The All-Packa comes in a 1x or 2x version. The 2x option is a reflection of the fact that the bike won’t accommodate the very large cassette ranges that are common nowadays on 1x drivetrains. That’s because the derailleur cage has to be relatively short to not put it completely in jeopardy. The biggest cassette gear will therefore be a 40. The one they sent me has a 42 chainring, yielding a combo that I found reasonable for loaded trips, but that for many won’t cut it going up the steepest pitches. On the other end, the 11-tooth small gear met my ambitions for going fast enough on the flats and downhills, but I could imagine some people finding it limiting. Clearly, that would get worse with a smaller chainring. A 2x therefore makes good sense. I can report, too, that having a front derailleur on one of my other Bike Fridays makes chain management when folded a little easier since the derailleur keeps the chain somewhat scooped up.
