Sorry this thread fell off my feed for a while so I didn't see it. I was using a rough number for a 25x700 tire. Obviously 38mm would result in higher gear inches. A 700c wheel with 38mm tires will run very close to a true 700mm (27.5") diameter.

This!

When I went looking for a new bike in 2018 I wanted a gear inch range of about 30 to 90 for a hybrid or comfort bike. I also wanted to keep increments between gears of 10 - 20% depending on the range with the smaller increments on the higher gears. Ideally with a single chainring. I like the cleaner look and lower maintenance. As it turned out the bike I wanted came with a triple chainring.

It doesn't matter to me whether I have 1, 2, or 3 chainrings if they meet the criteria above, I can make them all work. Each has advantages. Once you discover them, you will appreciate what each setup has to offer. I love my 28/38/48 triple crankset, And would probably be just as happy with a single chaining that meets my needs.
