Abstract: A chuck for inflating a tire having a Presta valve includes a valve engagement device defining an aperture with a central axis and a diameter, the valve engagement device movable radially with respect to the central axis to increase and decrease the diameter of the aperture. A locking device can engage with the valve engagement device to lock the valve engagement device in a selected radial position with respect to the central axis of the aperture. The chuck can include a seal positioned within the valve engagement device, the entire seal moving radially with the valve engagement device.

Abstract: A method and tool provide for removal of a rear bicycle wheel of a bicycle having a wheel with an axle mounted cassette of cogs. The tool includes a chain disengagement element movable with respect to an axle mounted cassette, wherein moving the chain disengagement element moves a portion of the chain away from the axle mounted cassette sufficiently to completely disengage the chain from the axle mounted cassette. This allows for easy removal of the wheel.
