## Overview

The Force 109 Bicycle Stem by Syntace is a lightweight, durable alloy stem designed for professional cyclists seeking customizable rise angles and a secure 4-bolt handlebar attachment. With a weight of just 129 grams (135mm length) and compatibility with standard 1.125-inch steer tubes and 31.8mm bars, it offers both performance and versatility for an optimized cycling experience.

## Description

With oversized handlebars being de rigueur for road and mountain bikes these days, you need a stem that is equally as stiff and strong. Syntace took the design of its legendary F99 stem and parlayed it into the F109, to fit oversized 31. 8mm handlebar clamps. Syntace forged the Force 109 from high-strength aluminum alloy. This material, along with 3D forging, keeps strength at a maximum and weight at a minimum. In addition, it's equipped with titanium bolts to shave every gram of weight possible. The faceplate makes handlebar changes quick, and you won't have to contort your fingers to squeeze a hex wrench into an awkwardly-placed bolt head. The "bed" for the handlebar is 20 degrees deeper than a standard 180, at 200 degrees. This allows your handlebar to sit deeper into the stem, which helps to decrease bar flex and increase fatigue life. The Syntace Force 109 Stem is available in several lengths and degree options: 60mm/6deg, 75mm/6deg, 90mm/6deg, 90mm/17deg, 100mm/6deg, 100mm/17deg, 110mm/6deg, 110mm/17deg, 120mm/6deg, and 135mm/6deg. It comes in the color Black.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Quality product !
*by D***. on November 5, 2012*

Satisfied ! installed it a few weeks ago. This is my first experience with a syntace product, and so far a positive one. This was a replacement for my FSA OS which I decided was a little too long for me (120mm). The 100mm F109 Stem seems to be well made, nicely finished and looks great,although the carbon face plate of my FSA did provide a visual advantage over the twin hollowed out aluminium semicircles used on the F109, but i guess the paring off of 50 grams had to come from somewhere. Installation went smoothly and there's no notice of flexing while riding, despite the ridiculousely light weight of the stem. I'm happy.

### ⭐⭐⭐⭐⭐ Great Product, Great Company
*by D***I on October 28, 2013*

This stem was as advertised. It is very light...yet, I think I and others can be confident that it will hold up knowing that Syntace is confident enough in their own product to offer a 10 year warranty! This is an aluminum part but they even offer the same warranty on carbon parts (I bought the P6 Hi-flex seat post)! I would recommend being extremely careful tightening the titanium bolts that come with this stem. If you follow the directions, using a torque wrench, and don't tighten them beyond 6nm you will be fine. If you don't have torque wrench or just don't want to hassle with it you should get some steel bolts. I forgot and was thinking it was 9nm and I snapped one off. If you've never tried to get a titanium bolt with no head on it out of a threaded hole take my advice...you don't want to. Nevertheless, the Syntace rep was VERY accomodating and sent me a new stem!!!. One other thing I like about this stem is the "snap fit feature". My bars actually snap in allowing for easy adjustment before tightening the bolts.

### ⭐⭐⭐⭐⭐ I bought this to match my new Syntace Seatpost and was gladly surprised!
*by M***. on April 26, 2014*

Guys, the quality of this thing is amazing. It's extremely stiff (I'm 210lbs and I ride my bike hard). It comes with nice Ti hardware and a nice stem cap! Oh, and it's also flip-flop (you can use it upside down for negative rise). I did replace a 110mm Thompson X4 stem with this one and to my surprise the Syntace was about 8% longer. This wasn't an issue because I was between a 110 and 120 anyway, but be aware of this when buying.
