Einstellen der Schaltung: Unterschied zwischen den Versionen

===Alternative Zugführung===

Shimano originally publicized an alternate cable routing which placed the cable slightly closer to the pivot, making the derailer move slightly farther for each click. This adaptation makes newer Shimano derailers work with older Dura-Ace shifters, but it is also useful when you want to use a 9-speed cassette with 10 speed shifters, or 8-speed cassette with 9-speed shifters, or a 7-speed cluster with 8-speed shifters. You may need to fine-tune the amount the cable deviates from the standard position, so the derailer sweep matches the sprocket spacing.

The other alternate cable routing, suggested by Brian Jenks, proprietor of Hubbub Cycles, decreases the derailer travel for each click. This makes some Shimano derailers and shifters compatible with Campagnolo cassettes. It is also useful when you want to use a 10-speed cassette with 9-speed shifters, or 9-speed cassette with 8-speed shifters, or an 8-speed cassette with 7-speed shifters. You will then lose the use of one sprocket, unless you are using a shortened cassette such as an 8 of 9 on 7, or 9 of 10 on 7. Note the two tabbed washers in the drawing below -- one to change the cable routing, and the other to secure the cable. Again, you may need to fine-tune the cable position.

Unlike the Dura-Ace modification, the Hubbub modification is nonstandard, and not all of the ratio changes are accurate. Chris Juden of the Cyclist Touring Club (U.K.) has posted a Web page listing usable combinations. Pulley-type adapters from JTek Engineering offer a more precise alternative.
