Like you, I am 67. I haven't stopped riding, but I have observed my body changing. What was all day comfortable when I was 62 isn't now and I have to make real changes to bike fit. When I get off the bike for any time at all, I have to raise the bars. The reach I could do through my 50s is no longer. Shoes and cleats need far more attention. I've gone to laced shoes because they are so much more forgiving and dialing in tightness can be done with an accuracy not possible with 3 straps. Handlebar rotation and lever position are now critical form me, both for while riding and to be pain free after.
I would never accept that if everything is uncomfortable, all is good. Maybe a good time for a bike fit? (Of course, safety first.)
