Innenlagermaße für Einpresslager (Tabelle)
Bei der 2011er Interbike Ausstellung, hat sich Calvin Jones von Park Tool entsetzt gezeigt über die rasante Vermehrung von neuen Innenlagermaßen. John Allen hat hier die alle bekannten Maße, die zu finden waren aufeglistet. Sie sind nach Innenmaß der Lagersitzgröße sortiert, damit man leichter Kompatibilitäten erkennen kann. Der Einsatz von Adaptern - beginnend mit den ehrwürdigen Ashtabula Systemen bis hin zu den neuesten High-End Systemen - erlaubt einen Einsatz verschiedenster Wellen. Phil Wood stellt Adapter für die meisten Einpressinnenlager her.
