Thank you for viewing! This is a brand new, unused item. The color is black. This product will be wrapped in bubble wrap for shipping. 【Size】The cargo bed is 12cm x 33cm and made of lightweight aluminum alloy. The structure supports the weight with just the lightness and the seat post, so the cargo won't interfere with the saddle when the carrier is extended. 【Bolt-on/Detachable】Attach to the seat post, and fix it with horizontal or sloping. It is recommended to attach it to the top of the seat post (just below the seat). It won't be bulky even if you lower the seat, and there's no problem when transporting the bike. If the difference in height between the rear tire and the seat post is narrow, the carrier may interfere. For example, if the rear tire is higher than the saddle, you cannot attach the cargo bed. 【Easy Installation】Includes a 5mm mini hex wrench *1 and rubber spacers *4. The spacers allow for secure fixing. Your saddle pipe will not be scratched. With the telescopic structure, you can change the length of the cargo bed by sliding the fixing bolt of the cargo bed slider and tightening it with a screw. Regularly tighten with the included tool. 【Notes】Compatible seat post diameter φ25.4-32mm, please check before purchasing. Use only as a cargo bed/carrier; do not use it for carrying people. Instant purchase is OK! This product is not subject to price reduction. #704150(870)
