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

New in, the improved version of the original Shockstop PRO V1. More comfort at the saddle means you’ll be able to ride longer, go faster, and maintain control even on the roughest terrain. The minimal, lightweight design of the ShockStop PRO V2 Suspension Seatpost blends seamlessly with the aesthetic of modern gravel and road bikes.

Benefits:

• Race-tuned – the combination of coil springs and elastomers provides a progressive spring rate that lets the suspension work effortlessly to absorb the bumps and buzz of gravel or road riding, while still providing a firm foundation to maximize power delivered to the pedals. The PRO seatpost disappears into the background, letting you stay in control and focused, while leaving you less fatigued after every ride.
• PRO Level – up to 25% weight reduction (130 grams!) from standard ShockStop Seatpost and ultra-sleek styling
• Go farther – reducing fatigue from bumps and vibrations
• Ride faster – energy that is normally wasted suspending your body is converted into forward motion
• Improve control – float over obstacles
• For the ultimate suspension system, pair with the ShockStop PRO Stem or ShockStop Stem
