Austauschbarkeit von Schaltketten bei Sturmey-Archer Nabenschaltungen: Unterschied zwischen den Versionen

Some spindles are thick, and are identified by through hash marks or Roman numerals. The effective length is from the base of the threads to the shoulder before the first link of chain (points of the green arrow in the image below).

Spindles for most newer hubs are thinner, as shown in the image below. Some hubs accept only thin spindles. Each model of these newer spindles has a different-colored painted mark, which may be on the rod, or on the chain. Check the color of the mark under sunlight, because the blue and purple colors can easily be confused under indoor lighting. The red arrow in the image indicates the length from the base of the threads to the mark. No matter where the mark is, the length which most affects compatibility is from the base of the threads to the shoulder, indicated by the green arrow.

When using an indicator with paint marks on the chain, it is a good idea to make a mechanical markon the chain and/or to photograph the indicator: the paint is often obscured by dirt or simply falls off.

The hole in the end of the axle is large enough for a thick spindle, but there is an internal part with a smaller-diameter opening. The red arrow in the image below points to that part in a cross-sectional drawing of the axle. The part presses against a compression spring. The spring, in turn, pushes the clutch inwards against the outwards pull of the indicator spindle.
