What kind of pump am I supposed to use on this bike?
 

Old Supergo Access hardtail MTB made from Columbus Cromor, with a top peg brazed behind the seat tube. Gotta be Shrader. Top and bottom mounts look like this:

The top mount is a standard frame pump peg. The bottom plate is a
kickstand plate rather than a pump mount. The non-drive chainstay
should have a ridge or spine upon which to mount the other end of the
pump. In your image it's hard to see if that's true, but I think so.

The pump would be a Silca or Zefal frame pump, probably Zefal for
Schrader valves.

Measure first.
From that era, a Mt Zefal or the Silca (model name?) MTB
pump probably.

I think it's almost certainly designed for a Zefal HP or HPX. At the end
of the pump head, those pumps have two sort of flat plastic pieces with
a concave curve cut out to fit up against a frame tube.
http://www.zefal.com/en/pumps/253-hpx-protection.html
They're about 19mm wide and 3mm thick.

One of those plastic bits is almost, but not quite, axial with the pump.
It looks to me like it would slip perfectly into that slot.

The Mt Zefal version is shorter and fatter with the same HPX
head.

Thanks a lot, boys. That Mt. Zefal "HPX Protection" piece looks like what I want. I'll see if the LBS has it.

If you can't find it locally ask Andrew.

Zefal HPX, most likely. Measure carefully because the HPX comes in 4 lengths. The non-nipple end fits over the chain stay by means of a concave bottom end to the pump.

Correct for the eternal HPX road pumps.
If I recall (always a crapshoot nowadays) the fat Mt Zefal
HP only came in one length.

The HPX was great. Too bad they ceased production. I bought several of them off of the Internet but they mostly were worn out. The French used a lot of natural rubber which rots.
