Suspension Bicycle Forks

The RockShox SID SL Ultimate BRAIN incorporates a race-tuned Brain Inertia Valve with Position-Sensitive technology into the all-new RockShox SID SL chassis. New Position-Sensitive Brain technology provides more platform support while maintaining small bump compliance and chassis balance, making this the most efficient BRAIN yet. Position-Sensitive technology allows riders to sag into the fork 15mm for a balanced ride, providing supple small bump compliance and a firm pedaling platform without the need for a remote lockout or levers to flip. All new SID SL Ultimate Chassis features a machined alloy crown to shed even more weight while increasing stiffness. - New Position-Sensitive tune provides an increase in platform support. - New SID SL Ultimate chassis features increased stiffness, lighter weight, and reduced friction. - Torque cap compatible for stiff dropout/hub interface. - 100mm travel, 44mm offset, 110mmx15mm hub spacing.

You’ve probably observed more and more riders are on bikes that look "different" on your trails. Bikes that have wheels and tires of gigantic proportion – and we’re not talking about 29ers here. The thing is, even though fat bikes were created to float on top of snow, they’re just too damn fun not to ride on dirt. So how do you amplify your fat bike adventures even further? With a supercharged, ultra efficient, first of its kind fat suspension fork called Bluto. We started with the features you’ve come to love from RockShox: Fast Black aluminum upper tubes, stout 15mm Maxle, remote or crown adjustable damping, tapered steer tube, and the infinitely tunable Solo Air spring. Then, the chassis got the fat treatment by re-engineering it to meet the unique needs of fat tires and wheels. Everything from crown, to arch, to axle has been optimized to tackle the increased torsional loads of its wide stance. With more traction and control than ever before, you’ll never be happier you went fat. - Updated air pressure guides maximize performance for E-MTB applications - Motion Control damping featuring 3-position compression adjustment (open/pedal/lock) - Updated graphic package to complement the RockShox lineup

The 40's GRIP2 damper delivers ultimate performance and control when the going gets rough. Equipped with the Variable Valve Control (VVC) high- and low-speed rebound adjuster, improved compression damping and less friction overall, the 40 is just as comfortable in the bike park as it is racing the World Cup circuit. "Factory" says it all. The best-of-the-best technology we have to offer is available in our Factory Series models with our buttery smooth, and ultra durable Genuine Kashima Coat. These products are World Cup proven. Buttery smooth Kashima's distinctive gold color is backed by its high performance attributes—properties that provide an exceptionally smooth feel and extreme durability. GRIP2 — Next-Generation Sealed Cartridge FIT Damper GRIP2 is our next-evolution sealed cartridge FIT system, our highest performing gravity-focused damper. The new damper shares its roots with the original GRIP architecture but has been seriously enhanced with all-new technology: 4-way adjustability, VVC high-speed rebound circuit, high-performance mid-valve, and overall friction-reducing treatments. EVOL — Air Transfer Port System Our EVOL linear spring curve gives forks and shocks plushness off the top, extra mid-stroke support, and more tunable bottom-out progression, allowing riders to tap into the ideal pairing of front and rear-end feel. FLOAT EVOL Air Spring EVOL technology from rear shocks is integrated into all FOX forks. EVOL increases negative air spring volume, specifically positioned and sized for optimum small bump sensitivity. - FIT GRIP2 damper with 4-way high- and low-speed compression and rebound damping - 29" wheel with 20mm Boost thru axle - FLOAT EVOL air spring - Air bleed system ensures consistent fork performance at any altitude - Factory Series models feature Genuine Kashima Coat
