For those interested in gear ratios and calculating the effect of a larger chainring or smaller cassette. This simplified calculator allows you to enter your own numbers. Just enter your chain ring sizes in the yellow cell aligned to your rear set up. More detailed gear ratio reference on the second tab. I run a 40t front and a 10/52 rear cassette on my gravel bike. Which is great for a hilly steep course or if your not a super strong climber but also can have some large steps between gears, circa 13 cadence as an example.The 44 front and 10/46 referenced is one of the new SRAM AXS set ups for reference.
