Jeebus, this has gone right off the rails. Anyway, would it be ageist to infer that triple users are most often grey?

Personally -- as a proud grey person -- I find a triple (30-40-50) most useful for my pursuit -- marathon cycling in mountainous territory -- and agree with the poster above who pointed out it's the best way to keep spacing close over the widest range, e.g. 10 tooth jump, rather than 16 I explain my reasoning here.

And you may note on that page that the father of road racing himself was quite intolerant of the "fairer sex" and other lesser mortals:

“The [single] gear ratio was something we did not choose lightly, but once chosen, we did not change it .... Soon they will show us gearing that corresponds to every slope and to every state of mind. There will be gears for young girls, for brides, for family men, for skinny and fat people, for sluggish people and for drug addicts.” ~Henri Desgrange, L'Auto-Vélo, 1902
