Everyone says iBike is inaccurate. But if you look at dcrainmaker review, magazines, youtube, etc... It seems pretty close to the big boys. I wonder just how much position changes and road surfaces effect the iBike readings.
If I get a decent used power tap, how much $ would I be spending? Can somebody list all the things I need to get a setup going? I would probably end up selling the wheelset I have (reynolds solitude) and upgrading to carbon while I'm at it, as I already have a spare carbon front zipp wheel. How much would the head unit cost? Does the hub need maintenance?
