KCNC K6 Oval Chainrings

Oval chainrings from KCNC for 110bcd 5 arm cranks.  Some call them a-symetric, some call them elliptical - but they are not round.  All are designed to reduce the effect of the "dead spot" as the crank arms come round top dead centre (12 and 6  o'clock).

They can increase power, they can increase efficiency, they can make you pedal smoother! 

KCNC use what they call an ovality ratio of 1:10  on the K6 Cobweb pattern rings, with a bi-radial symmetry offset by 102 degrees.
