FeaturesBayonet The Bayonet is Felt’s patented aerodynamic fork design for time trial, triathlon, and track bikes.  By moving the fork’s steer tube outside the frame we were able to increase front-end stiffness and steering precision, while dramatically decreasing wind drag. It’s the fastest, most aerodynamic fork and steering system in the world.

Wind Tunnel This product directly benefited form advanced computer design work using Computational Fluid Dynamic (CFD) software from CD-Adapco as well as extensive wind tunnel testing to make them as aerodynamically efficient and technologically advanced as possible.

Devox This indicates Felt’s exclusive premium quality component line Devox.  Every component with the Devox name was designed by the same team of engineers responsible for cutting-edge Felt bikes and technology.  When you see the Felt Devox name, you know that particular part or component is held to the very highest technological and performance standard.

Internal Cable Routing This indicates the use of flow-through internal cable routing.  It reduces wind drag and prevents contaminants from entering and interfering with the function of brake or shifter cables.

Inside Out InsideOut is a revolutionary internally optimized molding process that completely eliminates excess material, and therefore weight, inside the frame tubes and junctions.  Placing polyurethane inserts inside the frame during the molding process—especially at the bottom bracket and head tube area—and then applying  a precise amount of pressure and heat results in perfectly formed tubes, inside and out.

Modular Monocoque Modular Monocoque Construction (MMC) is an advanced carbon fiber manufacturing technique that allows Felt to mold individual sections of the frameset and then join them together.  The main advantage of MMC is that it allows each section to be optimized to meet the specific engineering demands of that particular section of the frame.

DuPont Paint Felt’s DuPont point is the highest quality paint offered on Felt products.  Reserved for our top-of-the-line bicycles, DuPont paint offers unparalleled clarity and durability in a multitude of colors.
