采购商询盘内容
I recently purchased a bike suspension seat post marked with a diameter of 27.2 mm, and it came with a shim for fitting purposes. I'm curious to know if these seat posts are available in various diameters or if the shim is necessary for any diameters larger than 27.2 mm.
Additionally, can you provide more details on the available options for different diameters? This information would really help me in choosing the right seat post for my bike setup. Thanks!
我最近买了一根自行车避震座杆，标称直径为 27.2 毫米，还附带了一个垫片用于安装。我想知道这种座杆是否有其他直径规格，或者对于大于 27.2 毫米的直径是否也需要垫片。
另外，能否提供不同直径规格的更多详细信息？这些信息对我选择适合我自行车配置的座杆非常有帮助。谢谢！
