Id like to add about APEX,
that the 34x32 gear is amazing!! i had the oportunity of using it on the steepest hills ive ever done, and it was the only way to conquer such hills! i was hyperventilating, never have i gone up such nasty hills!! when i went down the hills i used the 50x11 and the bike had such strong torque down the hills! i got scared and used the brakes...so im yet to discover top speed on my bike....
The shifting is pretty good, cant really compare much, but it does what it does. The shifter paddle feels very solid if thats of any interest to you guys. Im pretty new to modern groups but my impression is very very very positive...it does intimidate a lot better than the tiagra and 105.
i made a thread about apex on specialized elite 2011:
