stiffer than ever
The biggest advantage of carbon wheelset is the unparalleled stiffness, especially, the lateral stiffness. This stiffness affects the riding experience.
With a 26” or 27.5” carbon wheelset, riders will not feel so much, because of the smaller wheel diameter. But when it comes with 29” wheel, riders would feel it remarkably.
With a bigger wheel diameter, without enough lateral stiffness, this makes riders feel floppy.
