"The new track setup takes advantage of the narrow spacing and reduced chain pin length of 11 speed chains"

Spec'd & priced at the elite track racer level but
finally a new-ish take on the venerable FG drivetrain.
"The Kappstein Pro Line chainrings and cogs were raced by the Germans in Rio where Kristina Vogel won gold in Women’s Sprint, and picket up a Bronze in the Team Sprint together with Miriam Welte. Obviously the ring and cog then have been designed to handle the most extreme forces on the track, so paired with a top-notch 11 speed chain, they should be up to the task of cruising around town under your non-Olympic medal winning legs."
Indeed.
I'll stick w/ an old 48T NR road chainring & 1/2 x 3/32 NOS Sedisport chain but this is just Cool.
