==Hybridschaltung==
 
Eine [[Hybridschaltung]] nutzt eine Nabenschaltung in Kombination mit einer Kettenschaltung. Sturmey-Archer und [[SRAM]] haben Drei-Gang-Naben im Programm, die Rippen für Acht-, Neun- oder Zehn-Fach-Kassetten haben. Die Naben sind insbesondere nützlich bei Fahrrädern, an denen man keinen [[Umwerfer]] montieren kann oder die sehr kleine Laufräder haben und man durch den Einsatz der Hybridschaltung und ihre sehr hohe Übersetzung im höchsten Gang kein wirklich großes Kettenblatt benötigt.
Hybrid gearing uses an internal-gear hub along with derailer gearing. Sturmey-Archer and SRAM make 3-speed hubs with splines for an 8- 9- or 10-sprocket cassette. These hubs are especially useful on bicycles which can't take a front derailer, and on small-wheel bicycles, where the hub's step-up top gear makes an oversized chainwheel unnecessary.


The stock cassettes sold with SRAM hybrid-gearing systems work OK, but I like other combinations better. The stock Shimano CS‑HG50‑8 8-speed cassette, 11-13-15-17-19-21-24-28, works well with a small wheel. On the older Sachs 3x7 system with the short 7-speed cassette body, the Shimano M cassette, 13-15-17-19-21-24-28, or the D or F cassette, 14-16-18-21-24-28-32 is good, or an 8 of 9 on 7 leaving off the smallest sprocket of a stock Shimano XT or XTR cassette -- 12-14-16-18-21-24-28-32. To use the 8 of 9-speed combinations, you need an 9-speed chain and an 9-speed shifter (or 8-speed shifter with alternate cable routing). It is also possible to build up a custom combination. Good 9-speed custom combinations are 13-15-17-19-21-23-25-28-32 and 11-13-15-17-19-21-24-28-32.
