Altis Sigma Titanium stem nut +
$65.00
This beautifully machined Titanium stem nut replaces the ugly and heavy stock steel nut. There is a secret feature hidden on the bottom side of this nut that makes it different from the rest. A conical seat which interlocks with the upper triple tree removes any of the play and clunking the top tree had stock and helps keep the tapered preload spanner nut tight.
