Ever since bikepacking really took off a few years ago, brands have been trying to design the perfect saddle pack for dropper posts. All the while, what we really needed was a new dropper post design. Then came along the DT Swiss D 232 dropper post. Its inverted design allows for you to use ANY saddle pack. There’s no need for brackets or anything special. Use your normal bikepacking saddle pack and the D 232’s inverted topper provides enough space to strap it with no issue.
It weighs a mere 369g, offers 60mm of travel, and yes, it comes in 27.2mm clamp. See more at DT Swiss.
