The Crank Shortener with Angle Compensation makes it possible to freely adjust the length of the crank arms, e.g. for adults and children with legs of different lengths or restrictions in leg mobility. The pedals can be individually adjusted along the crank for different requirements, optimising rehabilitation, or allowing the crank length to grow with your child.
Hase Bikes have recently redesigned the Crank Shortener to incorporate an angle adjust that compensates for offset or angled cranks which enables it to be correctly aligned with the crank arms, making for a smoother pedalling motion. The new forged part not only looks better than before but is also more robust.
The Crank Shorteners are sold individually and are universal for right or left side.
