PRO Vibe Stem

Yes, this stem features a 31.8mm handlebar clamp diameter, which is the industry standard for most modern road and gravel handlebars.

Yes, the -17 degree angle is quite aggressive. It is designed to help you achieve a lower, more aerodynamic profile, making it a great choice for racers or riders looking to optimize their position for speed.

While the stem is specifically engineered with integrated cable routing for Shimano Di2 electronic shifting, it can certainly be used with mechanical groupsets. Just note that you won't be able to utilize the internal routing features for mechanical cables.

No, the integrated topcap is designed to provide a clean, streamlined aesthetic without compromising functionality. You can still easily access and adjust your headset tension as needed.

At 228g, this stem is competitive for a high-rigidity aluminum component. While you can find lighter carbon options, the use of 7075 aluminum and titanium hardware provides a superior balance of stiffness and durability for high-wattage efforts.

This stem is designed for a 35mm steerer tube clamp diameter. Please double-check your fork's steerer tube size, as many mountain bikes use a standard 28.6mm (1 1/8 inch) steerer, which would not be compatible with this specific model.
