- FSA TH-883 compressor for 2015 Krypton
While it’s common for endurance-oriented road bikes to have taller head tubes for a more comfortable riding position, the Krypton has its own unique solution to serving riders of different sizes and various positioning preferences. The 3D head tube system essentially lets you choose from three different head tube lengths for any given frame size (below).
The 3D system allows you raise or lower the handlebar position without relying on traditional headset spacers. According to Argon 18 test results, raising the bar 15mm lets you retain 5 percent more rigidity compared to standard setups. And raising it 25mm saves 11 percent.
