Gravel - Delrin Topper
KB-014-01015
This is a replacement or add-on topper for Kartboy’s StackLock shift knob platform. The Gravel is the cylinder-shaped topper. It threads onto a StackLock core and can be swapped with any other Gravel or Tarmac topper.
The Gravel shape is taller and narrower than the Tarmac. It suits a palm-over grip and sits higher above the shifter.
It is available in white or black Delrin. Delrin is an acetal plastic that stays cooler in summer and warmer in winter than a metal knob.
The topper requires a StackLock core, which is sold separately and included in every StackLock Shift Knob Kit. Hold the core with a standard 1/2" drive tool through its internal drive while threading the topper on or off. No special tools are needed.
