SF25 DUROLUX38 EVO BOOST EQ RC+ PCS 29

SR SUNTOUR DUROLUX38 Gravity Has Met Its Match When the mountain throws its worst at you, the DUROLUX38 throws it right back — with more speed, more control, and more confidence than ever before. Designed for the steepest lines, deepest compressions, and heaviest hits, this is SR SUNTOUR’s flagship enduro fork , reengineered to push boundaries on every descent. Big Stanchions. Bigger Performance. At the core of the DUROLUX38 are massive 38mm A7000-series alloy stanchions , paired with a hollow-forged crown and wide-pitch chassis for unrivaled stiffness and steering precision. Now lighter by over 200 grams , it’s more responsive and nimble without compromising on durability. RC+ Damping: Fast, Fluid, Fearless Developed through our elite WERX program , the new RC+ PCS Cartridge delivers our most responsive damping yet. A semi-open oil bath design increases oil flow, giving you buttery small-bump feel, rock-solid mid-stroke support, and big-hit control — all with fewer external adjustments and more meaningful performance. External Rebound & Low-Speed Compression Internal High-Speed Shim Stack Tuning QSP Ports for Easy Serviceability SKF Seals for Reduced Friction & Extended Life Engineered for Extremes A new 3D-machined bushing alignment system ensures ultra-smooth operation straight out of the box. Add an integrated fender, proven DUROLUX pedigree, and pro-level tuning options — and you have a fork built to go fast, stay composed, and take the hardest lines with ease.
