Specialized is expanding its Power saddle series with the S-Works Power EVO Mirror model. The new saddle is intended to offer more freedom of movement and comfort in various riding positions thanks to a revised design. The innovative 3D-printed mirror technology is designed to significantly reduce pressure in critical areas.

Specialised introduces the S-Works Power EVO Mirror presents a further development of its successful Power saddle. The new saddle is designed to give riders more freedom of movement on the bike while increasing comfort in different riding positions. To achieve this, Specialized has revised the proven design of the Power saddle and combined it with the innovative Mirror technology from the 3D printer.

Revised design for more flexibility

The S-Works Power EVO Mirror retains the compact length of 24 centimetres of its predecessor, but features a few key design changes. For example, the nose of the saddle has been made one centimetre wider to provide more support in a sporty riding position. At the same time, the shape of the wings has been adapted to reduce strain on the thigh muscles. Thanks to these changes, you should be able to move more freely on the saddle without having to accept any loss of comfort.

Innovative mirror technology for optimum pressure distribution

The centrepiece of the new S-Works Power EVO Mirror is the advanced mirror technology. This is a 3D-printed honeycomb structure made from liquid polymer, which is designed to enable precise tuning of comfort and support. According to Specialized, the current generation of Mirror technology consists of 47,000 struts and 21,000 nodes. This complex structure is designed to optimise pressure distribution and reduce pressure peaks. Compared to conventional foam saddles, the pressure on the ischium is said to have been reduced by 28.8 per cent and on the saddle nose by 34.1 per cent.

Invisible saddle cut-out for more comfort

Another new feature of the S-Works Power EVO Mirror is the so-called "invisible saddle cut-out". The edges of the cut-out have been removed, which should lead to an 18 per cent reduction in pressure around the centre of the saddle compared to the previous model.

Improved customisation options and sustainability

To ensure an optimal fit for different body types, Specialized offers the S-Works Power EVO Mirror in four different widths: 130, 143, 155 and 168 millimetres. The saddle also has two centimetre longer saddle rails, which should allow greater flexibility in positioning.

Sustainability is also said to have played a role in the development: According to the manufacturer, 40 per cent of the liquid polymer used for the mirror technology consists of bio-based materials. This should not only improve environmental compatibility, but also contribute to greater durability and lower moisture absorption.

Lightweight with carbon construction

The S-Works Power EVO Mirror is based on a flex-optimised carbon shell with 7x9-millimetre carbon seat stays, which enables a low weight of 221 grams in the 143-millimetre width.

Scientifically sound development

According to Specialized, the development of the S-Works Power EVO Mirror is based on extensive scientific research. In collaboration with medical experts, the company invested over 500 hours in the development and testing of the saddle. Various areas of use such as road, gravel, cross-country and trail were taken into account. The results of the pressure measurements and comfort tests were directly incorporated into the design of the saddle.
