Pump gauge problem(6 posts)

Pump gauge problemJoshua
May 5, 2002 4:10 PM
This could probably be the dumbest question of the year but I have to ask. I got a pyramid pro floor pump, and I tried to pump up my roadbike tires. first after abot 6-8 strokes It got real difficult to pump and the guage only showed between 25-30 psi. There is more than that in the tire though. Now the gauge on this p.o.s is stuck at 25 psi. Do these pumps have a pressure relief valve for the guage? I looked and I don't see anything that resemles one any where. Once you guys are done laughing at this post all help is appreciated. Thanks

Very simple: busted tire pump gauge. I've gone through a ton of these pumps in my quest for a reliable, accurate gauge. Finally, I think I found the answer with the SKI Rennkompressor, not cheap at 45 bucks, but hasn't broken in a year (which is saying a lot). Pumps to 200 psi.

I had a pup guage that was off too. It would read about 20-30 PSI too low. I ened up blowing out a couple of tires. I bought a new pump after that. I keep the old one in my car. It can come in handy before a group ride.

If there is a rebuild kit for the head of the pump, you may want to try to repair it. The guages are not reliable on many pumps. You may want to get a stand alone guage. There are a few good ones out there for $10 to $20. I use a Topeak digital.
Those gauges are notoriously bad...cory

Not just THAT pump--gauges are often off by 5-10-15 pounds, just like the car gauges on the ends of gas station hoses. It's a good idea to have a separate gauge, or at least know how far yours is off and check it occasionally against an accurate gauge. Since the day it was new, my Zefal has read 56 psi at an actual 50 and 120 at an actual 100 psi.

You need a new gauge, check with CC or Excel and see what they got.

Incidentally, my guess is that you weren't getting air into the tire and maxed out the gauge. Did the gauge ever climb up to a hundred? Some times the presta valve won't unseat by simply unscrewing the top. you have to press it in first or just a good hard blast on the pump handle to get the thing going.

Or possibly it was just what you said, "a p.o.s."
There was air going into the tireJoshua

The tire was flat to begin with and I did get it full of air. The guage just stopped at 25 psi though.

I took it in traded it for a topeak joe blow sport seems to work just fine. I may buy a stand alone gauge later though.
