Digital Sitbone Device

The Digital Sitbone Device, or DSD, takes the guesswork out of choosing the correct saddle to make long days on the bike more comfortable. With the use of hundreds of sensors, the DSD gives real-time pressure feedback to accurately measure your sit bone width. Based on these measurements and your preferred riding experience, the DSD provides you with personalized saddle recommendations. 

Digital Footbed Device

The Digital Footbed Device, or DFD, takes a pressure map of your arch height and uses hundreds of data points to determine which level of Body Geometry SL footbeds or custom footbeds would help make you comfortable on your ride. 


All your DSD and DFD data is stored in your Retül Passport profile to provide easy access to your results and product recommendations at any time.
