Is there a website where I can see the difference of gear ratios? ie 52/36 with 11-30 and 50/34 with 11/32?

Am I the only one who just made his own gear chart using Excel? Mine tells speed too at whatever RPM I enter. As well as gear inches. I'm always comparing different cassette combinations with different chainring combinations to arrive at the perfect gearing!

No. I did that before the internet was a thing as well.

Well. I wrote a program in basic to work it all out. Then did it again in lotus 123.
Really is no point now, as gear-calculator is easy to use and gives graphical inputs and outputs.

Gives speed at rpm as well.
