Syncros XC 2. 0 Stem Upgrade Your XC Ride Designed for the Scott Spark RC, the XC 2. 0 stems have a low stack height and negative rise for mountain bikers looking for a low handlebar position. Across the range of stem lengths available, only the reach changes as we have maintained the stack height across all sizes. The optimized aluminum construction achieves the perfect balance of strength, stiffness, and weight.
