The Nexus 8-speed hubs have a overlocknut spacing ranging of 132 to 135 mm, as sold: see Shimano's overlocknut spacing chart. It is possible to reduce the spacing of the Nexus Rollerbrake/freewheeling models to as little as 126 mm by leaving off the Rollerbrake and using a narrower locknut. See our Rollerbrake page for instructions. This is not possible with the coaster-brake or disc-brake models Including the Alfine.
Die Nexus Achtgang-Naben haben normalerweise ab Werk einen [[Mutternabstand]] von 132 bis 135 mm. Siehe auch [https://web.archive.org/web/20130925001938/http://www.shimano.com/publish/content/global_cycle/en/us/index/tech_support/tech_tips.download.-Par50lparsys-0015-downloadFile.html/08%29%20Hub%20Dimensions.pdf Shimanos Mutternabstanstabelle für Nexus Naben]. Man kann diesen Abstand beim Nexus Rollerbrake/Freilauf-Modell auf 126mm reduzieren, indem man die [[Rollerbrake]] weglässt und dünnere [[Kontermutter]]n einsetzt. Dazu findet man mehr im Artikel [Das 1x1 der Shimano Rollerbrake]]. das funktioniert nicht bei den [[Rücktrittbremse]]n- oder [[Scheibenbremse]]nmodellen und auch nicht bei den Alfine Naben.


The internal mechanism of these hubs is complicated, and the usual repair is to replace the mechanism in its entirety. Shimano indicates little compatibility with hub shells of different models -- see the last two pages of this document -- but the internal mechanism can usually be replaced with a newer version as long as the hub is in the same series (with or without coaster brake; same number of roller clutches -- also be aware of other differences which may affect the design of the shell). See this Shimano document for description of some internal differences. You'll find details about interchangeability if you keep reading this page...

There is some interchangeability between Alfine and Nexus models. When a model number in the interchangeability column is in italics, the entire internal assembly is compatible.
