About
Retül is a cutting-edge bike fitting and product matching platform developed to help cyclists of all levels achieve peak efficiency and comfort through data-driven personalization. At its core, Retül captures precise biomechanical data during a cycling session to analyze rider position, movement, and alignment — providing fitters and athletes with actionable insights to optimize their setup. The platform encompasses three main pillars: Retül Fit (a comprehensive bike fitting experience), Retül Footbeds (custom insole solutions to improve pedaling efficiency and foot stability), and Saddle Sizing (a data-informed process based on sitbone width measurements to match riders with the ideal saddle). Each offering is designed to reduce injury risk, improve power transfer, and enhance overall riding comfort. Retül is closely integrated with Specialized's Body Geometry product ecosystem, allowing fitters to directly match riders with compatible components. The technology is available through certified Retül fitters at select retailers around the world, making professional-grade fitting accessible to everyday cyclists. A member login portal gives users access to their personal fit data, enabling continuity across future fittings and equipment changes. Ideal for competitive cyclists, triathletes, recreational riders, and bike shop professionals, Retül turns complex biomechanical analysis into clear, personalized recommendations — making the connection between rider and machine more precise than ever.
