    3-speed front gearbox in a crankset

    Has anybody heard about this 3-speed front gearbox?
    This guy from California's workshop seems to really like it. Not quite MTB stuff, but looks really nice for touring or commuting bikes.

    Haven't seen that one before but I have the FSA Patterson 2 speed internally geared crankset. I use mine with a single speed wheel for a 2 speed bike. Works as advertised and as someone who doesn't especially like derailleurs I've been quite happy with it. Being able to shift at a stop is really handy for me.

    Hey a 3 speed crankset that is interesting. So far I only knew the 2sp schlumpf crankset:

    I believe Schlumpf makes a internal crankset that is actually suitable for MTB, might be the 2 speed. I haven't tried mine on an MTB, it might work, but I don't think it's designed for that.
