So after all the great reviews the Topeak Mountain Morph has gotten, I decided to get one. Now, all my bikes have Presta valves.
When I reverse the insert in the chuck and try to use this pump, I start having a problem. The cavity of the chuck (which goes over and fixes onto the presta valve of the tube) seems to not be deep enough, and as a result, attaching the chuck to the valve means that air starts hissing out pretty much all the time - and quite rapidly, too.
This pretty much makes the pump useless.
Looking at the design, it doesnt appear to be defective or flawed. So am I defective/flawed and missing some pretty obvious step, or is anyone else also having this problem with filling prestas?
I like the idea of having a tube to attach to the tire, instead of the pump directly, and otherwise, I am very pleased with this pump. Anyone know if the Turbo Morph G also has this problem?
