Find axle Length

Locate your shoe size in the table. Determine your foot position. Cross-reference both values to find your optimal axle length.
The SQlab 521 City Pedal is designed for urban use and supports a natural foot position for more comfort in everyday life. The individual axle lengths ensure a physiological position of the feet, reduce one-sided stress, and can alleviate discomfort such as the fibular head syndrome. For smaller shoe sizes or a shorter sit bone distance, the variant with a shorter axle is available – to reduce the Q-factor and for a precise fit. Four available axle lengths enable precise adaptation to individual body geometry.

Key Features:
Four axle lengths for biomechanically optimal adjustment
Extended axle to promote a physiological foot position
Reduced Q-factor with shorter axle length – ideal for small shoe sizes or narrow sit bone distance
Relieves knees and fibular head through natural pedal position
