That or the more common 42 - 24 was a large reason why many

I wonder if during tthe 1970s and 1980s bike nooms if a gear
of even 34 - 24 or 34 - 30 would have kept more would be bicyclists
in the sport? That in turn would h ave made for safer riding due
to far more bicyclists on the road.
I've read many times that hills are one of the big items that dissuade
people from cycling. In general, flat cities tend to have more cyclists
than hilly ones (although of course we'll hear about exceptions).
And I remember letting one friend of mine try my bike with its (then)
newly installed triple crank. His remark: "Wow! It doesn't matter if
there's a hill or not!" And he soon bought a bike with a triple.
But as with most technical aspects of bicycling, people don't understand
what's important, and few salesmen explain it. 12 speeds were always
portrayed as better than 10, 14 better than 12, etc., but few people
bothered to ask about how low the gears were. In fact, a lot of the
gear count was wasted (for non-competitors) on gears above 100 gear
inches. Much better to give them lower gears, even if seldom used.

Yes, the high gear of just over 100 gear inches with the standard 52 x 14 combination on jmany road bikes was too high for a lot of people. Now theyre selling bicycles with a 53 chain ring and 12 or 11 teeth cogs as standard. In my opinion it'd be a lot better to have lower gears on the standard bikes for the general public and the higher gears for the more elite riders. It seems to me that over gearing many bicycles results in bicycles tthat a lot of people can never hope to use the high gears of - ever. That turns people off bicycling.
Far too many times i have people ask me where i'm going to ride. When i tell them and they ask if there are any hills tthey're usually put off because their bikes just don't have the low gears they need.
Changing from a 52 - 42 double to a 30 - 40 -50 triple is very expensive for a lot of people as it means getting a new crankset, bottom bracket (if it's a sealed unit) chain and many times a new rear mech. If they're really unlucky, they need a new fron mech too.I really believe that a lot of people are sold bicycles that are totally unsuited to their actual needs. Cyclo-cross bicycles with wided clearances and barzeons for racks etcetera are very popular here in town due to those bicycles being so versatile.
