1957, My S-A AW3 , 3 speed, got a 3 cog cluster,& and a triple crankset... 3 cubed (3x3x3) is 27..
Now the R'off is 3 3 speeds - 2 redundant 2 nds, 7, x 2 (in low range) for IGH 14 speeds..
SRAM is Pushing and cashing in on this new one by obsession trend, closed several product lines to crank up the volume sold..
getting on that bandwagon is a choice..
