Yep. Even if the front derailleur works OK in the bike stand with a larger than optimal gap to a smaller chain ring, it's a matter of time before the chain will get dropped, at least damaging the frame/paint or worse (injury). Get one of these, I have one, works well (Shimano D/A 7400 front derailleur, Sugino 34-46t crankset).

Threads like this should be banned without pictures. Let's see the Mercian in whatever state it's in! I hope it's BR green. Or another color...
