibility with the chuck. And while you're shoping around, find a new bike shop, as yours appears to be asymtotic to clueless.

I vote for a good floor pump.
You miss the point ...Humma Hah

I've got a tolerably good floor pump, which can fill the tires in short order. But I've got a bad case of TimTheToolmanitis. Power -- urrr -- must ... use ... compressor.

I'll ride a bike under my own power for 150+ miles, but operate a hand pump when a perfectly good power tool is handy? Obscene!

Would the adapters you mention in your original post actually work with the air compressor?
You mean the LBS adapters?Humma Hah

... I'm not really sure. I believe they're intended to screw in on both the Presta stem and the Schrader chuck, and the Schrader chucks I own and at the service station are not of the threaded type.

I was looking for a quality fit, something that would fill the tires without leaking all over the place. The Silca's appear to be more suitable than anything else, but I'll have to try them to see.

I bought one of those brass colored adapters for a couple of bucks years ago. Haven't used it much, but figured I might need it in case of emergency and the only pump avail was a Schraeder.

Anyway, maybe it will work for you, even if it ain't the greatest seal. Hopefully you'll find what you're really looking for. Otherwise, you have to decide if it is worth using the cheap adapter w/ the air compressor versus pumping by hand.
actually that is my point...desmo

Alas, this IS the new bike shop!Humma Hah

Now, you wanna talk clueless, you should see the LAST one. Never, in a year and a half, got an order right. I gave 'em every chance, not wanting to cave in and shop at Performance. The last straw was the custom wheel -- first they managed to order a 650c rim instead of 700c, then they built it up on a 130mm axel rather than the 120 I'd specifically ordered. I made 'em eat it.

That's the sum total of bike shops anywhere nearby. I really miss my LBS in San Diego -- elitist snobs, but they new their stuff, and finally warmed up and humored me.

I looked at the picture on the Performance website. Does the other end of that Presta chuck insert (and fit) in standard size air hose and seal with a clamp? Does the Silca chuck have an o-ring to seal to the valve? How well does it work?

The cheapies screw onto the presta stem. I hate them because, about half the time, I manage to screw the little presta stem nut back in when I install the adaptor.

The Silca chuck is a big brass thing that press fits onto the presta stem. It's not so big that fitting between the spokes is an issue. It fits my 40 spoke tandem road wheels with room to spare. It has a threaded fitting to adjust the tightness of the press fit onto the valve stem.
