Bought a Pesta compatible tire inflator fitting to use with my little air compressor in my garage/diy bike shop. Upgraded the pressure gauge to a more accurate digital version. This set up is ok but I’m hoping someone in the forum can suggest a better set up.
@B0bb0 M A Presta-compatible fitting on a small compressor with a digital gauge is honestly a solid foundation. You're already ahead of most people who are still squinting at an analogue gauge and hoping for the best. But since you're clearly the engineering type, there are a few directions you could go depending on what's bugging you about the current setup.
The main weakness of a compressor and separate gauge is the workflow: inflate, disconnect, check, reconnect, bleed a bit, check again. If that back-and-forth is what you're trying to eliminate, the Voxom EPu2 is worth a look. It's a battery-powered mini compressor with a digital display showing both target and current pressure in bar or PSI. Forum members have found it tracks within about 1 PSI of a calibrated gauge, which is more than good enough. It won't auto-deflate if you overshoot though, so you're still bleeding manually if you go past your target.
The other approach, and this is arguably the more elegant one for someone who likes data, is to use a shock pump with a bleed button for final pressure setting. You inflate slightly above target with your compressor, then use the shock pump's bleed valve to bring it down precisely. The PSI reading flashes as you bleed, so you can nail your exact number. It sounds fiddly but it's actually quicker than the inflate-disconnect-check dance once you get the rhythm.
For the "set and forget" crowd, there are also in-tyre pressure monitors now. TyreWiz sensors connect to Garmin devices and let you monitor pressure during rides, which is useful if you're trying to optimise rather than just maintain. They're around $200 for a pair, mind. Tubolito also makes tubes with built-in NFC pressure sensors if you're running tubes, though I suspect you're tubeless on that Levo.
Given you're out in Whistler, where trail conditions swing from moon dust to biblical mud depending on the season, getting your pressures dialled is worth the investment. For your Levo, a good starting point is somewhere in the 20-25 PSI range depending on your weight and tyre width, with the front a couple of PSI lower than the rear. The Wolftooth Tyre Pressure Calculator is a reasonable starting reference, though it tends to run slightly high and doesn't account for inserts if you're running them.
I've also got community data on specific pressure setups from other Levo riders at various weights if you want to compare notes.
