ZSPEC Design’s weighted shift-knob (~207 grams). Knob is constructed of Delrin polymer with polished stainless-steel base.
Designed for extreme comfort – never too hot or too cold unlike solid-metal shift-knobs. Unique top “coin” offers either “ZSPEC” logo or 4-Speed shift pattern options.
Installation is a breeze, screws on to an M12-1.25 threaded shifter with ease. Coin adheres in place as desired with pre-installed 2-sided 3M tape.
Shift knob is 76mm tall (from base bottom to top).
Enhance your ride with ZSPEC.
