I'm not a fan of that frame design. I have one that is 63cm, and I didn't find it to be as stiff as the initial design, even though Bicycling Magazine tested that design (in 56cm) on their Tarantula and pronounced them the stiffest frame available.I have not seen any comparison to the earlier design, nor have I seen 63cm test results.
Maybe I've been too critical?
