2024 RYET 3D Printed Saddle Ultralight Hollow Comfortable Full Carbon MTB Road Racing Bike Cycling Seat Bicycle Cushion Parts

Regarding longevity, I have a Ryet Ultimate with 3D printed padding in use since end of 2024. It has about 8000 km of mileage. It's holding up well so far, it also survived a minor crash. I have the EVA padded Ultimate on another bike since last year with 2000 km or so of mileage. It's holding up well, too. So personally I can't complain!
