Cadence/Speed Calculator(6 posts)

I recall someone posting a link to a website that allowed one to enter a gearing selection along with a cadence to compute a speed. I'm lazy and don't want to do the maths. I would like to use this to approximate the power output while on a Fluid2 Trainer. I have a mapping of speed to power, so I should be able to get an approximate power output. This is only to get a general idea.

This website was a very comprehensive calculator, it allowed one to select different coeff. of drag, wind speeds and directions, etc. It is complete overkill for this purpose, but I liked it nonetheless.

Thanks maybe? (nm)jtferraro

That wasn't the one I was thinking of, but that works well.

Thanks, I like this. It will be easy for me to extend to what I want and it shows me the conversions without thinking. I always wondered how to compute gear inches, I never bothered to figure it out, but now I know.

What I like about doing it this way is that you can see side by side different combinations, with resulting rpms and speeds, and you never even have to think. Lots of times I'll use it differently, for example by plugging in 41, 42, 46 for chainrings for the fixed gear, and then plugging in my max rpms and seeing what speeds I get. Makes it very simple.

Also, you can download it and save multible versions of it, and keep different gear combinations in each.
