Will it be an utter pain? I don't change between chainrings much at the front - basically at the bottom and top of any significant climb. I do occasionally drop the chain using the standard ramped chairing and wonder if using an unramped one would stop this without making shifting too much of a pain
thoughts?
I was thinking along the same lines. You might have to ease off on the upper screw limiter so you can force it to change up. You wont be able to do the same for shifting down but that shouldn't be too much of a problem.
TJ,
You know the older 7-speed sets did not have ramps and pins, yet we could still shift by backing off the pressure a little.
So, it will still work, just not under a heavy load.
As for whether it will prevent dropping the chain, I think it will make no significant difference at all. How can it?
By 'dropping the chain' I assume you mean it bounces off on a descent.
You need a chain device and the correct chain length, or maybe a new Shimano XTR Shadow+ mech. Or a new Saint/Zee if a short cage is OK (single ring only from STW Sea Otter coverage).

Did it for a while a few years back (24/38 Blackspire unramped rings), and didn't seem to be a problem.
I mainly stayed in the 38, with only very occasional trips onto the 24, but as long as I wasn't trying to shift whilst pedalling hard still (this is what the pins and the ramps help with mainly) then it worked ok.
What PaulD said.
.
Im running a 2 x 9 setup with unramped middleburn rings and it works fine for me. I also dont change much up front so it wasnt worth going for ramped rings. I have a 26/36 so not such a big jump. I just use an xt front mech with no other chain device and not yet dropped the chain.
Sure I've got a Saint 38T in the garage you could try, if that's any use to you? I had pretty poor results with an unramped E13 ring on a double, but then it's a pretty well worn chainring.
38 is a bit big I think northwind - got a 22 granny on it. ta
