Why We Like The Race Face Next SL Crank Arms

Whether you ride a simple and reliable single-ring drivetrain, or prefer to run a traditional double- or triple-ring setup, the Next SL crank accommodates both. While a one-by uses a direct-mount chainring, a double or triple setup uses the Race Face aluminum spider that is sold separately. They are set into a 30mm spindle, 6mm larger than the previous version, which is fabricated from Race Face’s "super" aluminum, which is purported to be stronger than 7050 series aluminum. Less material and an oversized spindle ensure both a lower weight and increased stiffness—a winning combination for discerning riders and racers.
