Am I correct in thinking a 67/13 chain ring/sprocket combo with a road bike wheel travels nearly 3.5M?

Plug the values into [url= http://gear-calculator.com/ ]here[/url] though you can't go beyond a 64T chainring 😯
Cateye have a list of [url= https://www.cateye.com/data/resources/Tire_size_chart_ENG.pdf ]tyre diameters [/url]
If you have a 700 x 25c tyre then the development metre is:
I think the calc would be 67/13 x 2.105 = 10.8488 metres!

I meant in the linked calculator!
That's not a chainring, it's a frizbee!

...nearly 3.5m
The gear inches derives from the diameter of a penny-farthing front wheel (or some such arcane origin)
