I've ridden the wheel for two long work-outs since I got it back from the mechanic, and it works great! I didn't even have to do a manual zero of the power meter. Apparently, all it takes to overhaul the hub is to have an experienced mechanic--or even an experienced amateur--do the work. So, I have no idea why Saris insists on having customers send their wheels to Wisconsin--unless it's just to make more money...
