Mad Fiber’s prototype wheel with Kevlar fibers alongside the carbon fibers could let them potentially produce a sub kilogram tubular wheelset. The standard all carbon model is about 1,050g.
The red color comes from a dye in the Kevlar, and they could do other colors.
Performance benefits? They’re not sure yet, other than less rotational mass of course. It’s still in testing, but they’re looking for equivalent performance to their regular wheels, just lighter. Cost would go up, but numbers aren’t in place. Kevlar requires more finishing work because the edges don’t want to stay as clean when it’s cut, as on the spokes here.
