Bike Inseam ~32"
TT Crank Length: 172.5 mm
Road Crank Length: 172.5 mm
Like many/most, the major factor limiting my TT position is hip angle. If I go down as far as I'd like in the bars, there's almost a dead spot towards the top of my pedalling stroke. I'm working on my flexibility, but I doubt it'll make my on-the-hoods FTP (~300 watts) equal my TT FTP (~270 watts???)
I'm pretty happy with my road crank length; but if I had to choose, I'd pick 170. If I had to blindly pick a TT length, I'd go with 165 or 167.5. Anyone go down a size or two in crank length for their TT bike?
