Vision SMR ACR Stem

While the stem features a standard 31.8mm clamp diameter compatible with most bars, the internal cable routing system works best with handlebars designed to accommodate ACR or similar integrated routing paths. If your current bars do not have ports for internal routing, you will not be able to fully utilize the clean cockpit design.

Yes, it is designed to fit standard 1-1/8 inch (28.6mm) steerer tubes. However, because it is an integrated stem, ensure your headset and spacers are also compatible with the ACR routing system to maintain the intended aesthetic and functionality.

This stem is specifically engineered for road and gravel applications. While it is constructed from durable alloy, its geometry and internal routing focus are optimized for drop-bar setups rather than the wider, more aggressive handling requirements of mountain bikes.

Yes, the removable faceplate simplifies the installation and removal of your handlebars. It allows you to swap bars without having to strip your entire cockpit, though you will still need to manage the internally routed cables during the process.

The -6 degree angle is a standard road geometry that provides a slightly aggressive, aerodynamic position without being overly slammed. It offers a balanced feel that works well for both endurance riding and faster, performance-oriented gravel or road efforts.
