After riding for about 300km, I'm looking at adjusting some parts to fit me.
First adjustment: Because I feel that I'm stretching a little too forward, causing my back to ache, I've decided I would decrease my stem from 110 to 90.
Second adjustment: Because I feel that the saddle is too small for me, causing the sensitive area to compress, I've decided to change my seat to swork power (OEM).
Right now I'm looking at my leg reach to the pedals. Currently I feel that I have to stretch a bit more than I feel comfortable to, while pedaling, so I'm considering if I should shorten my seat post or change my crank length from 172.5 to 165. HOWEVER my seat post is integrated to the frame, I feel like I shouldn't cut it (plus its risky as it is carbon).
165 cranks are rare: I only found Dura-Ace 7950 that would cost me $275, but it would be a upgrade from the current Ultegra. Also my friend is saying that changing my Ultegra BB to a Dura Ace BB would make my ride much smoother.
Please advise me if all these changes I'm doing are advisable. Also crank change vs seat tube cutting!!
