Bike Fit Fundamentals: https://roadcyclingacademy.com/bike-fit-fundamentals/
Bike-fit expert Neill Stanbury puts three budget 3D-printed options to the test and explains who they suit β comparing shapes, cut-outs, carbon rails, durability, and comfort. Not sponsored.
What we cover:
AliExpress saddles vs premium (3D printed TPU, carbon rails 7Γ9)
Riot Air Code (Pro Stealth-style): broad back, wide nose, deep cut-out β great for riders who rotate pelvis forward and need perineum pressure relief
Riot Ultimate: narrower platform for riders with narrow sit bones
MIX 5D: ultra-light, flexible shell, big rear rise β for very narrow sit bones (100 mm) and lots of inner-thigh clearance
Why fit first (saddle height, setback, reach, drop, cleats) often fixes βsaddle problemsβ
Cut-out vs no cut-out: when a channel is near-mandatory
How sit-bone width & wing taper reduce chafing and numbness
The reality: trial-and-error beats guessing β how to test smarter

SaddleMIXED Full Carbon Fiber 5D Ultra Pack Light Weight Bike Saddle 143mm 135g for Road MTB Mountain Bicycle Carbon Seats
Created: March 07, 2025The reviewer discusses the MIXED 5D saddle as one of three AliExpress saddles they use in their clinic. They describe it as extremely light and specifically recommend it for people with incredibly narrow pelvises and sitbone dimensions under 100mm. The saddle features a very flexible carbon shell, a massive rise at the rear, and tremendous clearance on the wings, making it good for riders who rotate their pelvis forward. However, they note the padding is not as good as 3D printed alternatives and that it is a bit delicate, having snapped on the inside edge from bearing weight on the front.
