Hase crank shortener with angle compensation

The crank shortener is a device designed to reduce the pedaling circle (the effect equivalent to having shorter cranks) without having to modify the original crank.

The new version of the shortener allows the angle to be adjusted to compensate for the angle or curvature of the crank.

This way it can be installed on connecting rods that are not completely straight.

This system makes the pedal protrude between 1 and 2 cm from its original position.

The cutter can be used either on the right or left side, as it has two threaded holes with reverse threads for the right and left pedals.
