does this compressor pump air in a road tire to 100psi?

the specs states 90psi.
No, the specs say 90PSI at 2.6 Cubic Feet/minute. Max pressure is 150 psi.
Which, if running from a full 6 gallon tank at full pressure, should be able to fill a 700x28 tyre to 100psi in a handful of seconds.
My compressor has very very similar specs, 24 litre tank, 10 bar max pressure etc etc and does 3 or 4 road tyres to 90 psi before the compressor even kicks in.

It's also very useful for tubeless!

Shame. My old Super Pista from 15+ years ago is still going strong and performs and feels better than most new pumps I try.

It's pretty much a different company.

great to know. thx for mentioning! don't know anything about air compressors in that regard.
so 90psi is sustained moving 2.6 cu ft/min is what i'm understanding. filling a 700x25...shouldn't fill too fast since volume is lower than car tire i assume.

The cubic feet/minute is usually quoted for airtools. Impact driver, needle gun, spray gun, media blaster, which all need certain continuous pressures and/or volumeperminute to work properly. Like my impact driver needs 20PSI more than i can produce and about 0,25 cubic feet more. So it doesn't work properly.

Car tyres don't even empty the reservoir. 2 bar and 10 litres. Ish.
Bike tyres are more like 2/3rds of a litre, but 6 bar.
