The Redshift Shockstop PRO V2 Suspension Seatpost - 27.2 x 350 mm

The Redshift ShockStop PRO V2 suspension seatpost 27.2 x 350 mm at Rosiir delivers enhanced comfort and control for road and gravel, with 20 mm of progressive travel that smooths vibrations and reduces fatigue on long rides. The parallelogram linkage keeps the saddle level through its travel for efficient power transfer and a natural position, while the optimized PRO construction is lighter than the standard ShockStop without sacrificing stiffness or durability. Built from 6061‑T6 aluminum with a race‑tuned coil + elastomer setup, it filters small chatter and absorbs bigger hits; Di2‑compatible and easily shimmed to larger seat tubes.
