Bicycle 3D Printed Saddle Ultralight Carbon Fiber Road Mountain Bike Seat Cushion Hollow Comfortable 3D MTB Saddle Seat

The reviewer discusses their experience with a cheap 3D printed saddle purchased from AliExpress for about $70. They have used it for approximately a year and a half, covering around 6,000 miles, primarily on indoor training rides. The saddle has dimensions of 240 mm in length and 143 mm in width, with 7x9 carbon rails and a weight of about 199 g. The reviewer notes that the cushioning, especially in the sitbone area, has softened over time, making it less optimal for rides longer than 2 hours. Despite this, they still recommend the saddle due to its affordability and durability, suggesting that it offers good value for the price. They also mention that the saddle has survived two indoor winter seasons on Zwift, including long endurance rides. However, they have since switched to a narrower saddle (130 mm) due to changes in their bike fit.

The reviewer briefly mentions a 'knockoff 3D printed saddle' as part of the bike's components, noting its presence but not providing extensive details. They express uncertainty about whether it's truly a knockoff or an original product, given the prevalence of imported bike parts. The saddle is part of a custom-built open mold bicycle that the reviewer finds impressive overall, though the focus of the video is not specifically on the saddle.

The reviewer discusses their experience with a 3D printed saddle purchased from AliExpress for $68. They highlight its comfort, lightweight design, and value for money. The saddle features a carbon shell, 7x9 carbon rails, and a honeycomb pattern for pressure relief. The reviewer compares it favorably to more expensive options like the S Works Mirror saddle, noting its similar comfort at a fraction of the price. They mention setting it up was easy, though tightening the bolt was slightly tricky due to the honeycomb design. The reviewer plans to purchase more of these saddles for other bikes.

The reviewer compares a $68 bootleg 3D printed saddle to a $450 original, noting their similarities and differences. They mention that the bootleg is slightly lighter (197g vs 202g) and looks very similar to the original, with carbon bottoms and rails. However, the bootleg lacks the density changes and specialized body geometry of the original, making it uniformly firm. Despite this, the reviewer is pleasantly surprised by the bootleg's comfort and states they would keep it in rotation, though the original is slightly more comfortable due to its research and technology.
