Azarxis 17° 80mm Stem — 31.8mm Bar
The Azarxis 17-degree stem is crafted from high-strength 6061 T6 aluminum, combining durability with light weight. It supports 28.6mm steerer tubes and 31.8mm handlebars, and offers an adjustable angle from 0° to 17°. A four-bolt clamp design ensures a secure connection to the handlebar, helping maintain precise steering under load. This stem is suited for BMX, MTB, and road applications where a compact rise and strong clamping are critical.
FOMTOR 17° 90mm Stem — 31.8mm Bar
The FOMTOR 90mm 17° stem fits 31.8mm handlebars with a 28.6mm fork diameter. It provides a ±17° adjustability and weighs around 0.28 lbs (135g). Its lightweight aluminum construction supports agile handling while maintaining strength. The stem is designed to move the bar height up or down as needed, making it a good choice for riders seeking a more aggressive or relaxed riding posture without heavy hardware changes.
BESNIN 130mm 17° Stem — 31.8mm Bar
The BESNIN stem delivers a longer reach with a 130mm length and a 17° angle, suitable for riders who want a more relaxed position or extended handling leverage. It uses 31.8mm handlebar clamps and 28.6mm steerer compatibility, with an aluminum alloy body that offers good strength without excessive weight. The model notes emphasize the importance of choosing the correct model for individual needs, especially for longer frames and varied riding styles.
WAKE MTB Stem 70mm — 17°
The WAKE 70mm stem combines a compact footprint with a 17° rise, designed for efficiency on mountain bikes and cross-country setups. It fits 31.8mm handlebars and 28.6mm steerer tubes, with a hollow design to reduce weight. A four-bolt clamp keeps the bar securely in place, contributing to stable steering and quick handling, especially on technical trails where precise control matters most.
CYSKY 120mm 17° Stem — 31.8mm Bar
The CYSKY 120mm stem offers an extended reach with a 17° angle and robust construction from high-strength 6061 T6 aluminum alloy. It supports 31.8mm handlebars and 28.6mm front fork stems, delivering corrosion resistance and reliable performance in varied riding conditions. The longer length is well suited for riders needing more room to maneuver on larger frames or aggressive riding stances.
Buying Guide: How to Choose a 17° Bike Stem
- Compatibility: Verify handlebars are 31.8mm and forks/stems are 28.6mm to ensure proper fit with the chosen stem’s clamp and interface.
- Length vs. Reach: Short stems (e.g., 70–90mm) provide quicker steering and a more upright position, while longer stems (110–130mm) extend reach for a more aerodynamic or comfortable posture on larger frames.
- Angle and Steering Feel: A fixed 17° angle changes handlebar height relative to the steerer tube. Consider whether you want a higher or lower bar position and how that affects balance on climbs and descents.
- Material and Weight: Aluminum alloys like 6061 T6 offer strength with light weight. Hollow designs reduce weight further but ensure structural integrity for your riding style.
- Clamping System: Four-bolt clamps typically provide solid bar security, reducing bar slip during aggressive riding or jumps.
- Intended Use: For MTB and BMX, prioritize stems with robust clamps and corrosion resistance; for road bikes, consider stiffness and aero considerations in alignment with your riding goals.
- Installation Considerations: Check the steerer compatibility and ensure the stem’s centerline aligns with the fork and headset for neutral steering—avoid misalignment that can cause handling issues.
Overall, selecting a 17-degree stem involves balancing length, reach, weight, and compatibility with your bike’s geometry. The five products highlighted here provide a range of options to suit different preferences, from compact 70mm stems to longer 130mm models, all with a 17° rise that helps customize your riding position without major frame modifications.
