The new Rival eTap AXS groupset allows for shorter chainstays and wider rear tires. Frame fit specifications can be found on the service portion of the SRAM website. Rival eTap AXS wide front derailleurs and wide spindle 43/30T cranksets, or Rival 1x wide spindle cranksets which are new for 12-speed, fit even wider tires than what has been possible previously.
