The Spanish company has not only slightly updated its design; a new tooth profile makes these chainrings compatible with Shimano HG 12-speed chains and, therefore, with the latest Shimano 12-speed road groupsets. Thanks to their 110-millimeter asymmetric bolt circle, the chainrings can be mounted on Rotor ALDHU/VEGAST cranksets and on all 11/12-speed Shimano road cranksets (including those with Shimano power meters).
