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.

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).
