今天看到一篇有趣的比較文，對Tacx Neo系列有興趣的人可以看看
其實會找到這篇文章是因為
發現我的NEO power(ERG mode,226W) 跟 P2 最近差了7~9W
讓我感到懷疑人生...
所以在google可能的變因時，意外發現這篇文章...
大盤小盤不一樣?! 嗯.....
Linearity Showdown: OG vs 2 vs 2T
https://tacxfaqx.com/knowledge-base/linearity-showdown/
文章的結論如下
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.
