A good place to start learning about the iBike is the homesite! www.ibikesports.com From there you can find various discussion groups with lots of comparisons. The rough road issue has been resolved in the firmware upgrade 1.08. The fact that new firmware can be downloaded is a real cool feature of this unit, as firmware upgrades become available continously improving the operation. The latest version, 1.10 made the keypad work much better as an example. My exsperience with power in bunch riding has been very good as the windspeed measurement of the unit is very accurate. You only have to do a single "Coastdown" calibration with the unit in order to determine your aero profile. No need to repeat it again. If the team from Cycling Peaks are positive about the unit, something must be working.....
