A CatEye bracket (H-34N) is included as a bonus. ■ Cycle Computer Mount Lezyne Combo Mount Bolt Clamp Type For M5 stem bolts, with lower adapter LEZ-BOLT7+GP ¥5,280 There are some paint chips from use (front and back). See photos. ■ Light Adapter (Single Item) Conversion Adapter (Light Adapter) GP Standard For CATEYE (CatEye) H-34N compatible lights GP-CATHL2 ¥1,482 ■ Light Bracket (Bonus) CatEye Flex Tight Bracket H-34N ¥520 The screws are not original (lost during use). There are no problems with use. Purchased new in 2019. Used on a road bike for about 200km. It was then unused due to the COVID-19 pandemic and has been stored indoors. I liked it very much because it allows you to mount a cycle computer and light together, making the handlebars very tidy. As mentioned above, there are paint chips and minor scratches due to storage. Please refrain from purchasing if you are a perfectionist. I will sell it to those who understand that it is a used item. #rec-mounts #cyclecomputer #mount #roadbike #headlight #cateye
