Park Tool VC-1 Valve Core Tool Works on Presta Schrader Valve Extender

Recently I broke a presta valve when pumping my tire out on a ride. Though pricey compared to the competition it is well finished easy to use and very lightweight. It was a good feeling to know I had this in my tool kit along with a spare valve. Might be good to have a 3/8" socket or adjustable wrench just in case you have a stubborn valve. Unfortunately I found out that not all presta valves are replaceable. In the description there is a warning to that effect but did not notice this. For the most effective use of this product probably good check your bike. You might have to replace the tube to use this.;

Excellent tool works perfectly it's build with sturdy materials and easy to use;

Park Tool has done it again! Another beautiful little tool that does what it’s supposed to do. The Snap-on of bike tools without the stupid price.;
