I'm 64. I ride an '84 Peugeot I bought new. Some where around 25 years ago I put a 52-42-32 triple on the front. Rear is 13-28. I was having trouble on climbs. The front triple is now 50-42-26, same rear gearing. With the 26-28 combo, climbing is no longer an issue.I spin like Hell to go 7 mph but it works for ME.
Just my $.02 worth.
