Renthal - Duo Stem (Bicycle)

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.


  • High strength and ultra-low weight combined with a low 40mm stack height make for a great all around stem
  • Stem is horizontally divided and machined in two pieces, enabling weight to be reduced to the absolute minimum without compromising strength
  • CNC machined from 6082-T6 aluminum alloy. 143g including bolts
