Circuit Sphere 100 Shift Knobs 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. 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.
