AeroPod, PowerPod and Newton

You need to look at your CdA and Crr values... the other numbers depend on individual unit calibration and so are not comparable. Also, the vibration/tilt phenomena will *not* effect the average power for a ride. The auto-tilt adjustment sees to that. So if you are seeing higher averages, something...

Update: I just completed my first significant distance ride after tightening down the clamp further and I have to say that, overall, the problem of power dropping off seems mostly resolved. The only reason I say 'mostly' and not 'totally' is that I did notice it would still drop off when I would hit...

The sticky tape from 3M works OK (you may have run across this stuff with many other possible applications and uses besides this particular one), but if you do use it, you really have to be extra carefu,l as noted, about tightening the screws too much. Plastic with that torque or deformation pressu...

Your aero is fine; you are a small and very light person! You bring up a good point about your mount. Make sure that your mount is tight enough so that it cannot rotate AT ALL on the handlebars. The double-sticky tape helps in this regard. Tighten the screws enough so that the mount doesn't move, b...

Thanks for the info John. I updated the Fric coefficient as you suggested in step one (set to 'yes' and '80'). This seemed to help the power from dropping off so much on the bumps. Now my coefficients are as follows: Cst (Aero) = 0.217, Cst (Fric) = 5.659. Should I try to tweak my 'Aero' to get it h...

Update: I decided to redo my 'other' profile by redoing the 'fast start' data, tilt cal, wind cal, and cal ride. The wind was nearly calm this time when I was doing my cal ride (of about 2.5 miles total). I made sure I hit some of the regular bumpy surfaces rather than trying to stay on smooth surfa...

I've been using my iSport for about a month now, and have noticed that the power readings seem to drop 30-70W when I hit a bump in the road, and drop off even more when I ride continuously on a poor road surface. I have the green sticky pads installed the way the directions say, and the unit tighten...
