Columbia with tube frame: The original valve on a Columbia Commuter (tube frame) was a vertical mount valve, mounted in the sideways position. So the valve faces up, instead of sideways. That is not bad, but the poor handle gets kicked easily since it is right where you step through the frame at. The original valve had a reserve tube that curved upward, like on a Puch side mount. The replacement valve has a short straight reserve tube. Sideways installation disables the reserve feature. Optionally, a longer curved soft aluminum reserve tube is available. See below.
