A freeride capable stem in a cross country weight. The super stiff, torsion resistant body and wide faceplate provide more control on the trail while the flattened steerer clamp adds a little knee protection during unplanned stops. The Rhythm Pro stem also uses a unique bar clamp design which distributes clamping forces over a wider area for a longer lasting cockpit.
