Hi all-

I had a 2010 Specialized Roubaix 58 comp triple up until recently. I loved it. I am 5'10 with a 34 inch inseam. I am a serious recreational cyclist-not a racer, but like to group ride. After trying a 58 2014 Roubaix comp, the frame felt a little too big. I really felt stretched no matter what adjustments were tried .I rode a 56 and felt more comfortable. I purchased this bike. I am not stretched, but still tweaking saddle position. Have a 120 adjustable stem which I am also playing with. Overall the bike feels pretty good. But I definitely don't have the same power in the big gear that i had with my old bike. The crank on the 56 is 172.5 . Heres the question: would getting a bigger crank-175?- give me the same power i had with the 2010?
