Review on 🚴 PRO BIKE TOOL Valve Core Tool - Presta and Schrader Valve Core Removal - Ideal for Mountain Bike, Road Bike, and Motorcycle Set-ups by Nick Beck

Does not slide vertically on the Presta valve. Using it horizontally will give you about 1/4 turn before the spokes get in the way. Now that the flat spot is in line with the spokes, you can't use the tool to continue. To make matters worse, when you re-tighten, the jaws should have moved apart a little and begin to rotate and pull around the valve core. Haven't tried it on a Schrader valve but this end seems to be the same size as the tool I have for them. I would like another review to be posted prior to my order, discussing the actual use of the product.
