Product Details

Circuit Sphere 100 Shift Knob by Raceseng®. The Circuit Sphere 100 fuses function, form and style together to create an unparalleled, performance enhancing and confidence inspiring shift knob. The ergonomically designed and textured sphere grip was designed for overhand shifting.


  • Provides an exclusive approach to define your interior
  • Functional, well-designed, and aesthetically pleasing
  • Intended for competition driving on the track or street
  • Sports the tall ball profile and unique performance features
  • 303 stainless steel handle, 6061 billet aluminum ring and Delrin grip

The sphere grip features a flattened top that nestles into the palm of your hand and allows your fingers to wrap over the sphere for a firm shifting grip. The stainless steel handle is appropriately weighted to remain delicate on your shifter linkage assembly and to prevent the numb feeling commonly found when the weight is set too high in the grip. The 100mm height reduces your hand’s travel distance and time between shifts while increasing your mechanical leverage and reducing the effort required for each shift throw. The shift knob was designed to reduce fatigue during repetitive lateral arm and shoulder movement between the steering wheel and shift knob.

This shift knob is nice to the touch. It has an ergonomic grip. Plus, the knob offers great performance - reduces the time between shifts. And it has a durable stainless steel handle. I also love the classic design and the deep black color.
