I have the Roadmorph-g, mountianmorph-g, and the Parktool frame pump http://www.parktool.com/product/dial...ame-pump-pmp-5. Of the three I like the mountian morph best, it just seems to get 32 and 35 tires full faster. The gauges on both of the morphs are a little sticky and give only an aproximate pressure. Of course the Parktool has no gauge, but it does adjust to fit different frame sizes or locations.
