When pedalling hard, you want your power to go straight through the pedals propelling you forward without any bob from the suspension. Then, when you hit the technical stuff you want your suspension to provide a smooth ride giving you more control as the bike stays in contact with the terrain you are navigating. In order to provide riders with that performance, Trek developed Reaktiv in a partnership with Penske Racing in 2014 to give riders a regressive damping suspension that responded to the terrain. The new Reaktiv Thru Shaft is the next development of the system to give riders a more responsive suspension and thus more control.
Trek have now debuted the Reaktiv Thru Shaft shock technology bringing it from the world of motor racing to mountain biking and doing away with the internal floating pistons used in most other systems. Fox and RockShox will be exclusively supplying Trek with the technology for 2018 and 2019.
The technology no longer uses an internal floating piston which creates a bit of a lag in the system when the terrain changes. The Thru Shaft technology is designed to improve responsiveness and in turn make the system faster at reacting to changes in the terrain Trek says. Trek’s new technology is designed to reduce the lag time and thus create a damper they say is faster at reacting than anything else available.
The Reaktiv Thru Shaft will be available on the Remedy 9.8, Remedy 9.8 women’s, Fuel EX 9.9, Slash 9.7, Slash 9.8. For frame sets it will be available on the Carbon Fuel EX, Carbon Remedy and Carbon Slash.
