My Spot ACME has been working extremely well since buying in March '12. Took it into a LBS to have a bottom bracket re-pack after getting some knocking developing through the crank arms. They did the bearing re-pack and adjusted belt tension. After picking up the bike the next day, the problem was gone...but a new issue appeared:
They could not explain the damage...but have taken steps to source a new frame from the vendor in the States. They will swap over all my components.
I'm bummed, but at least they are moving the make things right....
