Redshift recently released the ShockStop PRO Suspension Seatpost RT, which is aimed squarely at high-performance gravel and road riders looking to stay comfortably in control over rough terrain. Get the details of their new lightweight design here…

Positioned as a high-performance option in their ShockStop Suspension System line-up, Redshift Sports just released the Shockstop PRO Suspension Seatpost RT, which saves an impressive 25% (or 130 grams) of weight over the original ShockStop Suspension Seatpost while retaining all the benefits of the parallelogram linkage for riding further and more comfortably over rough terrain. On the outside, it keeps the same minimal design that aims to blend seamlessly with the aesthetic of modern gravel and road bikes. Inside, the new Pro RT features a redesigned elastomer-based suspension with 20mm of travel versus the 35mm over the original coil-sprung model. According to Redshift, this provides “the right amount of suspension for high-performance gravel and road riding.” It’s also undoubtedly responsible for the majority of the weight savings.

Suspension designs based on elastomers usually rely on swappable elastomer elements to dial in the system for different rider weights, but Redshift says the natural progression of the elastomer elements in the ShockStop PRO RT renders this unnecessary for the applications where they envision the PRO RT excelling. With its maximum travel of 20mm, this lightweight suspension post is designed to dampen high-frequency chatter from gravel and not absorb big hits, so the progressive elastomers are optimized to ensure buzz-free riding up to the maximum rider weight of 242lbs/110kg, though Redshift does offer stiffer and softer replacement elastomers on request. The Redshift Shockstop Pro RT is available in 280mm and 350mm lengths for 27.2mm seatposts (shims are available from Redshift).
