GSI RKR Rotary Knob

Swap your wheel’s current rotary knobs for the RKR and add a splash of color. Each knob is machined from a solid block of 6061 aluminum for smooth, precise rotation, then anodized in teal, blue, gold, black, red or purple.

Fitting is simple: loosen (don’t remove) the grub screw on your existing knob with a 1.5 mm hex bit, swap in the RKR and tighten its pre-installed grub screw without over-tightening. It fits the Hyper P1, Hyper SL, GT-MAX32, FPE V2, GXL V2, X-29 and Interlock.
