Your Hammerhead Heart Rate Monitor features an adjustable and washable elastic strap with an easily detachable sensor pod. We recommend removing the sensor pod from your strap after each ride for cleaning and storage. The salt in sweat can degrade the strap materials over time, so washing is even more important after indoor training sessions or hot summer rides. We recommend handwashing with gentle soap in your post-ride shower or in the sink. The strap is also machine washable, but handwashing will prolong its lifespan.
