Bikes like the Shiv and Slice are 'tall and narrow' which means more headtube and shorter toptube. Bikes like the P5 and P2 are somewhere in the middle.

But intentionally going upright on a TT bike is just silly, you're basically negating any benefit the geometry and design gives. Just stick with the road bike.

Scott Plasma, BH GC Aero, Blue Triad, Speed Concept, and some of the Felts are all Tall/Narrow bikes as well.
