You may have issues with pedal based systems but since you are an engineer, you may appreciate that I have had 3 sets of bearings in my first hub and 2 sets in my second hub [SL+]. I would not buy another powertap hub since there is no real way to set up the bearings. I believe they have a poor design which loads the bearings too much. Maybe their newer hub is better, but I would not want to be the beta tester for that. The shipping alone cost me an additional $150 for the warranty work.

By the way, the first hub had less than 800 miles and had 3 sets of bearings, the second a little better at 1000 miles with two sets of bearings.
