CYCLUS TOOLS snap.in bottom bracket tool SHIMANO Octalink Z20 32.0 mm. Ideal for installing and removing the bottom bracket, for example for:

• Kinex square aluminum


• Shimano BB-UN 51, 71, 72


• Shimano Compact


• Tecora aluminum


• Truvativ BB Power Spline


• Shimano BB-UN 51/71/72 (threaded guide item no.: 7202770)


• Tecora aluminum (threaded guide item no.: 7202770)


• Shimano Octalink BB-7700/6500/5500 (guide screw item no.: 7202772)

To ensure the correct operation of the tool, it is also necessary to use the support (item no.: 7202750 or 7202749) and, if necessary, additional components such as an adapter or a guide. The use of the snap-in threaded guide (item no.: 7202770) or the threaded guide (item no.: 7202772) is recommended. This combination of support, extractor, and appropriate guide allows the internal bearing to be installed and removed professionally and correctly, 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 installation of the internal bearing.
