Es gibt eine [https://www.sheldonbrown.com/Disassembly%20of%20SRAM%20i-9.pdf Dokumentation von John Allen zur Demontage der i-Motion 9 Nabe (PDF/englisch)] Die Nabe ist recht komplex im Aufbau, jedoch sollte ein versierter Mechaniker die Anleitung verstehen können und auch die rückwärts ablaufenden Schritte ausführen können, um die Nabe aus den Einzelteilen wieder zusammenzusetzen. Das ist anders als bei den früheren [[Elan 12 Gang Getriebenabe]], deren Achsaufbau nur mit Fabrikwerkzeugen wieder zusammenbauen ließ.


I have documented disassembly of the disc-brake/brakeless version of this hub (PDF file). The hub is rather complicated, but an accomplished mechanic should be able to read the instructions in reverse and reassemble the hub from individual internal parts -- unlike the earlier 12-speed Elan hub, whose axle assembly was only rebuildable with factory tooling.


There are a couple of hitches, though: SRAM doesn't supply individual replacement parts. The gear unit was only ever sold as a single part, and SRAM does not stock replacement parts for its internal-gear hubs in the USA. Also, an internal nut is destroyed in disassembly and is not available for replacement. Aaron's Bicycle Repair in Seattle, Washington, USA has had replacement nuts fabricated and sells them. Aaron is assembling a stock of spare parts and can rebuild these hubs.
