Trek has introduced its first 3D-printed saddle series, the Aeolus AirLoom, featuring what the company calls AirLoom lattice technology. The new design updates Trek’s existing Aeolus saddle range with a 3D-printed structure intended to provide targeted sit-bone support and pressure relief. The saddles have already undergone testing at WorldTour cycling events and mountain bike World Cups.
The AirLoom lattice uses a truncated-octahedron structure that replaces traditional foam padding. According to Trek, this lattice design flexes and rebounds consistently while distributing pressure across sit bones and maintaining an open perineal channel. The company states this approach differs from foam, which can compress unevenly and degrade over time.
Trek has also modified the saddle’s shape, narrowing the nose to reduce thigh contact and adding a longer slope designed for riders in aggressive, aerodynamic positions. The updated transition between the nose and wings represents a departure from the previous Aeolus design.
The AirLoom line includes four models at different price points. The top-tier Aeolus RSL AirLoom features an OCLV carbon shell and oversized carbon rails, weighing 166g and priced at $424.99. The Pro model costs $274.99 with carbon rails and composite shell at 180g, while the Elite AirLoom uses steel rails and nylon shell for $174.99 at 242g. Trek also offers a traditional foam version, the Aeolus Elite, for $99.99 weighing 267g.
