Replacement adjuster knob assembly for the top of a Future Shock 3.3 cartridge.
Future Shock 3.3 compression can be adjusted on the fly from soft to firm. Compression on Future Shock 3.2 cannot be adjusted while riding—it’s pre-set to the smoothest ride. Both shock springs and preload can easily be tuned by the rider prior to riding.
Riders can tune how Future Shock 3.3 and 3.2 react to bumps based on their terrain and riding style. Three different springs are offered - firm, medium, and soft - and up to five preload washers can be used, all easily adjusted at home. If you can remove a stem, you can dial in a Future Shock.
Roubaix was born for northern Europe’s challenging roads and rough weather, so Specialized made Future Shock 3.0 their most durable yet. Specialized has increased the boot’s thickness and added more seals to keep water and contamination out of the system.
Future Shock debuted back in 2016 and promptly proved its effectiveness by winning the 2018 and 2019 Paris-Roubaix. Sitting between the stem and head tube, it provides travel in the exact opposite direction of bump forces hitting the wheel and traveling up the fork legs. The result is an impact and vibration reduction of more than 50% versus Specialized's nearest competitors across impacts typically experienced by road riders. The result is more control to ride faster with more confidence on challenging road surfaces.
For the first time, the new Future Shock 3.0 can be easily tuned so every rider - regardless of position on the bike - can get 20mm of smooth, stiction free travel. Compared to the previous generation, Specialized has improved the overall durability, and made Future Shock 3.0 totally serviceable.
Features:
- The way Future Shock 3.0 reacts to bumps can be precisely tuned for the individual rider and the type of terrain they face. Three different springs are offered - firm, medium, soft - and with each of those springs, up to five preload washers can be used.
- As much as you can tune Future Shock 3.0, there are still times where you will want firmer or softer settings on the same ride. Smooth climb up? Keep it stiff. Rough descent down? Open it up. The 3.3 model delivers the most in the saddle adjustability of compression than ever.
- Future Shock 3.3 is hydraulically damped to control the movement of the Future Shock, not only for a smoother ride, but a more controlled ride. Highly tunable for the individual, riders can adjust pre-load to their desired firmness for their unique position or the terrain they are riding. Compression is highly adjustable during the ride to ensure that riders can set their Future Shock for the surface or the situation.
