FSA SUPER ROAD CHAINRINGS
FSA makes replacement chainrings for their own cranksets, but they're also a great choice for Shimano cranksets as well. They're ramped and pinned, so you'll get top-notch shifting quality with no chain suck. The Super is made from CNC-machined AL7075/T6 alloy, with added material left in place near the interface points between ring and spider. This added material gives the Super added flex-resistance, ideal for hard accelerations. Please note that these rings are for double-chainring cranksets only.
FSA makes three Super outer rings: A 53t/130mm compatible with both Shimano and FSA non-compact cranksets; and 50t/110mm and 46t/110mm rings compatible only with FSA compact cranksets.
FSA makes four Super Inner rings: A 39t/130mm compatible with both Shimano and FSA non-compact cranksets; and 34t/110mm, and 36t/110mm rings compatible only with FSA compact cranksets.
