This is a set of two WEST BIKING brand bicycle bar end mirrors. Compared to generic products, these have a slightly more stylish logo and are made with a bit more care. These are folding rearview mirrors primarily for use by replacing the bar end caps of cross bikes, road bikes, etc., and when not in use, you can close the cap and store the mirror. The hinge part is a ball joint, allowing for adjustment to various angles. Also, the direction of rotation can be adjusted around the central axis of the fixing bolt. The mirror is a convex mirror made of acrylic, which is less likely to break than glass, and is designed for easy rearward confirmation. This is one of several I obtained for a bar end mirror introduction experiment. It was difficult for me to use in my environment, so I will sell it to someone who can utilize it. Having a mirror helps with safety checks, and it can also be installed stylishly, so why not add it to your own bike? 【Product Information】 Function: 360° rotation, HD convex mirror, easy to install 【Specifications】 Material: Nylon + Fiber Color: Black Weight: Approximately 23g Handlebar Compatibility: Φ16-22mm Contents: 1 bicycle rearview mirror & 1 wrench × 2 sets ※ The internal collar expands and fixes when the cap bolt is tightened. 【Condition】 Brand new, unused. Due to being bulk imported from overseas, there may be differences in finish and actual measurements. Please understand this. 【Remarks】 The price is for a set of two. The unit price will increase due to shipping considerations, but single item transactions are also accepted. I am also selling some other bicycle accessories, so I would be grateful if you could trade together. 【Shipping】 The width is just barely within the limits, but it seems like it can be posted in a post size, so if you have no particular preference, it will be shipped via Yu-Packet Post Mini. I will take it out of the box and package it to prevent damage. If you cover the shipping costs, I will ship it via Takkyubin Compact, etc., so please consult if you wish.
