For RST, the advantages of upside-down are obvious: less unsprung mass, better lubrication of the seals and therefore better response behaviour. The Rebel was originally planned as a cross-country fork. However, with the emergence of the Boost standard and the new Plus tyres, it was clear to the developers that the system offered the ideal basis for an all-round fork. The suspension travel of the Rebel can be varied internally between 80 and 140 millimetres and therefore offers space for wheels in all current sizes. There is also room for tyres up to 3.25 inches wide between the fork legs.
The 32-millimetre diameter dip tube unit on the Rebel is made of magnesium and manufactured from a single piece. Inside, there is a new air chamber with a separate negative spring on the left-hand side. On the right-hand side, the familiar OCR+ system provides the necessary low-speed compression stage.
The wheel is clamped in the fork via a two-piece axle. The thru axle provides the necessary positive locking with two small pins using the tongue and groove principle. The inside of the fork is prepared for Sram's torque cap system. The fork should weigh around 2.1 kilos in series production.
