I am 6,6" and the Renthal FATBAR Carmical HIGH is 4.25 High.
The Pastrana bars are Just a bit higher at 4.5 but are 1.5 inches narrower.
I AM REALLY HAPPY WITH THE RENTHAL CARMICAL HIGH BEND!!!
The RC's are 802mm (W), 119mm (H), 54mm (sweep), vs the Pastrana
775mm (W), 121mm (H) and 55mm (sweep)
As you can see these bars are very simular in size, the "major" difference is the Pastrana bars are about 1" narrower (25.4mm=1" I believe)
Some say the Pastranas are better for tighter stuff because they are "narrower", but they are only about a 1/2 inch narrower on each side, and I do not really feel any difference from the normal 800mm or so width of most bars out there.
