Product Details

The Circuit Sphere 150 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. 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 150mm 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.

CIRCUIT SPHERE 150 \

The Circuit Sphere spawned from the idea of creating a functional, well designed and aesthetically pleasing shift knob intended for competition driving on the track or street. The marketplace is littered with competition shift knobs which lack engineering, testing and refinement to provide the best option to enthusiasts. We knew we could provide what the real competition driver is looking for so we set out to create a competition shift knob that delivers unparalleled performance and features compared to anything else on the market.

FORM + STYLE

Besides the steering wheel, the shift knob is the most driver interactive interior accessory but can have the least amount of integrated design. The Circuit Sphere flips that script and features a grip that has pure functionality integrated with visually stunning design language. The delrin grip has a sphere profile with a flattened top that allows your fingers to wrap over the sphere for a confident grip. The bead blasted texture enhances the grip, all while remaining cool to the touch. We designed an intentional tangent line around the grip which provides a subtle contour to unite your hand to the grip faster and easier. The final touch is a contrast cut Raceseng icon which visually pops against the satin finish of the delrin grip.

INTERCHANGEABLE

We designed our Circuit Series to be modular and have the flexibility of interchanging all available components. Individual Circuit Series parts can be purchased in our Component Shop to custom tailor the shift knob to you your needs and preferences.

NO SAGGY SHIFT BOOT

We hate sagging shift boots. Our adapters have a built in shift boot retainer section. Simply use the supplied zip tie to attach your shift boot to the adapter. When the shift knob is installed, it will sit flush with the top of the shift boot.
