Anyone run these together?

Use a C guide with a normal mech and its great, but not sure how the chain tensioning on a shadow+ would effect a C guide

Not sure you’ll need the C guide.

That’s what I thought, but on my current set up it really pulls the chain tight up and out of the way between the wheel and crank space.

Bionicon doesn’t recommend you using the C-guide with the clutch engaged – you risk ripping the guide off. I’m sure there’s those who’ve done it anyway without issues though.

Seems ok for me so far without too much tension on the C-guide, I.e. using it as a lower chain guide rather than a tensioner (the clutch does that).

Norco Sight 2 SE has this setup

i have the Sight 1, and have previously used the C guide on other bikes with clutch mechs. it is not required at all. the c guide is a terrible thing, the chain saws through it regularly and increases drivetrain friction so much.
ditch it and either use a proper chainguide or go with the clutch mech on its own, they are awesome.
