Gear differences question.

Postby elderone » Thu Oct 10, 2013 20:47 pm

What is a 39/26 gear the same as on a compact 30/12.Is there a way to work these things out or a site that already has.
cheers

You can just use division, so 39/26=1.5 then 34/1.5=22.666666 so the closest equivalent gear to 39/26 would be 34/23

Edit: assumes wheel sizes are the same...

Try this site. I really like the way you can move things around and compare them.
