The Renthal Apex combines All Mountain strength, Enduro stiffness and XC lightweight.

Unique 240deg handlebar clamps allow much of the stem body material to be removed, whilst retaining the strength and stiffness demanded by modern, wide handlebars.

The Apex is fully CNC machined, featuring an oversize centre bore, extensive 3-D machining and external webbing to maximize structural strength and stiffness and minimize weight.
