There are 3 nearly identical gear ratios (0.6%, 1.1%, and 2.1% diff) and 3 darn close gear ratios (2.8%, 2.9%, and 3.3% diff). So, unless you want to do some painful double shifting across multiple gears to access them, you really have 16 useable gears in the best case scenario.
From highest to lowest, they are:
48/10, 48/11, 48/12, 48/13, 48/14, 48/15, 48/17, 35/13, 35/14, 35/15, 35/17, 35/19, 35/21, 35/24, 35/28, 35/33
Gear ratios don't change with tire width. If two gear ratios are the same with 35c tires, they're the same with 42c tires.
Yeah, of course 24 gears, as there is no 2x13 drivetrain out yet. And yes,
all SRAM Force AXS drivetrain are 12spd. Plug in those 48/35 crankset and 10-33 12spd cassette numbers into the Sheldon Brown or BerkshireSports gear ratio calculator you prefer and you’ll find none of the gear combos actually move the bike the same distance per revolution (i.e. in terms of inches of development with either 35c or 42c rubber) they are all distinct, and as I’ve been saying, that’s what’s important for riders seeking to optimize their output.
