My ol buddy JC sent me this video about SRAM’s new mountain bike drivetrain called XX1. In the past mountain bikers have relied on 3 front chainrings to provide a wide enough gear range to climb steep technical climbs to bomb down high speed road descents. Improvements in drivetrain technology have rendered the triple crank obsolete as a 2×10 can provide just as wide range of gears with only two front chainrings. Now SRAM is doing one better, 1×11.
I really like seeing this because if you think about it drivetrains have only seen small incremental changes and improvements for 40 years. a triple crank touring setup from 1976 isn’t all that different from a triple crank setup now. Its time to start thinking outside the box and SRAM’s huge 42 tooth cassette does just that.
Of course I won’t be able to afford a 1×11 for years when they eventually trickle down the parts to lower end groups. I won’t be surprised if the POWERDOME 42-11 cassette costs more then my bike.
