HOLY OLD POST BATMAN !!
I had two broken ribs last summer and 2 more in the fall. I had to stop riding my CF bike, I found it too uncomfortable this spring and sold it. I have an old steel bike that I found comfy right away and has only been better as I dialed in the fit. This year I have been putting anywhere between 150 and 300 km a week and have never felt stronger. I do not have the same pace that I used to but I sure am putting on more miles and feel fresher.
