Report a Near-Miss Collision, Road Hazard or Unlawful Activity: (916) 358-0333 

Bicycle Descending Technique for Mount Diablo! We have been observing how cyclists descend around the 300 curves on the mountain. The majority of cyclists are putting themselves in danger (red path below) without knowing it. We analyzed 30 Bike vs Vehicle Collisions (2010-2017) and reviewed numerous Near-Miss Bike vs. Vehicle Collision videos. In addition, we spoke to collision victims and cycling experts. Please consider practicing this descending technique! Please share it with your cycling friends and cycling groups who plan to ride Mount Diablo! Special Thanks to Linda, Avery and Carl for their help creating this amazing poster!
