Extralite Octaramp RC2 Chainring Set

Detail
Extralite Road Compact chainrings offer the best possible compromise between lightweight design and accurate shifting performance. Elegantly machined and finished in black hard anodization, these chainrings offer intelligent tooth profiling and shift ramps for chain engagement in 8 different crank positions for the quickest possible upshifts. RC2 chainrings are compatible with all modern road drivetrains, including Shimano, Sram, and Campagnolo 10 and 11 speed systems (though they are NOT compatible with Campagnolo's compact cranksets).
