Shimano Ultegra R8170 Di2 2x12 Speed Shifter Set
Road riding has never been this much fun. That's because the redesigned Ultegra ST-R8170 Dual Control Levers and BR-R8170 Caliper have unparalleled all-new ergonomics engineering refined with pros' feedback by raising the hood peak, even more precise brake modulation, quieter brake system, easier than ever bleed process, and wireless electronic shifting. This trifecta lets you focus on the next sprint, the next descent, or the next joke from your riding partner.
Sleek wireless cockpit brings simplicity and clean aesthetics. Wireless connection enhances the aerodynamic effect and easy maintenance. Shimano's new Ultegra ST-R8170 brake levers bring enhanced modulation and control to every ride by employing Shimano's proven Servo Wave technology. Ultegra BR-R8170 disc brake caliper provides a quicker initial braking point. Despite its smaller construction, the system is quieter than ever and easier to maintain.
The all-new Di2 platform, used on both Dura-Ace and Ultegra, untethers the shifters while delivering our fastest, most reliable wireless shifting. Your time on the bike is precious, let Shimano make it even better. Ultegra ST-R8170 is compatible with wired & wireless connect and easy to change of CR1632 shifter batteries that provide high electronic energy efficiency of 1.5 to 2 years of battery life.

Great product with super friendly staff. Definitely recommend to all
It works as wat is supposed to but loose on my most integrated bar but its suffice
Chain & cassette are super clean,,just as prescript to use, soak it for 2-3 mins; it would be better to use a toothbrush to brush through the chain & cassette. Thanks to the young staff who recommended.
你好！关于这个车灯，我的经验是：
对于山地车（MTB）骑行来说，我觉得这个灯是真的很好用。不过，如果是公路车，我个人就不推荐了。
完美整合： “我最喜欢的是它能完美地安装在 Quick Lock 手机支架的下方。Quick Lock 上面放着电话导航，而这盏灯就在电话下方，这样我的把横位置就非常整洁，一次性解决了手机和车灯的安装问题。
满足日常需求： 对于山地车来说，因为主要是在马路上保持能见度，提醒别人前面有车过来，这个灯的亮度是完全足够的。山地车在马路上速度一般也不会太快，所以它作为日常安全警示灯非常到位。不占空间： “这种整合式的安装方式，特别适合把横（车把）空间有限的山地车。
我不推荐给公路车的原因是：公路车速度快得多，如果晚上骑行或者需要照亮路面，它可能在亮度上会不够用，需要一个更强大、专用的照明大灯。这个灯的定位更偏向于警示/辅助照明。
