Trek Adds Their First 3D Printed Saddle, Aeolus AirLoom RSL Saddle Tested

September 11, 2025

Trek has just released its first 3D printed saddle, and it was worth the wait. The new design comes as an update to Trek’s aero-all-around Aeolus saddle range, now featuring AirLoom lattice technology. The new AirLoom (pretty cool name) is a 3D-printed structure designed to provide targeted sit-bone support and pressure relief under soft tissue. Bike Rumor!
