Fietsen Crank Shortener

A simple solution that can make a big difference — the Fietsen op Maat Crank Shortener helps riders overcome leg length differences, limited joint mobility, and pedal reach challenges without replacing their existing crankset.

The Fietsen op Maat Crank Shortener is an adjustable cycling aid designed to reduce the effective crank length on one side of a bicycle. By shortening the pedal circle, it helps compensate for leg length discrepancies, limited knee or hip flexion, prosthetic use, or situations where a rider struggles to comfortably reach the pedals. Rather than requiring a new crankset, the unit mounts directly onto the existing crank arm and allows the pedal position to be adjusted to suit the rider's individual needs.

Manufactured from high-quality aluminium, the crank shortener is fully adjustable and compatible with most bicycle and e-bike crank arms up to 40mm wide. Its universal design allows installation on either the left or right side, making it a versatile solution for adaptive cycling, rehabilitation, and comfort-focused riding. The adjustable design allows riders and bike fitters to fine-tune pedal positioning for improved comfort, smoother pedalling, and greater confidence on the bike.
