[Closed] 10 speed chainrings on a 9 speed crank arms?

yup

I am guessing your 10 speed chainset has the nice composite middle ring?

Be aware that the ratios might be different as 10 speed are normally 24-32-42. Leave your 9 speed front mech where it is though as if you drop it down it will strike the middle ring as the 10 speed one is designed with a different path.

It will shift fine though.

Yes 10 speed has composite middle ring.
All other parts are 10 speed, just trying to loose the heavier crank body.

in that case it will all be fine 🙂

Thanks - looks like a budget arms with SLX type rings.
