Why Octagon
Octagon is the first ever handlebar height adjuster that combines a simple, tool-free adjustment system with up to 3.5 inches of adjustable length, all the while assuring handlebar trueness. Octagon offers all the benefits of an angle adjust stem without shortening reach when raised.
This unique design allows for handlebar height to be changed while preserving the way the bike handles and rides. The octagonal shape of the post also keeps the steering engaged while raising or lowering the stem.
No Tools Needed
Up to 90 mm (or about 3.5 inches) of handlebar height adjustment made available without the use of tools. This allows the rider to find the most comfortable riding position to fit the current riding conditions.
Ergonomics
Octagon provides the rider with a more upright and ergonomic riding position at the push of a button. This allows for a range of riding positions ideal for those who use the same bike for multiple purposes.
Same Weight or Lighter
Octagon is the same weight or lighter than other commonly used components such as the standard quill stem, angle adjust quill, and angle adjust threadless extenders.
Reach
Octagon does not shorten reach with extension. This keeps your arms in a comfortable position and preserves the designed geometry and handling of the bike.
Compatability
The Octagon is compatible with 1-1/8″ threadless steel steerer tubes and standard direct connect stems allowing for a wide variety of aftermarket options.
Adjustable Length
The Octagon offers up to 90 mm of adjustable length. This ensures that the right handlebar height is at the ready for all riding conditions.
Octagon Shape
The torsional rigidity of the Octagon comes from its unique shape. The Octagon mimics the relationship found between a hex wrench and a hex bolt; allowing vertical movement with no rotational play.
Aesthetics
The Octagon is a more attractive solution than stacking multiple spacers to achieve the desired handlebar height and can be hidden by simply lowering the height.
Tool Free Adjsutment
Up to 90 mm of handlebar height adjustment made available without the use of tools. This allows the rider to find the most comfortable riding position to fit the current riding conditions.
