RoadForce 35
Your handlebar stem can change the behavior of your bike completely; the angle, length, and stiffness make all the difference. The RoadForce 35 has a 7 degrees angle that makes your handlebar drop or rise, according to what you prefer. The RoadForce OS is available in 2 different sizes to make sure there is a stem that suits your position. The Roadforce 35 is certified for e-bike, road, touring, and mountain bikes. You got the power to control, we provide you with the tools.
Size guide
Every type of stem comes in different length sizes (mm). The stem length affects both your bicycle's handling and your riding position. The length of a stem is measured from the center point of the steerer tube to the center point of the handlebar. Shorter stems (40 - 80mm) offer quick, responsive steering, coften featured on mountain bikes. Longer stems (80 - 130mm), often used on road bikes, improve stability at higher speed. Gravel bikes typically fall in between, balancing agility and control with stem length (60 - 90mm).
The stem also influences riding position, mainly your reach. A longer stem extends your arms forward, resulting in a more aerodynamic position with your upper body folding over the bike. Conversely, a shorter stem allows for a more upright riding position with your hands closer to your body. For the best fit, we recommend a professional bike fitting or consult your bike’s geometry before selecting a stem length.

Steerer tube diameter (mm)
The steerer tube diameter refers to the size of the fork’s tube where the stem is clamped. This measurement is important for ensuring compatibility between your fork and stem. So, make sure you know the size of your steerer tube when selecting a new stem or headset for your bike. Common sizes are 25.4mm (1.0"), 28.6mm (1 1/8") and tapered designs that combine both.
Handlebar center diameter
The handlebar center diameter refers to the size of the handlebar where it attaches to the stem or another accessory. This diameter can vary between different types of bikes. Common sizes include 31.8mm for road bikes and mountain bikes, and 25.4mm for trekking and city bikes. Check your handlebar's center diameter to ensure compatibility when purchasing a new stem.
Stem angle
The angle of a cycling stem, or 'rise,' impacts your riding position. A 0º stem is perpendicular to the steerer tube while positive angles like +6º, raise your handlebar creating a more upright fit. Flipping the stem or using a double-angled stem creates a negative angle for a more aerodynamic position. Our range includes stems with varying degrees from zero to -40º to +60º.
