Handlebar center diameter

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

Stem angle

The angle of a cycling stem, often called 'rise,' impacts your riding position. A stem with a 0º angle is perpendicular to the steerer tube. Positive angles, like +6º, raise your handlebar, creating a more upright position. In contrast, a double-angled stem or flipping the stem creates a negative angle, making your upper body flatter and more aerodynamic. Our range includes stems with varying degrees of rise, from zero to -40º to +60º. It's essential to test different stems for the best fit or consult your local bike shop or get a bike fit for personalized advice.
