Duo stem

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.

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.     

CNC Machined

The Renthal Duo is fully CNC machined from a solid billet of aluminium. A multiple stage machining process ensures all unnecessary material is removed, to minimise weight, whilst retaining maximum stiffness

Aluminium Tech

The Duo is manufactured from high grade 6082 aluminium, which is heat treated to T6. The material and heat treatment processes have been specifically chosen for this application, to give the highest strength to weight ratio.

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.

Quality Finish

After CNC machining, both halves of the stem are separately anodised and laser marked to give a very high quality, durable finish.
