I guess I always thought I was a 545tt person because literally everything out there is "under 5' 9", get a 54" The calc is made to use a 100mm stem right? at what degree?
Right now i have a 550tt with a 73ht/74.5st 129mm headtube length with a 100mm +10 stem slammed to the 10mm dustcap with Nitto BB123 SSB bars (107mm reach, 170mm drop).
It feels pretty comfortable, things I am hoping to accomplish with the new bike are more aggressive racing feel, a better made frame (it's a purefix), and a bit more stability at high speed.
On a side note, how accurate do you feel the calc is concerning road bikes?
Here's me spinning and sprinting over the summer.
