Last week I put the triple chainrings back on my cranks as I've converted the bike back to geared from SS.
It looked like this (not my crank);
and all appeared well.
I very rarely use the granny ring and on the two occasions I ended up selecting it (because I thought I was in the big ring at the front not the middle) yesterday the chain fell between the middle and granny rings and jammed.
I'm confused. The middle looks like it's in the right place (pins facing inwards), the granny looks right - writing inwards, bolts in the recesses in the rings.
So what have I done wrong?
