okay, so I've got a 15 year old zefal husky floor pump and almost thirty years of racing experience. I've thought I've had reasonably calibrated fingers and can gauge tire pressure pretty well.
but for $5 at a bike swap, I bought a digital tire pressure gauge made by Slime. I took it home, and tested all my wheels. Mountain bike tires - 18 psi. 'Cross clinchers - 24 psi. Road tires, 85 psi. Hmm. Seems pretty low I thought. Must be a lemon. So I ignored the gauge and continued believing my zefal pump.
Then the other day at the LBS, I decided to buy another gauge (same model) to see how far off the original (bad) gauge was. Funny thing, it's exactly the same.
So now I'm stumped. Either my buddy zefal and I are way off, or slime's gauges are consistently wrong. Not that it really matters - I will ride the pressure I ride anyway, but it's interesting to compare to pressures of others, of pros, etc.
So, anyone use a separate gauge? Any experience with these cheapo digital gauges? Anyone use gauges religiously, as opposed to the pinch technique?
