I've recently found a Diamondback Serios AF secondhand (size 56 frame), but I've never been fitted for a TT/Triathlon bike. I'm 6' 2" with about a 34.5" inseam. Based on some of the data I've seen in this forum I'd guess that my pad stack and reach are somewhere in the ballpark of 620 and 500 respectively. I'm not entirely sure though. I'm a young guy who's pretty flexible so there's probably more leeway there than I understand. Looking at the stack and reach database, it looks like the base stack and reach for the frame is 552 and 421. Does anyone have any input as to whether these numbers make sense as far as sizing or is it too small of a frame? Thanks!
