The Handles

The following drawings have been taken from some rather indistinct originals, but hopefully the details are clear enough.

Some of the dimensions in the 2 different drawings of each handle appear to contradict each other. I do not know which is correct, but I will try and measure some wheels and ammend the drawings if there is a clear error. If anyone can confirm or clarify the dimensions please let me know.

 

Materials

The handles are made from steel to specification DIN2458 ST 37.2

The tube has a diameter of 26.9 mm and a wall thickness of 2.6 mm
