Techniktipps zu Sturmey-Archer Nabenschaltungen: Unterschied zwischen den Versionen

===Installation und Einstellen===

The fine adjustment of the cable pull is accomplished by how far the sleeve at the end of the cable screws onto the threaded stud at the end of the indicator spindle's chain. The official manuals tell you to adjust it by visual examination of the end of the indicator spindle shaft, but this doesn't always work, especially if the indicator spindle is not original equipment. For best results, adjust the cable by tension. When the trigger is in high-gear position, the cable should be totally slack. Shift down to middle gear, while watching the indicator chain-it should clearly move as you make the shift. Then shift to low gear; again, you should see more chain coming out of the axle nut. Sometimes the internal parts line up in such a way as to prevent downshifting. If you have trouble getting the hub to downshift, turn the pedals slightly forwards. Once you are sure that the hub is in low gear, take hold of the indicator-spindle chain and try to pull more of it out of the axle. If the adjustment is correct, you should be able to get just a tiny bit more movement from the chain. If it is completely taut, the cable is too tight. Make sure to tighten the knurled locknut on the indicator spindle so that the adjustment will stay as you have set it. On a newer hub with more than three speeds, check for correct engagement in every gear.

If you hold the trigger halfway between middle and high gear with an older hub, it will disengage so that you can spin the pedals forward without going anywhere. If it freewheels forward in high gear, the cable is to tight or has too much friction to release properly. If it freewheels forward in middle gear, the cable is too loose. Be sure you keep the cable correctly adjusted. If the hub pops out of gear, especially when you are standing to pedal, you could crash, or bang a knee on the handlebar.
