Any recommendations? Should I get one that has a built-in pressure gauge? Should I get one that adapts CO2 cartridges or should be manual only?
Thank you for your help.
Most of the pumps that do both don’t have much capacity for pumping. They are a pretty poor minipump. I would say the same about just about any micropump. The Topeak Morphs aren’t a micropumps but they aren’t overly large either.
Carbon dioxide works but it does diffuse out quickly. A tire that is pressurized with
CO2 will probably be flat overnight without any leaks. The
CO2 is also a single shot kind of thing. The question to ask is how many cartridges you think you’ll need and how many you want to carry? A pump refills on every stroke.
As for carrying one, this is a Topeak Road Morph carried on the top tube. The pump comes with a mount that is meant to screw into a water bottle mount but it takes all of the mount. Zip ties, a bit of double backed adhesive, and the provided Velcro strap will keep it very securely in place.

You can find mounts that go under the water bottle cage that work as well. Both work. I have all of my pumps mounted under the water bottle cage now. The under the top tube one is a bit of a pain if you need to carry the bike for any reason.
