Pump it up!

I enjoy racing, and I enjoy training. But, I also really enjoy other parts of cycling, including the gear and the history.  So when I can pick up something that has some historic feel to it that is also pretty cool and as a bonus, quite useful... well I jump at the chance, especially if it's fairly cheap.

So, as you may know if you've read for a while, I like Silca pumps. The new Super Pista is a great bit of kit that I use every single day. In my garage I also have an older Super Pista (mid 2000's I'd guess) hooked up with a Hirame adapter I use on my race wheels. And just a couple weeks ago, I picked up an old (stamped 1989) Pista pump. With Silca re-releasing the Pista just recently, it seemed like a great time to snatch up a little piece of old school kit to play with.

This specific one was listed on ebay in non-working order. It seemed the previous owner had given up on it many years ago and it had sit in neglect since then. For $30 the majority of the pump was in great shape though, with some chipped paint (which adds to the panache of a pump like this in my opinion.) but otherwise pretty nice. Yellow is a flashy, nice color, probably my favorite behind Molteni Orange.

After it arrived I took stock of the problems. Primarily, it was simply that the leather washer had likely never been changed and had a couple of rips in it. The hose was in fairly good condition for it's age, but I added that to the list of replacement parts as well. Finally, the gauge. It seemed like it was still functioning, but without the pump working it wasn't possible to know if it was holding any accuracy... unfortunately it was almost certainly not after so many years, so a replacement gauge was the final piece. Fortunately Silca sells a rebuild kit for all their pumps, so it didn't take much work to get all the pieces necessary.

Once I rebuilt the pump I tested the accuracy of the gauge. Unfortunately it was, as expected, miles away from accurate, somewhere around 25psi different from my digital gauge. That was unfortunate, the replacement gauge from Silca certainly looks good (and more importantly, it matches the vintage look of the original) but I was a bit remiss that I would lose the sweet 240 max psi from the original. Sad, but function of fashion.

Very sad days... 16 bar is a nice inflated number (Oh I've got puns)

Once it was back together and freshly updated, it was time to put it to the test. How well did it work?

My super unscientific test. Blow up a 22mm Tubular from 0psi to 100psi with the three Silca pumps.

1989 Pista - 21 full strokes
circa 2000 Super Pista (w/Hirame) - 18 full strokes
current Super Pista - 13 full strokes

Generation gap!

No big surprises there, the longer the barrel, the less strokes required. It's also fair to say that the "feel" improves as they get newer. Nonetheless, the old Pista did a fine job pumping up the tire. For what is essentially a much good bit more portable pump it did what you'd want from a pump you threw in the back of the car.

So, a new toy to use. If it's like my other pumps it's in for a lot of use... err, more than it's seen in the past 30 years. I just thought I'd share it, I think it's great that Silca sells most of the parts to keep your pump running for a good long time... of course now I'm hoping I won't have to fall back on that for many, many years to come!

Thanks for reading, I really appreciate it!
