11 speed chain on 10 speed chainrings

I read that this works, which appeals to my weight-weenieism,

as the (KMC X11SL) is 20g lighter.

After semi-diligent chain cleaning/lubing & satisfactory life on the old chain

I put the 11 speed on my 10 speed bike (S-works 34-48 rings)

and it just spun between the rings, never dropping to the small ring.



So if you're thinking about doing this, don't bother.

It's the spacing between rings rather than the rings themselves.

Maybe you need to back off the "L" screw 1/4 turn.

Adjusting might fix it. Possibly the narrower 11 speed chain might not shift as quick. So a delay in shifting will quickly overtake the big advantage you got by saving 20 grams.

Maybe leaving an ounce of water out of the water bottles could offset the problem for those forced to go back to a 10 spd chain.

I use a 10 speed chain on a 1980s "5 speed" crankset. Works pretty well.
The miniscule difference between 10 & 11 shouldn't cause a problem.

I saved 17g for $15 changing my water bottle cage bolts to aluminum, and my stem bolts to Ti. I'd rather try finding somewhere else to save weight and keep the better performing chain.
