One of the things we've always liked about our CyclePump, is the solid brass locking air-chuck. It's one of the easiest and most secure air-chucks on the market. This is just one more reason why the CyclePump excels in its design and function. However, some folks report a difficult time getting a good airtight connection between the chuck and the valve stem. This is caused because the air hose is coming in from an odd angle, usually due to large brake rotors and/or spokes and/or panniers getting in the way. The hose gets kinked or slightly off-center, and the air chuck can't make a good airtight seal. Or, on some bikes, there's just not enough room between the valve stem and the hub for an air chuck and hose to fit. (what were the designers thinking?) That problem's solved with these chrome plated 90-degree valve stem extensions. Simply remove the valve cap, screw the extension in place on the end of the stem, then make a straight-on-sideways connection with the CyclePump (or EZ-Air gauge). Fill the tire to the desired pressure, disconnect the CyclePump, then unscrew and remove the extension. Replace the valve cap and you're ready to ride. (Photo at left shows the valve stem extension - the camera perspective makes it appear to be 45-degrees, but it is a true 90-degree right angle) *Note: These extensions are only meant to be used while inflating the tire, they should not remain on the tire. If you leave the extension on the tire it will cause an unbalanced condition, it may damage the valve stem, and it may cause sudden loss of tire pressure
