Patrick, I've run a 50-44-24 triple (non-ramped rings) with a 1990 Deore LX 3x FD without any issues, though it did prefer a crisp upshift. The original small chainring was a 28t, so I may - or may not - have been exceeding Shimano's spec for the FD.
I don't recall if you're using 'brifters' on your Roadeo, so I should mention that the bike was setup with friction shifting.
