GSI SRK2 Rotary Knob

The SRK2 is an easy way to personalize the rotaries on your GSI wheel. It is cut from a solid block of 6061 aluminum for smooth, precise turns and comes anodized in red, blue or black.

To fit it, use a 1.5 mm hex bit to loosen (not remove) the grub screw on your current knob, slide the SRK2 into place and snug down its pre-installed grub screw, taking care not to over-tighten. It fits the Hyper P1, Hyper SL, GT-MAX32, FPE V2, GXL V2 and X-29.
