Well here is the deal I have a FSA road triple with 53-39-26 set up with a 12-34 cassette and it works excellent and without any glitch. Of course I am using XT shiftres and derraileurs too. My friend who I am doing this for wants a similar set up as mine but needs a 24 granny for the uphill. Yeah this sounds a bit much to do, but the reason why we have our bike set up like this is because it was my dream to have a all around bike that could be ridden quite fast on various conditions on the street and bike path, and then also at the same time have the capability to be ridden up on a fire road like a mountain bike. So I came up with this bike where I took a Giant OCR touring frame and placed a 29'er shock fork on it, a converted road triple, full XT components, a Rock Shox seatpost, and 700x32c WTB Cross wolf tires. And this bike rocks, whether riding on the road or fire roads this bike can do it all. So my friend like's this set up as much as I do, but hew needs just a little more grearing to make it up the hill. So I am just looking to see if anyone has ever done a 24 chainring before on a road triple, that's all.
