Duo Renthal's revolutionary Duo stem combines high strength with ultra-low weight. The stem is horizontally divided, allowing it to be machined in two pieces. This method gives unrestricted access to the stem core, enabling weight to be reduced to the absolute minimum, without compromising strength.
In addition this provides an uninterrupted U-shape clamping area, which eliminates the stress risers found on most other stems, which can lead to handlebar failure.
CNC Machined The Renthal Duo is fully CNC machined from a solid billet of 6082 T6 aluminium. The material was specifically chosen for this application to give the highest strength to weight ratio.
Horizontally Divided Unique to the Duo, the horizontally divided construction has allowed access to the core of the stem to remove the maximum material possible, whilst maintaining maximum strength and stiffness.
U-Shape Clamp An uninterrupted U-shape clamping area cradles the underside of the handlebar, eliminating the stress risers found on most other stems, which can lead to handlebar failure.
High Quality Finish After CNC machining, both halves of the stem are anodised and laser marked to give a very high quality, durable finish.
