Shimano has recently expanded its Pro Stealth series with the introduction of a new saddle featuring a 3D-printed pad—the Pro Stealth 3D.

Without altering the series' signature short-nose geometry, this saddle leverages technological innovation to more precisely distribute the pressure riders experience in different positions.

According to the official description, the development of the Pro Stealth 3D was based on pressure mapping data from actual cycling tests and feedback from test riders. Its core is an additively manufactured lattice structure designed with three distinct density zones:

The front section uses a higher-density material to support riders when they adopt an aggressive, forward-leaning riding posture.

The middle section is relatively softer, designed to spread the load over a larger area when the rider is in a more upright position, effectively reducing localized point pressure.

The rear section has a lower density, as there is less contact during pedaling; this also helps to reduce overall weight.

The entire 3D-printed pad also employs a hexagonal cell geometry. According to the manufacturer, each individual cell can deform locally under load, thereby absorbing vibrations at specific points and throughout the structure. This aims to reduce the transmission of road bumps and alleviate fatigue on long rides. The cellular structure is clearly visible and is not covered by a traditional top layer. The pad is made of expanded polyurethane (EPU), and its textured surface helps maintain the rider's position during seated pedaling.

Regarding versions, the Pro Stealth 3D is available in a Team edition with carbon fiber rails and a Performance edition with INOX stainless steel rails. Both versions come in 142mm and 152mm width options. The claimed weights are approximately 224 grams for the Team edition and 260 grams for the Performance edition. At the time of writing, UK pricing has not yet been announced.
