SRAM are continuing to push the X1 technology further in search for ease of use and performance.
The new member of the X1 family is the XX1 Eagle, a 12x1 drivetrain designed to "work quietly, intuitively, precisely and perfectly."
SRAM are confident the new XX1 Eagle will deliver a 500% greater gear range and it's built to be compatible with existing SRAM products and also available in Gripshift.
