|Compact pump for 120 PSI||Andante|
Apr 1, 2002 10:02 AM
|Had two flats this weekend (migrating rim strip on sun rims). Had a terrible time trying to get to 120 PSI, really could not get past 60 PSI, with both our compact pumps. Is there a compact pump that can mangage high pressures, or should I buy a Silica frame pump. Thanks!!!|

|You get 120psi with CO2????||retro|

|I gave up on CO2 because I couldn't get over about 85-90 psi in my 700x32 tires. If you decide to buy a frame pump, though, I like the Zefal hpX much better than Silca--easier to use, and they last forever (one of mine is at least 15 years old). Minipumps, at least every one I've tried, universally suck.|

|I don't carry a gauge with me but I know a tire filled with CO2 is just as firm to the touch as those I've pumped up with a floor pump to 120psi. I ride 700x23 - maybe there's a difference with the 700x32s as that's a lot more tire volume to fill.|

|The Innovations 16oz CO2 cartridge is rated at 130#. I had to use one two weeks ago and I think it took my 23mm tire to at least 120, I don't know about a 32mm tire though. Anyway, I quit carrying a pump 4 years ago.

|Advertised to 160psi. I use mine to pump in 20 psi and seat the tire then co2 to fill then top off with airstik if needed. The key is to block the pump head against something solid so it is not wriggling around and damaging the valve stem while pumping.|

|I pack 12g C02 plus a small Torelli mini pump. I practiced in my garage and it takes about 50 strokes to get up to 40psi then I finish off with c02 and that brings me up to 120psi. The good thing about this is when I got tired of messing around with frame pumps and switched to co2 back in July of last year, I've had a total of 1 flat on the road.
There must be a message in there somewhere.

|I can easily pump up a tire to 120 p.s.i. with the Blackburn Airstick.
That being said, I would think a frame pump would work even better. I don't have one because it won't fit on my oversized frame.
