Yes, so true Don. My Stevenson Custom was built with all Campagnolo Record 8sp gruppo but with the Comp Triple cranks and triple bottom bracket, this lasted until about 5 years ago when I found I could not longer find essentials parts at any price! So I upgraded to 10 speed Record, but have watched the same thing begin to happen again. This time I began early stock piling of enough of the consumables to last me into the early 100s. Why 100s, but of course, my current hero Mr. Marchand of France who retired form setting Hour Records for his age group at 106. Now that's what I call a goal to aspire to.
Wife and I plan for the mixed tandem 100 Hour Record, gotta keep my stoker engaged, lol.
