I have an 80's Schwinn Traveler that's set up for half step + granny. 26-44-48 x 14-28 five (5) speed freewheel. I'm using a Cyclone GT in back and a Suntour Compe up front with Suntour barcons.

I never tried it with a bigger ring and the 26, it'd be close but it might work. The half step is a joy with the barcons. It handles the 26-44 shift nicely. This derailleur's been tweaked a bit, a little bending at forward end of cage, and I think a washer or two with spacer to widen cage at rear. On my bikes I only use the reverse acting Suntour front derailleurs with barcons. So it seems normal to me!
