Knuckleball (delrin 5spd) – You want a Knuckleball, but aluminum isn’t your thing? You’d rather have a lighter shift knob cause your car is on a diet? Fear not, Gram Counter… Kartboy has you covered.

This is the delrin version of our Knuckleball, and it weighs in at a scant 2.6 ounces – less than a deck of cards, cowboy.
