What Our Gearhead® Experts Are Saying: "I run the XC 1. 5 Stem on my Scott Spark RC and it’s ideal for XC racing. The low stack and aggressive negative rise give me the exact cockpit feel I need for climbing efficiency and cornering control without compromising stiffness."On race day or high-speed trail sessions, we count on the Syncros XC 1. 5 Stem to keep our cockpit low, stable, and responsive. Designed for the 2021 Scott Spark RC, this stem matches our need for aggressive geometry and lightweight performance, helping us stay efficient and composed when the trail demands max effort. Its forged AL7050 alloy construction keeps weight low without giving up stiffness, while a consistent stack height across all sizes helps us change stem lengths without impacting fit. The XC 1. 5 Stem’s negative rise varies with size, keeping us low and fast whether we’re sprinting up climbs or carving through berms. With a closed faceplate design and corrosion-resistant hardware, it’s a race-tuned component we can trust to deliver, lap after lap.
