These spoke / drive clamps for the Autohelm 4000 and ST4000 are available in all sizes (the most popular being sizes B - 1/2" / 12mm and C - 5/8" / 16 mm). All of the different size clamps are available on our Shapeways Store.
These are printed in high strength Nylon PA12 - stronger than any other type of 3D printing you will find being sold elsewhere. These are stronger than the original Autohelm clamps - solid plastic, not hollowed out like the originals.
Please select the size of spoke clamp you need. The size refers to the diameter of the spoke tube, equal to the inside diameter of the clamp. There is usually a letter (A,B,C,D,E,F) stamped under the arch of the clamp which indicates its size.
NOTE: Price is for 1 spoke clamp
