| Features | 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. Control Taper 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. 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. UHC Performance UHC Performance is a T700- based blend of raw carbon fiber, which has a tensile strength that’s 7.9 times greater than 3/2/5 titanium and a stiffness rating that’s 3.34 times greater than 6061 aluminum. UHC performance brings the unmatched performance of a Felt carbon fiber bike to more affordable pricing levels than ever before. |
