On this one, I was using a mini pump. No CO2 on this one. I remember last year someone having a problem with tire inflation and this was brought to the attention. For that, thankyou very much. I usually do a tire check before I leave the house on a ride.

Is there a difference between a road mini pump and a mtn mini pump? If so, where do you find a good mtn mini pump? Can you use CO2 on mtn tires? I currently have the blackburn road mini pump and like them.
