RYET Full Carbon 3D Printed Bicycle Saddle Wide 155/152mm 7*9 120g Bike Seating EVA Saddle Triathlon Road MTB Cycling Seat

The reviewer mentions the RYET 3D printed carbon bike saddle, noting that it is on their Trek Domane SL5 and was purchased with their own money over a year ago for $51.74. They have ridden 10,000-15,000 km on it and describe it as a decent improvement over the stock saddle. The saddle is very light at 165 g and significantly cheaper than Western brand equivalents. The 3D printed structure adapts under pressure and distributes weight evenly, which the reviewer agrees with, finding it very comfortable. They note that saddle comfort is personal but the design logic is sound and there is a lot of positive feedback from thousands of sales and high ratings.
