Since I check tire pressures before each ride, I find that cold pressures sometimes need to be increased, especially on the cold days (30 deg. and below). But I've yet to find a good hand tire pump. Any suggestions?
I also check my tire pressure before each ride and had problems on tours finding a gas station with a air pump. So, I went to a bicycle shop and found a small hand pump that fits inside of my motorcycle tool bag that I carry in my saddlebag. The pump cost about $20. and works fine.
