It was the pump that the shaggy, unshaven mechanic at my local bike shop swore by. It was a battered-looking old beast that had once been a deep, burnt orange color -- now chipped and battle-scarred, peppered with rust. The foil sticker that once bore the brand was partially torn off: "ilca" it now read. But I could still make out the little Columbus tubing sticker near the base of it."Columbus tubing? On a pump?" I asked.
"It's the best" he replied with a shrug.
The thing was solid and substantial. He let me try it out, and I was amazed at the smoothness of it. Pumping a narrow racing tire up to 100 psi was nothing. The gauge went up to well over 200 -- not that you'd ever need to do that. But just knowing you could . . .
I don't remember how much a Silca Pista pump sold for back then, though I remember it was a bit more than my unemployed student budget at the time could afford. But I knew I'd have to get one some day.
When I was a student at Kent State, we were about 40 miles from Youngstown, which was the home of Bike Nashbar. Nashbar had a warehouse outlet where you could go and get great deals on over-stocks, closeouts, returned goods, and more. A bunch of my bike-mad friends and I would occasionally pick a Saturday to pile into somebody's car and take a trip to the warehouse to do some bargain hunting. During one of our visits, I found the Silca Pista pump -- in a very 80s shade of pink -- marked down 1/2 off. Nothing wrong with it. Apparently nobody wanted pink. My friends teased me about the color, but what did I care? I wanted a Silca pump, and now I could get one.
That was about 30 years ago, and I still have my "Miami Vice" pink Silca Pista pump. The pink paint is now battered and peppered with rust, not unlike the first one I ever saw, but the little Columbus tubing sticker is still there. The pump still works great.A few years ago my basement flooded, and the Silca was under water. It didn't work right after that, but the pump is totally rebuildable, and replacement parts are still available. A friend at my local bike shop had overhauled a couple of these in his time, so he took care of mine. He cleaned it all out, replaced the leather plunger, greased it up, and it was back to working like it should.
I still use it, though I've found (as many other cyclists have) that it is less than ideal for large-volume tires, like those on mountain bikes. It takes a lot (lots and lots) of pumping to fill a fat tire like that. No big deal. The larger "Super Pista" model apparently addresses that issue. It also is less than ideal when you need to switch over to schraeder-type valves, so I have a second pump out in the garage for the kids' bikes and the mountain bike. But the Silca is still my favorite, and is still there in my workshop, still pumping up tires on my classic road bikes. Something about it just feels right.
Silca Impero frame pumps were another classic bit of equipment. They were lightweight and easily fit along the seat tube or under the top tube. Like the Pista floor model, it was rebuildable. When it came to frame pumps, you either used the Zefal or the Silca. A lot of people swore by the Zefal. It was a little heavier (more metal, less plastic), and maybe even a little easier to use. The Silca took a little more "technique" to use, since the head didn't lock onto the valve stem like the Zefal's would. I figured it worked well enough to get you back on the road. What more did you need from a frame pump?
People would say the Zefal would last longer. But the Silca would last long enough if you didn't abuse it. And it was the classic choice. It came in a lot of colors, and many frame builders would paint them to match a custom frame. They didn't seem to do that with the Zefals so much. And Campagnolo made a chromed steel pump head for the Silca -- which was a cool bonus. The stock plastic head on the Silca was alright, but the Campy head looked better and would last indefinitely -- probably longer than the pump. I broke a Silca frame pump once -- cracked it over the head of a pursuing dog. I took the Campy head off and installed it on a new pump, which I still have. Someone told me once that the Zefal wouldn't have broken. Maybe not -- but it probably would have dented. How well would it work after that? Maybe OK, who knows?
The Impero frame pumps were discontinued some years back, but finding new-old-stock ones doesn't seem to be too difficult. I know there are some online bike shops that still list them for sale, and I've even been in a few older bike shops that had a big box of them tucked away in the back, and in a variety of lengths. The chromed Campagnolo heads still come up now and then on the vintage market. So it's still possible for lovers of the classics to keep using this blast from the past, and to keep them working like new.A Little History:
The Silca company was founded in 1917 by Felice Sacchi in Italy. The Sacchi family, from son Giancarlo, through grandson Claudio, continued to own the company right into the first part of this millennium, making it the oldest company in the bicycling industry to be run continuously by a single family. The company claims to be the first to incorporate a pressure gauge into the base of the pump, and the first to make a frame pump that didn't need add-on clips to attach to a bicycle frame.
Last year, Claudio Sacchi died of cancer, but shortly before he died, he sold the Silca company to Josh Poertner, a former engineer with Zipp carbon wheels. Poertner moved the age-old Italian company to Indianapolis, where he is gearing up to revive the company. Silca had been in decline in recent years, finding it difficult to compete in the modern market with so much Asian competition, and some of its standby products were dropped. According to an article in Bike Retailer and Industry News (BRAIN), Poertner plans to mix old and new, tradition and innovation, to bring the company back to the forefront. While the company continues to source parts for the vintage pumps, it seems they may not have plans to re-release new versions of the old classics. Oh well.
Poertner says the original Silca was about innovating, and he plans to respect that. One of the first things Poertner did was to introduce a new stainless steel version of the classic brass pump head with an elastomer gasket in place of the old rubber one -- it's supposed to provide a better seal while lasting longer. In the BRAIN article, he says the company is working on a new pump that he hopes will be "unlike any pump ever sold." I didn't know that tire inflation was something that needed cutting edge technology, but I'm glad I should still be able to get parts for my old favorites.
My biggest problem with the Impero was not cracking it over dogs heads (I know people who sharpened the Campy head's legs to facilitate it effectiveness in this off label use), but of the handle and plunger being shot out like a rocket when the internal chamber pressure became too high. The internal threading of the plastic cap seemed to be no match for the back pressure that sometimes built up within the pump. It was amazing how far these parts could fly! Fortunately no one, nor the pump were really injured in the process. I never had this happen with a Zefal, and eventually switched, but the Silca was certainly more elegant.
ReplyDeleteThat said, I have a Silca Pista pump from the 60s or 70s that still functions beautifully.
I have to admit, I've never seen the plunger shoot out of one -- but it's true that the pressure sure could build up, so I don't doubt it could happen.
DeleteIt's important not to push the head on too far, as there is no check valve in the pump if you push the head on far enough to open the valve on the tire. That's part of the technique mentioned in the article.
DeleteI have both the floor pump and the frame pump. I found that the threads on the plastic bushing at the top of the floor pump wore out, so I had to secure it from pulling out with 2 little screws. Also, I found the original gauge too small and hard to read, so I replaced it with a 2" industrial gauge.
ReplyDeleteThe frame pump was a replacement for one I lost and was too long. I shortened it the easy way by cutting down the barrel at the top and again securing the bushing with 2 small screws after sanding down the threads.
johnb - you are a problem-solver!
DeleteI have a Pista of about the same vintage and love the damn thing. Mine's pretty much identical to yours, but in black and lacking the Columbus decal. I replaced the screw-on chuck with a Hirame - super deluxe. About the only issue I have is with the plastic bushing at the top of the pump, but unlike johnb above, mine seems to be seized on - won't undo with fingers, and using something like vice-grips to loosen it seems risky, like I could crack it. Every now and then I squirt a bit of oil in through the breather hole and the leather plunger still seems to be making a good seal, but if I ever need to rebuild it I worry about that plastic bushing. Oh well, if past performance is any indication, this thing will outlive me.
ReplyDeleteGreat blog! I recently acquired the same Silca pump with the Columbus sticker. It has the reversible chuck, like the one in this blog? I'm having a lot of difficulty pumping my presta tire while holding the chuck with one hand and pump handle with the other. Any advice on the proper pumping technique?
ReplyDeleteIf the rubber gasket in the pump head (or chuck, if you prefer) is in good shape, it should press onto the presta stem and stay on without needing to be held. If it isn't staying put, it's possible the gasket is worn out - or it could be that you're not pushing it on far enough. If the gasket is worn, replacements are available on eBay, or direct from Silca.
DeleteWould you be able to tell me how to switch the pump head from my Impero from the stock head to a Campy one? Specifically, how do you remove the stock head? Thank you!!
ReplyDeleteIt actually just unscrews. Grip the end of the pump firmly, and twist the head off (lefty loosey, righty tighty!)
DeleteSome threads never die ... just one word of caution, there was a late version of the frame pumps that looked very much like the Impero, but which had a glued-on head that was not removable. Toward the end of the pump's production they also used a chromed plastic grip, and plastic threads on the pump body, which had a tendency to strip out.
DeleteI have perfected a technique of cutting down longer Imperos at the head end, turning the old barrel off in a lathe, and then gluing the plug back into the barrel. There are tricks that can be used to ensure that the pump logo is facing forward once the head is screwed on. Shortening the plunger to match is quite easy. Since I ride smaller than average frames, this has greatly expanded my choice of suitable pumps.
A trick I use to avoid launching the plunger of a Silca frame pump like a rocket is to place the end of the pump handle against the inside of my elbow while pushing the pump head onto a partially-inflated tire. It's not a problem if the tire is flat when you push the pimp head onto the valve, of course. I have many times had the pump push hard against my arm which positioning it on the valve, even though I almost always use Campy pump heads.
You can often find wooden handles for the pista pump on fleaBay, or if you have access to a wood lathe, turning a custom handle is an easy and fun project. If your pump has the oval plastic handle, do yourself a favor and replace it with a wider wooden one. It doubles the pump's functionality--no exaggeration. That plastic handle should never have been developed, In spite of its hose-keeper grooves (a neat idea that barely works).
