Wolf Tooth Geoshift:

The angle-adjustable Geoshift headsets allow the head tube angle to be adjusted by 1 or 2 degrees, depending on the model. Such a modification can be particularly useful in mountain biking. A flatter angle provides greater stability on fast descents, whilst a steeper angle enhances steering response and ensures maximum front-wheel traction.
