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.
E-bike ready
Products suitable for use on a wide range of bicycles, including E-bikes. Ensuring durability even at higher speeds and with heavier bikes. They meet the NEN-EN 15194:2017 standard for electric bicycles, covering safety aspects and hazard prevention. This e-bike-ready label guarantees your gear can handle the demands of (electric) cycling, providing peace of mind when you hit the road on your e-bike.
Di2 compatible
When a stem or handlebar is labelled as Di2 compatible, it means that it is designed to accommodate Shimano's Di2 electric-shift cable routing system. This allows for seamless integration and optimal performance when using Di2 electronic shifting components on your bike.
