My experience agrees with Garth's. Wait a minute: That can't be right! Garth's experiences are way too far out and exuberant for me!
Let me rephrase: Garth's experience shifting an older crank with a newer, narrower chain, matches mine. I use a Ritchy Logic crank, 8 speed,* with an 11 speed chain on a 10 sp cassette (a slightly narrow chain seems to improve or ease rear shifting) and I've never had any problem with the chain falling between the rings. * Now the chainring spacers for the granny come from who-knows-where, so they may not be 8 speed ones; they may be 9 speed ones, but never 10 speed ones. Or, they may be 7 speed ones. At any rate, friction shifted, I've never even had to think about the mismatch; it just works fine. (Also, bike has 5-speed friction bar end shifters pulling 8 speed rear derailleur over 10 cogs with 11 sp chain: wonderful shifting.)
