graphical gear calculator
I've created a graphical gear calculator for those who love to play around with different gear combinations:

should be self explanatory. Have fun!

The field where you specify wheel size in mm (needed in case none of the options in the popup menu apply) is expecting a wheel circumference, not wheel diameter. You might want to make that clear.

Adding larger sizes of 700c tires (35, 37, 40mm) would be handy for those of us who ride hybrids. Also smaller wheel sizes (16, 20, 24 inch) for kids' and folding bikes. Very intuitive GUI, nice work, thanks.

It's great that the page allows a user to cut and paste a URL with settings specific to the user's bike. For example, this is my favorite commuter (a Surly LHT with 26inch x 2.0 tires) with a fairly typical commuter drive-train.

Thanks for making this calculator public.

Thanks a lot for the feedback!
The larger tyre 32...47x622 sizes are in the list, I just added the older 28x... notation instead of the french "700..." which was not common for commuter bikes (at least over here).
Regarding smaller wheels, I simply don't know which 16" and 20" sizes are the most important ones out of the long list.
If you have some recommendations for the most typical small wheel sizes (e.g. Brompton, Moulton,...) I'll include them.
That the circumference is required is stated in the tooltip now.
BTW: My everyday bike has this combination:

Can we get cadence ranges with bars showing the speed range instead of the single number with triangles, like on Mike Sherman's calculator
https://home.earthlink.net/~mike.sherman/shift.html
That makes it easier to visualize where the gaps are.

I changed the graphics to a logarithmic scale so that the gear steps are evenly displayed. Is this better?

Nice calculator!
For the vintage folks, it would be good to see selection(s) for 27 inch tires included.

Very nice indeed. Skinnier 559 sizes would be helpful. I'm riding on 559-32/26x1.25 currently.

Thanks. It's nice knowing there are such smart guys here. I would never be able to put anything like that together. Never in a million years. Thank you!

this is fantastic.
for 20" the most common sizes used would be 406x28 (1.125), 406x38 (1.5), 406x46 (1.75), 406x50 (2.0) and 451x28 (1-1/8)
a manual circumference input would be good.

I'll add some more tyre sizes soon. Entering any size manually is already possible. Just enter it in the input field next to the size selection an click OK.
