Anyone ever tried using a narrow wide chainring in a double config?

Hi PL forum,

I know narrow wide chainrings are designed for 1x applications, but wondering if anyone has made them work with front shifting.

I am contemplating a wide/low double setup in front with shimano r7000 11sp group. I have a wolftooth 44t narrow wide ring i wanna use as the "big" chainring.

I anticipate the shifting performance will kinda suck but might technically work? I am using a square taper crank so i can mess with spindle width if needed to give the FD a little extra power to throw the chain over to the small ring.

Has anyone done something like this before? Can you tell me if it's gonna fail catastrophically or work so poorly that i'll be miserable?

Any advice/criticism/ridicule is welcome.

b,
adam

I don't think you're going to have very much luck getting a derailleur to shift out of the narrow/wide ring - they're designed not to let go of the chain - but I'd be curious to see how it works.

What about something like this instead?

No. the whole idea of the narrow wide is that the narrow tooth always meshed with the narrow plates of the chain and so on with the wide. this works because you never move the chain off that ring. you would have at best a 50/50/90 shot of the wide tooth trying to push into the narrow plate sections.

wont work.

Also the fact that the chain will only properly mesh with every other link would likely be an issue. Maybe in theory if both rings were NW, there could be ramping that feeds properly from N>N and W>W teeth, but I reckon that doesn't currently exist.

Just to illustrate:





Won’t work.
