千呼万唤始出来Shimano Dura-Ace R9270 Di2开箱极速骑行2下载游戏探索自然的速

在这片蔚蓝的自然风光中,我们终于等来了一款极速骑行2下载游戏所需的Shimano Dura-Ace R9270 Di2开箱。作为代表着Shimano品牌最顶尖工艺和技术的公路套件,Dura-Ace无疑是Shimano百年庆最具分量的产品。

全新Dura-Ace R9200驱动系统牙盘组提供两个版本的选项,带内置集成功率计的选项(FC-R9200-P)和标准牙盘组选项(FC-R9200),当然还有很多不同的尺寸规格。两款链轮均采用HOLLOWTECH II(第二代中空技术),并提供50-34T、52-36T和全新的54-40T链轮片组合,曲柄长度为160mm至177.5mm,Q-Factor值为148mm。

功率计链轮版本兼容蓝牙和ANT+通信模式,用作数据传输。满电状态下的功率计可使用300小时以上,并进一步加强了功率计的精准度。

全新的Dura-Ace 12速HYPERGLIDE+飞轮保留了最小飞轮11T的齿数,但对第6、第7和第8飞轮片之间的最佳变速甜区进行了优化设计,从而保持Shimano飞轮片移动期间一如既往的变速流畅度。

得益于飞轮巧妙地倾斜倒角齿片旋转设计与快速、流畅的变速相结合,即使在高负荷踩踏之下,无论是向上还是向下变速,都可以实现更平稳的手感。这样带来的结果就是在变速时,不再需要停止加速度或减轻踩踏力量。得益于采用HYPERGLIDE+技术的心形刹车按钮,可以完全将力量专注于踩踏,并实现更快的手感变化。

全新R9200套件共有两个Dura-Ace HYPERGLIDE+飞輪選項:全新Dura-Ace 11-34T飛輪更適合陡峭的地形爬坡。飛輪設計有全新的塔基花键适配模式,与之前の11-speed塔基兼容,这也意味着升级到12-speed塔基结构不必担心旧有的问题。此外,还有一点提醒大家,11-speed 的飛輪无法安装在12-speed 的塔基上。

12speed 的tower structure upgrade to the new DuraAce suite offers several advantages, including improved compatibility with older components and a reduced need for replacement parts. This makes upgrading easier and less expensive for consumers.

The new STI shifters offer a more ergonomic design with increased grip and better spacing between the thumb lever and fingers. The buttons are also offset slightly to make it easier to distinguish between upshifts and downshifts, even when wearing gloves or in wet conditions.

Di2 technology allows for wireless connectivity between the shifters and derailleurs, making installation simpler and reducing clutter on the handlebars.

The battery life of the shifters is approximately 1.5 to 2 years, depending on usage patterns. However, users can opt for wired connections instead of wireless ones if they prefer longer battery life.

The derailleurs themselves have been redesigned with improved ergonomics and better integration into the overall system. They feature Shimano's Servo Wave technology for faster shifting action under heavy loads.

The brakes have also seen improvements with wider gaps between pads and rotors (10% increase) to reduce noise levels during braking operations while maintaining optimal performance levels.

In terms of wheelsets available from Shimano's DURAACE line include C36 lightweight climbing wheels; C50 all-around road wheels; as well as aerodynamic road wheels designed specifically for high speed riding.

C36: 1338g

C50:1465g

C60:1609g

As we eagerly await this latest offering from Shimano we cannot help but wonder what other innovations lie in store that will continue pushing boundaries in both engineering precision & rider experience!
