One sided clipless pedal available in four different axis lengths. Conventional clipless pedals force the feet into a virtually parallel position. The longer axle of the SQlab 502 clipless pedal allows a physiologically natural foot position. This prevents one sided loads - especially with a calf leg head or fibula head syndrome. The version with shorter axle is suitable for riders with small shoe sizes and small sitbone distances. The so-called Q-factor can hereby be reduced.  Reflectors and cleats are included. The included cleats are SPD compatible.
