Thunder

Thunder: A loud crashing heard after lightning, caused by the expansion of rapidly heated air.

The trail get's no — "heads up!" By the time you hear it, the strike has already occurred. When you're blasting down a new stretch of single track, the sound is deafening. The only noise exists in the moment — your bike, the environment, and you. If you're tired of hearing a bunch of static nonsense, and need to turn the volume down before you crack, then listen up.
