Sorry. I know it’s been on many times before, but the rule of thumb for chain length is around the largest cogs then add a link isn’t it? Does it go through the mech or not?

Thanks!

as seven said on my earlier thread;

“run it over large chainring and large sprocket – that length + 2 links

don’t run it through rear mech”

Or run it through the mech, stretch the mech tight and trim to size…..

Thanks guys.

Also, if its a suspension bike its not a bad idea measuring the chain with the suspension compressed ie, air out of the shock/spring removed, to take into account chain growth.
