Good quality and reasonable price
$12 to bling up my bike, sure thing! Wanted to get the 60mm valves but gold was out of stock. Shipment was on the way butI couldn't wait. Always nice to catch up with the boys!
Wish that the chain came with missing link instead of pins
Very clean line, would buy it again
Great attractive bar tape! Nice to the touch andvery comfortable❤️
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。
Delivered as pictured, delivered in great condition, pleasure to deal with.
