I haven’t had very good luck with small/mini/micro pumps.  I’ve had some that worked marginally, and the rest have been literally useless.  I also have some CO2 cartridges and valve, which work, but are wasteful, expensive, and rattle around in my jersey pockets.

Below is a Park Tool PMP-5, an adjustable frame pump that fits a range of frame sizes with and without a frame pump mounting pegs.  In addition to freeing-up my jersey pockets, this pump actually works.  The only change I made was to cover the silver and blue aluminum barrel in black vinyl– the silver and blue didn’t look so great with the ’90s Trek ‘Ice Violet’.

Overall, this is an inexpensive pump that fits a lot of different frames and can inflate a road tire to a reasonable pressure in a reasonable amount of time. This may not sound like much, but it’s more than can be said for most pumps.

The PMP-5 fits securely on my 52cm steel Gunnar Crosshairs, without pump mounting peg, and with a very short head tube:

And, here it is on the 56cm lugged carbon Trek 2120, with pump mounting peg, which previously used a Zefal HPX-4 :

Yes, another bike.  This is an Ice Violet 1994 Trek 2120, the carbon and aluminum touring bike with a strange mix of 105 (road) and Deore LX (mountain) components.  According to Trek, mixing road and MTB component groups is a dream come true:

2120 ABT Carbon Performance Touring

If you think performance touring is a contradiction in terms, think again.  This bike can circumnavigate the globe as easily and comfortably as others circumnavigate the block.  That’s because our lightweight bonded carbon frame is far and away the best ride going.  You asked.  We answered.  This is your dream come true.

More in the full 1994 Trek Catalog.

This 2120 originally came with a triple crank, which explains the rear derailleur, and equally odd bar-cons (bar end shifters), which are actually unexplainable.  I’m not particularly fond of bar-cons or triple cranks, so both of these had to go.  The original wheels were in sad shape with broken spokes and some very suspect hard-anodized rims.  I found a pair of Shimano RS20 wheels for about the same price as my tires, so that was an easy fix.  The remainder of the up/downgrades include a 9-speed SRAM PG970 cassette (12-26), 105 Octalink crank (50/39), 105 8-speed down tube shifters, a Flite Ti saddle and some Vittoria Open Corsa Evo CX 25mm tires.

Trek’s published weight for the 2120 with the orignal configuration is 10.061kg (22.18 lbs).  My scale isn’t as precise as theirs, but my 8.9kg (19.6 lbs) still wins.

You may have noticed that I have 8-speed shifters and a 9-speed casette.  The drivetrain actually works pretty well in indexed mode, though the friction setting on the shifters is a bit smoother.  At some point I’ll swap the 9-speed cassette for an 8-speed, but there is no rush.

In the mean time, I’m looking forward to riding this on the road and getting the Gunnar back to the dirt.
