    About

    Since 1974, we've had one goal: Innovate and inspire to improve riders' lives.

    Innovation

    Innovate or Die. Three words behind every design decision we make.

    Stories

    Bikes are part of a greater culture with tremendous stories. This is where you'll find them.

    Sustainability

    We recognize that the decisions we make have social and environmental impacts and that we are responsible for minimizing them.

    Retül

    Helping riders make data-driven decisions to improve the ride.

    Outride

    The Specialized Foundation uses cycling as a tool for children to achieve academic, health, and social success.
