If the Rotundo shape is a little too aggressive for you, the Ergo Sum is the answer. Unlike standard anatomic bars, the Ergo Sum bar offers a smooth continuous bend to keep the hand comfortable no matter where in the drops you grip. Of particular note is the revolutionary quick bend upper curve feature where you mount your shift/brake lever. thanks to the very tight curvature, the rider can adjust the orientation of the lever over a wide range of angels without having to move the lever far down the drop as is usually required. Rotation without translation
- a small, simple idea.
