CYCLUS TOOLS snap.in bottom bracket tool compatible with SHIMANO Dura Ace BB-7700 Z6 41.0 mm. Ideal for installing and removing the lock nut, for example for: Miche track hub lock ring, Continental 48V Revolution, Shimano Octalink Dura Ace BB-7700 and BB-7710.

To ensure the correct operation of the tool, it is also necessary to use the holder (item code: 7202750 or 7202749) and, if necessary, additional components such as an adapter or a guide. We recommend using the snap.in threaded guide (item code: 7202772). This combination of holder, extractor, and appropriate guide enables professional and correct installation and removal of the bottom bracket, without slipping or jamming. An additional advantage is that this guide can also be used with other tools from the snap.in family. Please observe the tightening torque specified by the manufacturer for each bottom bracket installation.
