Nivex rear endsAuthor Eric Sayliss
Since the Nivex quick release rear drop-out caused much interest at the Boot and Back, I thought you might like to put it in Classic Components with an explanation of how it worked.
Nivex made parts under licence for Super Champion. The rear end shown here is on a 1939 Oscar Egg frame.
The rear drop-out, with the round metal lip at 90 degrees to the frame and a slightly raised lip, was for the chain to be brought off the smallest sprocket by moving the gear-change lever on to a new extra position.
The wingnut was then undone which also loosened a short length of axle and when the wing nut on the other side was loosened the wheel dropped out of the frame with the chain held in a secure position ready to be 'changed' back onto the sprockets.
