While not as light as the pure XC Next SL crank arms from Race Face, these UD carbon Next R's don't sacrifice much in gram weight while offering strength rated for Enduro riding. This makes them the perfect everyday XC Trail/Trail option for any rider. Featuring the CINCH design for the crank arm and chainring interfaces, the Next R is the simple and easy to set-up and use. The stout 30mm hollow axle gets the job done all day long, then the next, and so on. Proper installation using torque tools is crucial and we suggest checking the bolts again after the first ride to ensure the torque application has seated the arm on the BB spindle.
