SRAM have bucked the trend of 11-speed cassettes and electronic shifting for their wholly revamped 2012 Red group, preferring instead to stick with 10 rear cogs and conventional cable actuation. The new 1,739g claimed weight lops about 150g off of what was already a superlight package and major improvements to the brakes, derailleurs and drivetrain provide better stopping power, smoother front shifts and quieter running to accompany the updated ergonomics.
[Outside of the front der, which seems like a nice improvement, I’m impatiently waiting for the hydro stuff.]
[Update: It seems that the front der. is not compatible with the previous shifters. These companies think they’ve created a gravy train by obsoleting designs every few years, but considering the cost of a gruppo in the aftermarket, changes like this just make me feel burned.]
