The pump I borrowed was my friend's Topeak Road Morph. It's fairly light and small. It also has a guage. Of all of the frame, compact, mini, or convertable pumps that I have tried (lots), this was by far the easiest to use. Pumps to high pressure easily.
Yeah I have one of those, it's great - weighs a ton though.
This is WW!!! Great pump for touring/carrying abroad to keep at base. Gets to 115 psi no probs which is fine by me. But don't ever put it on the bike!!!
The Carbone mini pump is superb IMO. I have used a few others such as Toppeak Master Blaster and Blackburn Airstick but the Carbone outperforms them and weighs 1/2 as much if that. The trick is to use the thumb/finger indents to push hard up into the rim with the valve at 12 o'clock. Ok, this might be a bit hard on the valve, but i have reached 100psi many times and for such a light pump that isn't bad.
This is the preface that was cut from the quote:
I carry CO2, but a couple of guys I ride with carry Topeak Road Morph pumps. On a recent ride, I had a valve that wouldn't seal properly. Removed the valve, checked for any debris, replaced the valve, and filled the tire using a CO2 cartridge. Bad plan! The cold CO2 made the seal problem worse and the tire deflated quickly.
The solution was to remove the valve, coat it with a little sealant that I carry, replace the valve, and inflate the tire up with a pump. Probem solved, and no problem since.
I carry co2. WW and works for me almost all of the time. I was glad to have had the opportunity to borrow the Road Morph on this rare occasion when co2 was a problem.
