All new frame for this year offered in 6 sizes. The base of the frame is made of 6061 aluminum with custom Felt specs and a Felt Hydroformed top tube. Anyone can make an aluminum frame but with all of Felt’s experience with aluminum over the years we are really able to play with how a bike rides. The thickness of the tube, the OD of the tubing, the shape of the tube and the length of the butting all can change how the frame reacts. The geometry is very similar to the last design with just a slight rear end length tweak. Biggest changes are top tube shape, complete re-designed dropout/tensioner and a new sweet integrated seat clamp.
