I just realized I now qualify for this very exclusive forum (Nov 1945). My wife and I mostly ride our daVinci tandem doing 100K and 100mi organized rides 12+ times/year. The tandem has a wide gearing range, from 60-11 down to 24-32 and we use the entire range. Our short term goal is to do some of the medium-tough centuries around here (5000-6000' of climbing) and to further that end I've started a weight training program. No health issues so far thank goodness. I do have a single, a Giant OCR1 with a 50-39-30 triple and a 12-27 cassette, but I don't ride the single very much. Oh, and we took up bicycling about 2 years ago after a 20+ year layoff. Looking forward to the civil, mature discourse on this forum
