G.Shim reduction sleeve

G.Shim reduction sleeve for seatposts.

The diameter just won’t fit? In other words, is there play between the frame seat tube and the seat post? Does this make it impossible to fit the seatpost correctly because it is too small? Then our high-quality G.Shim reduction sleeve for seat posts provides a quick remedy! Simply inserted into the seat tube, it allows the inner diameter of your frame’s seat tube to be precisely matched to the outer dimension of the seat post. The ingenious design of the double-slotted aluminum reduction sleeve promises stability and guarantees even, gentle transmission and distribution of the clamping forces thanks to the material-locking connection. The G.Shim version for reducing a 34.9 mm seat tube diameter to 31.6 mm allows standard dropper posts to be fitted to mountain bike frames with a 34.9 mm dimension. If the height of the seatpost is adjusted or removed, the lightweight G.Shim remains firmly in position in the seat tube due to its preload.
