    What ANGi can do for you

    When we get a chance to ride, we take it. We escape. Sometimes that means going solo. Sometimes that means dashing off without telling friends and family where we’re headed. Trouble is, crashes happen, drivers don’t always see you, and sometimes, we simply pick the worst possible line down the sketchiest possible trail.

    Reality, in other words, happens, which is why we offer the only helmets equipped with both MIPS brain-protection systems and ANGi—an innovative sensor designed to add protection, before, during, and after a crash.

    Protection Before
    ANGi is a ride tracker. ANGi lets your emergency contacts know you’re heading out for a ride and, if you choose, to follow your ride in real time.

    Protection During
    ANGi is a crash detector. Wearing an ANGi-equipped helmet is like having a friend there making sure you’re okay.

    Protection After
    ANGi is a safety beacon. If you’re hurt, ANGi alerts your emergency contacts that you’ve crashed and sends them your location.

    ANGi is a patented, helmet-mounted sensor that measures the forces transmitted to your helmet during a crash, as well as the harmful rotational forces that occur during crashes when your helmet doesn’t actually impact the ground

    ...And This is How it Works
    It’s simple. Just pair ANGi with a smartphone equipped with our Ride Premium app. If ANGi detects a crash during a ride, it sends a countdown alert to your phone. If you’re hurt and unable to stop the countdown, the app transmits a text alert and your most recently uploaded GPS coordinates to your emergency contacts.

    Get on the Ride
    The Specialized Ride app makes finding rides and getting connected to your cycling community quick and easy. It even records your ride and performance data, syncs seamlessly with popular apps like STRAVA, and powers ANGi’s ability to connect you to help.
    It’s available for both iPhone (iOS 10 or later) and Android (7 and later). You get a free 1-year subscription to the Ride Premium app with the purchase of any ANGi-equipped Specialized helmet or ANGi aftermarket sensor.

    ANGi is the culmination of years of research and development, but it all started on a training ride that went wrong. One rider went to the hospital. Another rider asked himself what he could do to help make every trip a little bit safer. ANGi is the answer.
