Digging up an old thread that's just coming to fruition.... Congrats to OP @strand, and @dusty for their new Foes'. Would like to hear some feedback on how it rides (prob just Dusty right now until strand gets his built soon).
I've been dreaming again, though nowhere near pulling a trigger on something new. But very intrigued with the new for 2017 guerrilla gravity Megatrail and MT-SS. The MT and MT-SS are basically the same frame with a different length shock that converts from the longish 165mm travel MT, to the medium travel SS (SS=Slope Style or "short stroke") 135-145mm travel. And two different travel /geo modes for each shock option.
With all the different setup options, one could make this bike be anywhere from a 165mm travel "Endurish", decent pedaling option (Horst Link new for them this year), with easy conversion to a shorter stroke shock to 135mm Slopestyle bike or 145mm aggressive trail bike. I'm intrigued with all the variants, the SS "short stroke" mode can fit 29" wheels/tires, 27.5+ and regular 27.5. So with the two shock lengths and two travel modes, dif wheel sizes... lots of options.
Plus, made in America, Colorado, Aluminum
Boost 148 Rear, and metric shock spec....
