Extralite Octaramp Road Chainrings

$158.00

Extralite's series of road chainrings are available for compact 5-bolt, 110 BCD cranksets. These chainring sets offer the best possible compromise between lightweight design and accurate shifting performance. Elegantly machined and hard anodized in black, Extralite rings feature intelligent tooth profiling and shift ramps for chain engagement in 8 different crank positions for the quickest possible upshifts. These are compatible with all modern road drivetrains, including Shimano, Sram, and Campagnolo 10, 11 and 12 speed systems (though they are NOT compatible with Campagnolo or Shimano 11 compact cranksets).

Options

RC2 - Road Compact - 50/34 - industry standard compact chainrings

CH2 - Compact High Ratio - 53/39 - a conversion chainring set to allow the higher gearing found on a 130 BCD crankset

MC - Medium Compact - 52/36 - a good balance between compact and standard sizes
