今天看到一篇有趣的比较文，对Tacx Neo系列有兴趣的人可以看看
其实会找到这篇文章是因为
发现我的NEO power(ERG mode,226W) 跟 P2 最近差了7~9W
让我感到怀疑人生...
所以在google可能的变因时，意外发现这篇文章...
大盘小盘不一样?! 嗯.....
Linearity Showdown: OG vs 2 vs 2T
https://tacxfaqx.com/knowledge-base/linearity-showdown/
文章的结论如下
If you’re going to use erg mode for your power based workouts,
we still recommend using the small chain ring and a straight chain line,
mid cassette, and occasionally vary the rear cog to distribute the wear
more evenly.
Start in the 21T cog and conduct your workout.
Next workout, shift to the 19T cog.
The next workout, shift to the 17T cog.
Then go back to the 21T cog and repeat for subsequent workouts.
This will keep your watts in a reasonable range while adding longevity
to your indoor drivetrain.
