Shimano 105 R7170 Di2 2x12 Speed Shifter
Function and technologies inherited from Dura-Ace and Ultegra, Shimano 105 is the culmination of years of research and development. With a shared Di2 platform, sophisticated ergonomics, Shimano 105-optimized gear combinations, and an exceptional brake system, the new Shimano 105 marks a new era of affordable performance. Sleek wireless cockpit brings simplicity and clean aesthetics. Wireless connection enhances the aerodynamic effect and easy maintenance.
Never skip a shift as you fatigue or encounter an unexpected climb. Worry-free Di2 shifting and a compact R7100 series shifter keeps you in control in any situation. The difference is made over the course of a ride, saving you energy with every gear change, allowing you to focus on the scenery, your effort, and your friends.
The all-new lever shape brings comfort and control in every riding position. Raised hood peak improves ergonomics, while a longer hood body increases hand support. Compact, ergonomic performance, custom button function and adjustable ergonomics cascaded from Dura-Ace.
Shifting is automatically completed at the touch of a switch, eliminating the need for the amount of stroke required for mechanical shifting. The rider can shift into the most appropriate gear at will, depending on the ever-changing conditions, speed, and road surface. This is a great advantage not only in the world of racing, but for all cyclists.
With a new piston design, race-ready braking is now available for even more riders. The new Shimano 105 BR-R7170 brake caliper allow riders to progress in their cycling journey by learning the joys of braking and pushing their limits with better sensitive braking control in a wider control zone and 10% wider pad clearance.
105 ST-R7170 is compatible with wireless connect and easy to change of CR1632 shifter batteries that provide high electronic energy efficiency of 3.5 to 4 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。
