Chain length?

[chris_of_1979]

Just bought an oversized rear sprocket and my chains now not long enough.

Am going to be running 14t front, and 42t rear - any suggestions for chain length guys?

I went 15/42 and added four links.

This works out the chain length , but i am sure someone has already done this mod & will be able to tell you how many links
