A frame pump to fit a lonely head tube peg?

Hello.

I have recently acquired a 1994 Bridgestone RB-T and am a bit lost as to what pump would fit properly beneath the top tube into its single head tube peg.

I am familiar with a head tube peg and a 90º 'take up' peg which is brazed on beneath the top tube, but this single peg has confused my already befuddled mind.

Would anyone have a recommendation for a pump which fits this scenario? Leaving the peg lonely seems irresponsible—if not downright cruel.

They can be pricy but IMHO the best frame fit pump you can get is the Zefal HPX. They used to come in I believe 4 sizes to comfortable fit most any frame.


HPX - ZEFAL

Zefal HPX or a vintage Silca. The pump head wedges into the juncture of the seat tube and top tube, and the handle end is held by the little peg. You do need to get the length right. It was easier when you could just go to the bike shop and try one out to see if it fits. If that is an option for you, take it.

You should always use a velcro strap around the pump and top tube for safety when the pump is in this position, because they can fly off if you hit a big bump.

Thank you so much for the verification of this pump being something that would work properly.

(I saw this pump on Rivendell's site and concluded that the concave plane on both ends meant that it didn't fit a peg on one end, i.e. it was simply shoved between the tubes.)

And it can easily put 140psi in your tires if that's what you want. I have three or four of them.

If you have a co-op near you, those Zefal X/HPX pumps seem to collect like glitter. You'll wind up getting an older one, for sure (and they are schrader *or* presta, rather than both), but there is nothing to go wrong with them, and most work just fine despite being 10 or more years old.

The schrader internals can be easily adapted to presta by drilling the pin out of the middle.

I like the campagnolo head that fits the Impero (they made one that fits Zefal pumps, too, but the older model that pre-dates the X) better than the Zefal HPX head, since it looks a bit cleaner, but they are stupendously expensive, since you often have to buy both an old Impero *and* a Campagnolo head.

On the plus side, the Zefal pumps are built like tanks, so it evens out, I guess. You can polish the Zefals fairly effectively with a bit of determination.

You can get a new park frame pump that is adjustable to match almost any frame.

It's a good idea to measure the top tube before buying a pump. And you'll need to know how much the pump will compress. These pumps come in different sizes. You want the longest one that will fit.

Some of the old Zefal hp pumps, if Schraeder, you have to take out two pieces, both black, one soft rubber, one hard plastic. Remove (and save) the latter, and put the other back in backwards, and you now have a presta pump. Other pumps you reverse both pieces and put them back in.

That is the nice thing about knowing that the Topeak pump is available at a nearby shop: I can rest assured that the pump fits properly.

Though the idea @wschruba presented about digging through the vaults at Vulture Space is certainly worthy of consideration.

I just fret about looking foolish in front of these people in these shops so I am forever grateful for any assistance in augmenting my ignorance before confronting the hordes.

Despite having a bunch of Zefal HPs in different lengths and chuck I also have one of these. If I only could have one pump this would be it.

Oh, that is a lovely frame of reference, thank you for sharing the picture. I must admit that I have become rather enthusiastic about the RB-T and therefore seeing another one makes me smile. The bonus of getting a gauge on the pump idea is extra helpful.

Here is mine so far (the brakes and pedals arrive tomorrow):

Thank you for commenting on the bike

That is the Soma Oxford bar right side up. I toyed with idea of flipping it upside down, though I think I prefer this position for the time being. (The grips aren't glued on, so monkeying with bars shouldn't be too much of a hassle.)

Just FYI, this is a Zefal HP pump that I polished. The barrel took only a few minutes (after everything was paint stripped), but the actual head was a huge PITA, and I eventually abandoned the polishing when I got to the thumb lever...the pump head is a zinc/some other soft metal cast, and had quite a poof surface finish; there was a goodly amount of rubbing with steel wool/flexible abrasive blocks. Beware, though--one of my pumps had an anodized barrel, rather than a painted one, so...the paint stripper did nothing. If you decide to go that way, there is a thread somewhere on here about how to take the pump apart.

Amazing pump...might not top the looks department, but it's what I want when I have to inflate road side.

I suppose looks are subjective but the neutral satin-finish gray goes well with almost anything.

I found one at Goodwill for $2, missing the rubber piece where it grabs the valve stem. LBS had the parts for $2 more. Now, I just have to remember to take it, since it goes between 3 different bikes.

Here's my 62cm bike in its current, toured-on configuration. It has a 57cm top tube to give you an idea of HPX-4 fit.

I looked up a photo of your bike and I honestly don't see anything unusual about your pump peg. Lots of photos of these bikes with normal frame pumps. What exactly do you think is the problem?

Blackburn: Just as good as Zefal. But I always use a velcro strap too.
