Redshift ShockStop PRO Endurance Seatpost
Couldn't load pickup availability
The Redshift ShockStop PRO Endurance suspension seatpost is a choice for riders seeking plenty of travel in a lightweight package: 35 mm of damped suspension, weighing 445 g (280 mm) or 502 g (350 mm), with a diameter of 27.2 mm. Stiffness is highly adjustable and the design is slim. The system is designed to absorb bumps while retaining small-bump sensitivity.
It combines coil springs and elastomers for a more progressive response and controlled travel. The elastomers and springs are interchangeable, and preload adjustment lets you tune the feel. The seatpost comes pre-assembled with one red elastomer (medium), one green elastomer (soft) and two coil springs. The 280 mm version is not compatible with Di2, so check your setup before buying.
