Being a sidewalk rider, I primarily bought this to top off my Airzound GTFOOMW people mover and for that task it works.
As far as pumping up a low 26x2.0 low tire = I tried and it was an epic fail.
Unlike Bart, I don't have the 'superman' strength needed to to "get 'er done".
@ 66 years young, I barely have enough 'umph' to screw in the CO2 cart.
However, you younger bucks and (stronger) buckettes with those skinny-minny 700 tires, if you follow Bikeman's video about this item - You shouldn't have an issue.
I would like to see Serfas update this pump with a CO2 lock-out/safety bar to prevent an accidental triggering of the devise while it bounces around in my tool bag. Teas, I know... It has a frame mount, but where I live & shop there is beau coup foot traffic and much of that foot traffic suffers from 'sticky finger syndrome'. A slide down swing out pivoting T handle would be nice for the pump feature.
At the end of the day, a great item to have!

Pump works easily as described, well made and nice weight for saddle bag. The addition of CO2 is my reason for purchase, I run high pressure tires and fine tuning psi is wonderful.

I would like to say that the Serfas Frame Pump with C02 Inflator plus Gauge AP-C1 is an amazing bike pump that I would suggest anyone looking for portability, convenience of having CO2 cartridge for emergency air plus doubling up as a normal pump cannot go wrong on having one of these strapped to their bike. I would recommend this product without a shadow of a doubt.
