Carbon Fiber Primus Wheel w/Knob 13.5" w/Santoprene Finger Grip 3/4" Tapered Shaft w/CF Nut

The Primus is manufactured using a unified investment casting, including the integrated ring, for massive strength. NMMA type-accepted and CE certified, it’s so strong, that it greatly exceeds ABYC P-22 and ISO 8848 standards. Polished to a mirror-like finish, the 316L stainless steel provides superior corrosion resistance and has minimal maintenance needs.

Available in 13.5″ and 15.5″ diameters, the rim is slightly thicker than most other wheels. At 1–1/8″, the larger size lessens the hand fatigue that’s common with thinner styles.

UV-resistant black Santoprene™ rubber provides all-weather control and comfort, and a dramatic counterpoint to the gleaming stainless steel. Underneath, finger grips deliver a sure, solid grip. It extends through the top of the rim, providing an additional gripping surface. The contiguous piece of Santoprene also extends slightly under the spoke junction for a smooth, ergonomic fit. The result is an attractive wheel that matches any helm décor.

The Primus is available in three spoke configurations: slotted with decorative Santoprene inserts, open slots, or solid. Edges have a slight radius for comfort, without sacrificing their markedly defined appearance.

The optional stainless steel Control Knob is large and comfortable. It’s installed on a spoke, 3/4″ from the rim edge, to ensure it won’t interfere with any controls or the driver’s helm space. The installation has no visible protruding fasteners to catch clothing or hinder the smooth tactile experience. Schmitt designed the knob with glass ball bearings to eliminate corrosion and provide a lifetime of free-spinning.

The Primus incorporates the industry standard 3/4″ tapered hub. The durable stainless steel center nut works with all steering systems, with optional styles available.
