I mean no offense, but I will repeat what was said before. I think the solution lies in core strength and conditioning. A couple years ago, I had pain similar to what you're talking about. I didn't change anything about my bike fit. I did two things to try to fix the problem: (1) I intentionally varied my hand position / posture during rides. (I had been doing 60-minute drills in the drops.) and (2) I started a program of core/upper body conditioning.


Within a week or two, my pain ceased entirely.
