I still recommend this pump.

Just FYI ... You can still mount the original under a bottle cage if you use the zip ties.

To answer the original question ..

1. Road morph is longer and thinner for low volume/high pressure tires
2. Mt Morph is fatter for high volume tires
3. Turbo morph is same as Mt Morph, but it has a top mounted dial gauge.

My 40 something eyes are not what they used to be. I sure would love to have that new turbo morph, but my road model is still chugging along. Any of these should serve you well.
