The RocStem It offers a wealth of settings and enables a driving experience that is not only individually tailored to your needs, but also offers maximum comfort and improved control - without having to compromise on safety.
Frequent loosening of the side clamp bolts on a stem is not recommended. Why? Although the bolts are made of steel, the stem threads are aluminum. Repeated loosening inevitably leads to wear, which weakens the threaded connection. This connection is not designed for such stress. Furthermore, there is a risk that the top cap will detach from the steerer tube when the entire stem is rotated. This is extremely problematic, as the headset preload is adjusted via this cap! Incorrect headset preload adjustment can damage not only the headset bearings or even the frame, but also lead to unsafe handling and even crashes.

This unique innovation not only saves valuable space but also enables effortless operation without affecting the original riding position.
