Review on Joyway Inflator Valve Connector Stainless by Donald Cummings

This air sleeve attaches securely to the air restrictor on my Trek bike's rear shock and releases quickly enough to prevent the pressure from dropping after inflation. The air pump I bought came with a cartridge that was too big and bulky for the job and it solved both problems at once. I used this to modify the extension hose instead of cutting the two valve heads off the pump hose as this head would also bleed my presta valves.
