The SRAM X01 Eagle 12-Speed Grip Shifter brings things full circle, encompassing the company's groundbreaking new 1x12-speed design in the package that first brought SRAM into the limelight 30 years ago. Claimed as SRAM's founding product, grip shift has weathered the years, bringing back a nostalgic air of carefree neighborhood adventures during summer break, tenuous jump setups, and general two-wheeled glee.The internals have also grown up over the years to land at the top-tier of SRAM's off-road drivetrain offerings. Our childhood ideal of nylon bushings and plastic internals is replaced with three rows of stainless steel ball bearings and the rock-and-roll action of SRAM's Speed Metal alloy indexing. The Jaws lock-on grips maintain a secure hold on the shifting mechanism with corresponding teeth that are themselves locked into place with aluminum clamps.
