Locking the chain and chainring together are CNC-machine teeth using variable thickness from tooth to tooth for impressive chain retention and a quiet ride. SRAM’s lightest chainring for their 12-speed Eagle groups CNC milling drop the weight by 8-10g compared to non-SL chainrings Tooth profile delivers smooth shifting and quiet operation You can expect long wear life and superb chain retention Ring swaps and installation is simple with the direct-mount interface 6mm offset for non-boost chainlines bikes with 12 x 142mm spacing
