I am really looking into the new t1550 gen 2. Love the colors and the huge amount of great reviews of the previous versoin. However, there is one thing that worries me: i have often heard that the t1550 gen 1 is very stiff, almost too stiff and therefore uncomfortable for longer rides. According to winspace, the rear triangle of the gen 2 is even 36% stiffer compared to the first genreation. Do you guys think the increased stiffness is is getting problematic riding gen 2?

How tall are you? I am 185cm, which is pretty mutch the upper limit of the 520 size. I am  currently considering whether i should go for the 520 with a longer stem, or play it safe and order the 550 with shorter stem. The smaller frame is lighter, has a more aggressive geometry and looks better to me.

thanks for your response. This is not the seatpost wedge. Its another one, much smaller compared to the seatpost wedge,
