Product information "Comp Bottom Bracket Key for Hollowtech II / Center-Lock Locking Ring external"

This Radon bottom bracket wrench is designed for the installation and removal of Hollowtech II bottom brackets, but also for mounting and dismounting of Center-Lock locking rings with external gearing.

Radon equips your bike workshop

Mile eaters can't avoid it: At some point the bottom bracket has to be replaced. It has the important task of guiding the bottom bracket spindle. A bottom bracket always consists of at least two bearings, which support the spindle on both sides of the bottom bracket casing. Radon offers reliable tools in this special area, especially for Press-Fit bottom brackets, but also for other standards.

Le 3 stelle sono per la descizione fuorviante. Non è adatto al 100% per centerlock, è smussato e non perfettamente piano all'attacco, la rondella centerlock è sottile e scivola... facendo molta attenzione si può usare per svitare ma, se lo usi per avvitare, anche cercando di tenerlo quando più dritto possibile, rischi solo di rovinare la rondella center lock che richiede 40 nm e questa chiave scivola molto prima

Robust and reliable, secure grip on external lockrings. Does the job! But delivered in different grip colour (black).

Der Schlüssel passt für das Moquai-Lager und vermutlich auch für viele andere. Leider ist man offensichtlich gezwungen, für den Ausbau eines Shimano-Lagers mit kleinen Lagerschalen einen Shimano-Schlüssel zu verwenden, denn der Kunststoffadapter von Shimano passt nicht in den Radon-Schlüssel. Allerdings passte der Adapter beim Einbau des Shimano-Lagers auch schon nicht gut in einen Shimano-Schlüssel, den ich mir geliehen hatte. Nun musste ich mir mit einer Rohrzange helfen, was angesichts des defekten Lagers ziemlich wumpe war. Aber ein Wechsel, bei dem das alte Lager für eine Weiterverwendung bestimmt ist, ist so nicht möglich.
