Thx... I remember that we are pretty close except my legs are a bit shorter in the inseam... and I seem to make up for it in the torso. I'm still thinking the RS would come pretty close to fitting me. I need just a wee bit steeper STA in the 74. I know you had to shorten your reach up by switching out the bars. That might be ok for me as is. The TT length of 51.5 is what the fitter suggested as well--same as the RS. I'm just thinking if I need my seat moved forward to get the knee over the spindle... then that puts my seat going up??? That part gets my brain confused. Maybe that's where he's thinking the 170 cranks could work. But, my legs just seem too short. Plus, I assume being a smaller 48cm bike it comes stock with 165s. Hmmm...
