I have presta valves on my bicycle tires. This morning went to put some air in the rear. When I removed the adapter, it took the core of the valve stem out with it. The little brass stem went rocketing across the garage and hit the back wall, scary projectile. Heard it, couldn’t see it. Tire deflated in two seconds flat, no pun intended. Walked to work. Over lunch discovered that the one bike shop within walking distance of UC Berkeley has closed down.
