OneUp Components Launches 27.2mm Dropper Post

Press Release: OneUp Components

The OneUp Components V2 Dropper Post is now available in a 27.2mm diameter in 90mm and 120mm lengths for Gravel and XC bikes. At only 377g, the 90mm travel post weighs less than most 40mm droppers.

With the shortest stack height and shortest total length of any post with the same travel, no other dropper post can get your saddle lower.

The new size expands OneUp’s Dropper range, which now includes 27.2, 30.9, 31.6 and 34.9 diameters, with travel options from 70mm to 240mm in 10mm increments.
