Syntace Force 109

Strong and secure.

Equipped for oversized 31.8-millimeter bars, the Syntace Force 109 stem features 3D-forged aluminum alloy construction for the utmost in strength and security. Its thicker stem tube boosts stiffness and strength, with its oversized diameter continuing to the clamp area. Titanium bolts shave off precious grams, while the 200-degree handlebar "bed" reduces bar flex compared to stems with traditional 180-degree options. Ultimately, this allows your oversized handlebar to sit deeper and more secure, decreasing bar fatigue and flex over time.

The Best Stem

  • Familiarity: I've put it through the wringer

If only we sold it in -17. This is a perfect example of German engineering: simple, lightweight/strong, and very tight tolerances. Can't ask for more.

Great value

    Light weight at a great price.

    Bang for the Buck

    • Familiarity: I've put it through the wringer

    When push comes to shove, not many stems combine toughness and lightness (100g) as does the Syntace F109. Syntace pays attention to the details and abides to standards well above those required of them before allowing their products to find their way to market. For these reasons, the F109 been a staple in my bike stable for tens of thousands of miles (previously the F119).
