Shimano DA R9200和UT R8100的差别在哪里？为么说R8100真香

2021年9月1日，令人瞩目的Shimano Dura-Ace Di2 9200和Ultegra Di2 8100正式发布。虽然比计划晚了一年，但这次Shimano一下带给<span style="color: black;">大众</span>两个全新套件。Dura-Ace技术直接下放到Ultegra，让囊中羞涩的玩家<span style="color: black;">亦</span>能体验到全新的Di2平台。重量上的差别很容易了解，电子部分<span style="color: black;">亦</span>相同，<span style="color: black;">那样</span>它们还有<span style="color: black;">那些</span>细节上的区别呢？<span style="color: black;"><strong style="color: blue;">手变：ST-R9270 vs ST-R8170</strong></span>
