???? Overview
A race-focused XC stem designed for the SCOTT Spark RC, built to deliver a low, aggressive cockpit position, precise steering, and lightweight performance.
⚙️ Core design philosophy
-
Low stack height + negative rise → puts your handlebars lower for:
- Better climbing efficiency
- More weight over the front wheel
- Improved aerodynamics
-
Consistent stack across sizes
- Only the reach (length) changes
- Keeps your vertical position consistent when adjusting fit
???? This is a very deliberate race-oriented design choice.
???? Key specifications
-
Range of use: MTB (XC / marathon)
-
Material: AL7050 alloy (high-strength aluminium)

⚠️ Trade-offs
- Aggressive position can feel:
- Harsh on long casual rides
- Too low for beginners or trail riders
- Not suited for:
- Enduro
- Technical downhill-heavy riding
???? Choosing the right length
-
50–60mm → aggressive, technical XC, quicker handling
-
70mm → balanced race setup
-
80–90mm → more stretched, stable, traditional XC feel
???? Bottom line
The Syncros XC 1.5 Stem is a purpose-built XC racing component—light, stiff, and aggressively positioned. It’s ideal if you want maximum efficiency and front-end control, especially on climbs and fast XC courses.
