Making a great full-suspension race bike is a balance of contradictions. It has to be very efficient, very laterally stiff. It also has to be light and responsive. Tricky—but give Gary and a few good engineers enough time and caffeine, and barriers start to fall.
Go single pivot, because multiple pivots add flex and weight. Maximize the tubing size, and the width of the interface between the mainframe and the swingarm. Wider is stiffer and does not add weight. Design a linear shock progression to make it easy to set up, ride predictably, and use all of the travel effectively. Dial it in to match Genesis Geometry when a rider is sagged into the suspension, not when the bike is sitting on the shop floor. How about a narrow Q-factor, similar to that of a road bike? It's a more efficient pedaling stance.
The beauty of the Race Day platform is not one big revolution, but rather the compilation of everything Gary has learned over the years in one ultimate platform. It's twenty or more small innovations, all combined for the first time in one comprehensive design that is fast.
