71 with historic back issues I have raised bars with tall quills and stems, gone to 28s , and with staying out of the drops has helped a lot. Riding 20+ miles every other day has worked out well as has staying under 40 miles. Only real issue is I can not bear to make changes to my Italians so they will have to go, I just can't put a Nitto Technomic on a Tommasini.
