I carry a mini pump to get me out of a pinch, often I am 50 km from the nearest bike shop. The Topeak Mini pump, more so has got me out of bad spots a number of times. Topeak Mini

Overall Topeak products have been kind to me.

The Joe Blow Sprint Floor pump has worked well for me Joe Blow Spring Pump The gauge appears to be accurate, once I find a gauge to test I’ll post the results.

Best co2 inflater found so far is made by Silca, ordered from bike tires direct. “Simply the best”
