SLX
With shift technology inherited from mechanical XT and XTR, Shimano SLX gives you top-shelf shifting at a budget-friendly price. Whether you're hitting the trails with friends or lining up for an XC race, Shimano SLX is a workhorse drivetrain that won't hold you back as you grow in the sport.
HyperGlide+
Shimano's HyperGlide+ shifting system uses machined ramp designs to smoothly guide the chain up and down the cassette for lighter, faster shifting, even under extreme pedalling force. A wide range of HG+ gearing choices, cassette options and the choice of a single or double front chain ring support a wide variety of riding styles, abilities and preferences.
Micro Spline
Shimano's Mico Spline lightweight aluminium freehub keeps your set-up featherweight and allows room for a small 10-tooth cog. Only compatible with Shimano Micro Spline cassettes.
