I have a couple 110-74 Shimano triples and a couple 135-74 Campag triples (but i never adopted Brifters, use Bar end shifters..)

NB now that a cassettes have made 11 t top cogs , any big ring on a large wheel bikes over 46 is overgeared ..

Hence a lot of tour bikes built with new parts put an MTB 44 32 22 t triple on & places like VO get 46-30 doubles to sell ..


On my rides, the up shift from the 24 t to the 40t is done at the crest of a Hill.


The "market" is more the Product Managers for the various bike brand Importers specifying what goes on New Bikes at factories ,
Not individuals Buying components by the each for a specific Bike they are Building..

So its fashion choice , not a Function choice.. and truck load orders, of Pallets of cases is what matters to Manufacturers.
