Chain length on a 1x with OSPW

Triathlon Forum

How do you measure your chain length on a 1x with a OSPW pulley?

Can’t follow shimano’s guide line 1 on 1 because that doesn’t take in consideration the larger pulley wheels.
Can’t follow ceramicspeed guide because there is no inner chainring on the front.

I read on some pages 1x’s need 2 extra links, but that is with normal pulley so add maybe 2 more?

Is there even a guide on this:-).

Yes there is. It’s just the same as the outer chainring. And as the middle chainring, really.

How do you measure your chain length on a 1x with a OSPW pulley?I can’t quite believe you as a “Tri Pro” are asking this (and given the overwhelming response I’m not alone). The OSPW makes no difference as the chain is close to straight in large pointing about 5 o’clock and the pulley wheel radius makes minimal difference.

Well, I just wanted to be sure as we didn’t have to do a lot with 1X’s here and it is actually slightly different as what I thought. I was off 2 links :-).
I just like to double check

Chain on front chainring, rear largest cog with chain already through the derailleur and when that is the OSPW part should be pointing at 4 o’clock direction.
