Syntace stems – tested for the real world. Built for the extreme.
Every Syntace stem is tested on the world's toughest and most realistic test machine : the VR-3 test bench according to the demanding RC 2002.3 standard.
What this means? Stresses far beyond the norm – just like those encountered in real life: tough downhill runs, aggressive trail descents, endless enduro rides.
Where others only promise, we provide proof.
Trust the handlebars that the pros in the World Cup downhill also entrust their lives to.
Accessories – clever customization.
There are sophisticated accessories for all SYANCTE stems: From elegant spacers to different clamp variants and titanium screws to holders for navigation systems and smartphones – for a perfectly coordinated cockpit, both technically and visually.
Mountain bikes
MegaForce – powerhouse with safety guarantee.
Maximum stability and safety for aggressive trails. In downhill and enduro, every detail counts – especially safety. The MegaForce stems (available for 31.8 mm or 35 mm handlebars) offer maximum resilience and are designed to withstand extreme forces. Short, stiff, and precisely manufactured – for complete control and confidence on any terrain.
MegaForce 3 for classic 31.8 mm clamp.
MegaForce 3.5 for modern 35 mm handlebars – strong, stable and uncompromising.
Lightweight titanium screws as standard
This super-lightweight stem comes factory-equipped with high-quality Syntace titanium bolts. Compared to conventional steel bolts, they offer better corrosion resistance and significantly lower weight while maintaining the same durability.
Syntace 200° head with 4 screws
High, gentle handlebar clamping force. Better force distribution compared to slotted clamps.
Syntace VR-3 tested
The world's toughest testing standard for handlebars and stems. Tested with handlebars up to 800 mm and approved without restrictions. With titanium bolts and form-fitting Litecap.
Road/Gravel/XC
Maximum efficiency – minimal ballast.
The SYANCTE Road & Gravel stems set new standards in lightweight construction, integration and torsional rigidity.
Thanks to a shorter fork tube, clever flip-flop design and open front clamp, you save weight, time and material – without compromising on stability.
Our high-strength aluminum alloy, genuine 3D forging technology, and feather-light wide format make FlatForce and LightForce the smart lightweight stems for performance-oriented riders on asphalt, gravel, and off-road.
Titanium screws as standard
If you're looking for something truly lightweight, the Liteforce is the only way to go. In its shorter versions, it delivers direct handling on cross-country and gravel bikes. The longer versions (up to 135 mm) provide precise steering and efficient power transfer on road bikes. Weighing in at just 90 g (including TwinFix), the Liteforce is the first choice for anyone who wants a lightweight bike without compromise.
Flip-flop construction
The Flatforce was developed primarily to allow cross-country cyclists to maintain a sporty and efficient riding position despite large 29" wheels and increasingly longer suspension forks – without compromising on aesthetics, durability, or handling. The lower handlebar position can also be a real advantage on road bikes, gravel bikes, or even children's bikes, whether for improved aerodynamics, a more efficient position, or simply more control.
