Warp 9 Altis Sigma Steering Cap Nut – Lightweight Aluminum Upgrade

A machined aluminum replacement for the bulky steel steering cap nut on the Altis Sigma. It does the same job at less weight, and it tidies up the top of the triple clamp, which is the one part of the front end a rider looks at on every ride.

An integrated set screw locks the nut against the triple clamp so it cannot back off under vibration. The finish is anodized, which resists corrosion and lets it be matched to the rest of the cockpit; seven colors are offered. Set steering head preload with the stock adjuster first, then snug the cap nut and tighten the set screw last.
