Introducing the Octagon; the first ever height adjustable stem that combines a simple, tool-free adjustment system with up to 120mm of adjustable length, all the while assuring minimum insertion and handlebar trueness. The Octagon offers all the benefits of an angle adjustable 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. Also, with the octagonal shape of the post, steering remains engaged while raising or lowering the stem.
- Adjustable Length
The Octagon offers up to 120mm of adjustable length. This ensures that the right handlebar height is at the ready for all riding conditions. - Stem Compatibility
The Octagon offers several low profile stems that work seamlessly with the height adjust mechanism. That being said, most 1-1/8" stems are compatible with the Octagon for complete customization. - Reach
The Octagon stem does not shorten reach with extension. This keeps your arms in a comfortable position and preserves the designed geometry and handling of the bike. - Minimum Insertion
With a traditional quill-type stem, the rider can easily disregard minimum insertion. The Octagon features an automatic locking system that will not allow the stem to be raised past minimum insertion. - The Octagon
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. - Tool Free Adjustment
Up to 120mm 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.
