AeroPod, PowerPod and Newton

Does the wind in this ride look correct? This was a group ride with drafting. I have noticed that my trainer rides have a higher average output than my outside rides.

Thanks, Brad

I think your outdoor ride is fine but that your indoor trainer watts are high.

On your indoor trainer you have a section where you average about 20 mph and average watts are about 252. This may be correct for your trainer but that's a pretty intense trainer.

On outdoor rides, on the level, with no drafting, I find that 20 mph requires about 200W. This rule of thumb is in line with your outdoor results.

Ok great! I am using a Kurt Kinetic (6lb weight), and I loaded up the KK profile from iBike software. Does the trainer profile need to be modified?

Thanks,
Brad W.

Every iBike is different and every placement of the iBike is different - as are the riders and their positions and riding styles. So every iBike gets a different calibration.

You cannot possibly think that a trainer is reproduced exactly every time they make one? The power curves the manufacturers supply are typical, not customized per trainer. Many are set up to mimic a 1% grade not flat land, too.

Use the trainer and power readings as a day to day relative measure. Set your workouts relative to that and not some fantasy absolute number.

Same thing goes for tires - even the ones on your car - you make enough of a change to them and you may not record your speed correctly or you may change your gas mileage.

All in all - don't be hung up on the absolute number, but train relative to them - they get better - you get better.

Agreed, thanks for the input. I will use it in that manner.

Thanks for all the support, I really enjoy using the iBike!
