There were two frames I was looking at: http://www.rideblue.com/bikearchive.php?state=t12

and the Cyfac Le Mythique (Seat Tube 49cm c-c 54cm c-t;Top Tube 51cm c-c;Down Tube 58cm c-c;Chain; Stays 36cm c-c; Seat Stays 47.5cm c-c; Head Tube 15.5cm e-e).

I am pretty vertically challenged - 5'4.5" (roughly) w/ an inseam of about 26". I'd consider myself pretty flexible... although I don't know how I'd indicate this... I can put 3/4 of my hands flat on the floor when bending forwards

I know I could just get a "real" road bike but these frames are at pretty reasonable prices on ebay (compared to other framesets and frames I've seen both online and in my LBS).

I've heard that tri/TT bikes are less 'agile', but how noticeable is this, and is this due to use of aero bars (which, if I purchase a frame, I wouldn't use anyway)? I normally ride an Azonic Evolution set up for "aggressive XC"
