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.

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.

By using a ControlTaper head tube with 1-1/8” upper bearings and 1-1/2” lower bearings, Felt is able to significantly improve front-end stiffness and steering precision without adding weight to the frameset.

Dynamic Monocoque Construction is a cutting-edge carbon fiber manufacturing technique that allows Felt to mold individual sections of the frameset and then join them with a special co-molding process. The primary advantage of DMC is that it allows each section of the frame to be optimized to meet the specific engineering demands of that particular section of the frame and to fully maximize the benefits of InsideOut technology.

Felt Active Stay Technology is a lightweight active suspension system created specifically for XC riding and racing. Featuring a lightweight, stiff carbon fiber rear triangle that doubles as a secondary spring to reduce unwanted bob without sacrificing small-bump compliance.

UHC Ulimate+ Nano is the mark of Felt’s lightest, stiffest, best performing frames. UHC stands for Ultra Hybrid Carbon, and as the name indicates these frames feature a hybrid blend of high modulus raw carbon fiber. The stiffest fibers are used in certain areas of the frame, more durable fibers in others. Nano refers to a proprietary resin matrix that increases frame strength at the molecular level.
