Crank-set going from 50-52 - add a link to chain?

Postby Pollys Bott » Tue Jan 22, 2013 21:32 pm

Like the title says - having bought an Ultegra crank for the 'posh' bike the old Octalink 105 crank is going down onto the commuter / winter bike replacing a Tiagra. 105 big ring is a 52, Tiagra is a 50: I'm not going to need to lengthen the chain by one link for that am I?

Try it out and see. The change you are making will need an etra 1/2 link. Since you can't add that I think you will be fine without adding a link. Also adding a link to a 9 speed chain is not recomended unless you are going to use two master links. If your chain is not too short at the moment you will probably be fine.

Thanks for the reply - moved it straight over and it appears to be OK as is.

Doesn't that assume an unlikely precision in chain length? Chances are, the existing chain might be a touch too long or too short for the 50 so that would determine if an extra link was ideally needed.
