48-45-24. It came with 50-45-28, but I switched to a 7-speed freewheel and needed the extra low end. No problem with the chianring jump, though there is not enough RD chain wrap to use the bottom three gears of the freewheel with the granny gear...not a buig deal. I have found that the 80's Suntour Mountech front derailuers will take almost anything and seem to be pretty bullet prorf (the Mounjtech rear derailleurs are not so hot). I do not normally cross chain, but flipped it into low when I pulled into the driveway and did not notice which chainring I was in (the glories of half-step)
