Hello everyone.
I recently got myself a mountain bike from Canyon. It all works, got myself all the gear, pumps and all. And the pressure gage give me a reading of 10 PSI, which is odd because the tires are firm. 10 PSI should be nearly flat.
I have other pumps, including one that works for my car too, which I trust because I cross checked its values with my mechanic.
Here’s the odd thing. I got the bike out and plugged it to the car tire pressure device and it also gave me a reading of 10 PSI. I also have a Topeak Shuttle Gage, 10 PSI.
How is that possible? I can’t really believe all three readings come from faulty devices so I’m thinking I’m the one doing something especially stupid, or maybe a defect somewhere on the valve/tire but it’s brand new, so I think I’m the one to blame. Any ideas where I’ve been an idiot?
I did open the nut on the presta valve prior to taking measurements.
There’s no risk to using force? Maybe I just didn’t push hard enough because I was scared to put too much pressure on the presta and bend it. They look weak.
No risk. Road can go well over 100 psi in road stuff all the time.
