Bike Gear Calculator : Bike Gears, Cycling Gear

It would be better if I could select 700x42 tire size. Without, it’s of limited value to me.

Need to update to allow for Shimano and SRAM 51t and 52t cassettes.

Having bikes with multiple setups, the app allows me to look at specs for a certain application without looking at the rig. I can update the app when I change bike gearing for most up-to-date info. It allows me to see most if not all parameters associated with the gearing; hence, I can choose the bike for the job quickly!

I really love this app and all the nifty functions that it offers. You can create custom charts of your multi-geared drivetrain that will give you an idea of the various ratios your bike has. I would recommend this to novice riders as it is very easy to illustrate how the desired gear ratio can be replicated without having to engage the “big-big” or “small-small” combo. A couple of suggestions to improve this app: 1. Add an extra digit after the decimal to the gear ratio displayed in the chart table 2. Add skid patch calculation on the home screen (bonus if it offers ambidextrous skidding). This would make the app attractive for fixie riders too

Nice and simple to use. Information available in single view. I love to challenge myself using app.👍

I wrote to the developer, asking that he add cassette cogs up to 50 teeth, and he did it within a week. Thanks!

Very happy with how this app works. I use it to calculate gear changes with advanced modern 1x drivetrains as well as how tire size effects gear range with all the tire width changes like wider modern bikes that are all road and gravel bikes.

I am using this app daily very good app to learn biking

Very good app to calculate Bike gear, i can even save results to compare multiple bikes

Very informative and useful
