The X9 reads to nearest psi. After over a year of use it still within 1 psi of the SKS gauges. One SKS reads 0.1 psi below the X9 at 40 and 60 psig. The other SKS is higher by 0.5 psi. Of course my gauges are not listed as NIST traceable. I got it based on Syd and Macky’s review. Yes I was influenced.
My only complaints are it is slower than my Bontrager track pump (10 psi low) and the screw on set up for presta has to be perfectly perpendicular to the valve stem when screwing on. Otherwise it will run but won’t fill. Odd it does not leak but just shows zero.
Buy a Presta to Schrader adapter and use the Schrader side of the X9. I believe I paid a dollar at my local Walmart, and it was the Slime brand.
Bicyclists should not complain about slowness, as we are the slowest vehicles with tires on the road. I consider filling the tires with air, once every two weeks, as part of my ride preparation (along with other things we prepare before the ride) and have learned not to complain about it.
