The perfect saddle starts with an imprint of your butt

0The saddle is arguably the most critical and frustrating contact point on a bicycle. For decades, the industry standard has been "trial and error"—buying off-the-shelf shapes and hoping your anatomy conforms to the plastic. In this video, we explore a technical shift: Additive Manufacturing (3D Printing) driven by biometric data. We take a deep dive into the Posedla "Joyseat" process, moving from the analog (the "Smiling Butt" foam impression) to the digital (flexibility and mobility data), and finally to the physical (a custom-mapped carbon lattice). This isn't just about a new seat; it’s about a closed-loop system designed to remove the guesswork from bike fitting. In this technical look, we cover: The Input: How the "Smiling Butt" kit captures sit-bone geometry and pelvic tilt. The Translation: Turning personal mobility and riding style into a 3D-printable file. The Output: A first look at the Joyseat 3.0—why a T-shaped design and a bespoke lattice change the ride feel. The Field Test: Taking the custom build on a 140km "all-road" test from Kendal to Lockerbie in typical British conditions. The Result: Why 3D printed saddles handle water better than traditional foam and the long-term "one-and-done" investment. Is the future of cycling comfort found in a printer? We’re keen to hear your thoughts on custom-mapped tech in the comments. #Mapdec #3DPrinting #BikeFitting #CyclingTech #Posedla #BespokeCycling 📍 Video Chapters (Timestamps) 00:00 The "Smiling Butt" Kit: Capturing the Data 00:44 The Digital Questionnaire & Mobility Tests 01:35 Making the Impression: The Process 03:22 Setting the Baseline: Current Saddle Geometry 04:46 Measuring Flexibility & Hamstring Tension 06:10 Custom Branding & Aesthetic Choices 07:03 Tricking the System?
