It looks like a good idea.
I might be tempted if it wasn't so expensive.
It must make otherwise stif cranks seem flexy imo. Plus, 30t? Too low surely?
Not used one, but if I was to go back to 1x9 then I would def try it.
Offset the cost against either an Ngear jump stop and a bash + chainring
or pauls or mrp 1x9 + chainring and it doesnt seem quite so expensive.
Why on earth would it, or could it make a crank more flexy?
seems like a good idea, I am going to try the 28t version on my 29er. Will report back, but in teh meantime would love to ehar from anyone who has used one also!

Hold up I now see why it could make it flexy, I had not realized they all fit to the granny position, I retract my earlier statement, not sure it would be for me after all, I liked a 34t for 1x9 anyhow...
