Recently my Bell foot pump broke after 3 years of use. So I purchased a Topeak Mountain Morph Master Blaster. Can not figure out if its pumping any air into my tires because there is no gauge on it. So next I bough a Bell Windstorm floor pump. It works ok but I do not feel that the gauge on it is correct. To check if the air pressure is correct the next thing I want to get is a bike tire gauge and possibly another reliable pump. By the way I have a Shrader valve on my bike. Any suggestions would be most helpful as I am a novice with bikes.
