The FIT System

What is Body Geometry FIT

Specialized Body Geometry Fit is the proprietary process developed by one of the leading bike companies in the world through Mike Sinyard and Andy Pruitt. The process takes fitting back to fundamentals with a rider centred approach. This is seen in the Fit session, with a significant duration allocated to rider discussion accompanied by pre-fit physical assessments on joint range of movement, stability and structure.

What is Retül FIT

Retul is a bike fit tool that layers on top of the BG Fit process. Key to understand however is that it does not instruct the fitter what to do or substitute for experience. What it does is capture data, in one of the most accurate and comprehensive ways available, providing a data driven and informed approach to the fit process. This gives the fitter one of the most powerful tools available, to enhance their abilities and provide you, the rider, the best fit available.

RETÜL Vantage 3D Advanced Motion Capture System

Retül bike fitting is recognised worldwide as a leader in bike fitting systems, delivering the rider improved comfort, power and efficiency whilst working to prevent injury.

The Retül process achieves this with accurate, real-time, 3D dynamic analysis:

  • Accurate. The Retül process is accurate to within less than a millimetre.
  • Real-time. The Retül hardware captures and displays the bio-mechanical position instantaneously. Adjustments are made dynamically with the rider in motion, with the effects felt and seen instantly.
  • 3D. The Retül hardware uses multiple sensors to triangulate the position of the riders anatomical markers, plotting them in 3 dimensional space. This reveals true compound angles and allows tracking of the knees and hips.
  • Dynamic. The Retül process incorporates the rider pedalling against resistance to reveal true bio-mechanics.
The Fitter

The fitter is at the heart of the process. Tools cannot replace experience or the ‘fitters eye’, and so they are the most valuable ‘component’ in your fitting experience. Only certified fitters are allowed to conduct Body Geometry / Retül Bike Fits. So, you know you’re receiving the highest level of quality and service.
