Octalink / ISIS Crank Installation and Removal Tool
The Octalink / ISIS crank installation and removal tool is a dedicated bicycle maintenance tool designed for removing crank arms from square-taper, Shimano Octalink and ISIS bottom bracket spindles.
Key Features
Its versatile construction allows it to be used with several common crank systems, making it suitable for home maintenance and workshop repairs. The tool is operated with a 16 mm open-ended or adjustable spanner.
Construction and Design
The tool is made from durable chrome vanadium steel to withstand the mechanical force generated during crank removal. Its compact design makes it easy to store in a bicycle tool kit.
Main Functions
The threaded body screws into the crank arm, while the central bolt is tightened to gradually press the crank away from the spindle. An additional tip allows the tool to work with the wider spindles used by Octalink and ISIS systems.
Use and Compatibility
The tool is compatible with crank arms fitted to square-taper, Shimano Octalink and ISIS bottom bracket systems. The outer thread should always be fully inserted into the crank arm before applying pressure to avoid damaging the crank threads.
Additional Features
The opposite end may be used to loosen 14 mm crank fixing nuts or bolts. Its straightforward mechanical construction requires little maintenance and is suitable for repeated use.
Summary
This Octalink / ISIS crank tool is intended for cyclists and mechanics servicing drivetrains or replacing cranksets and bottom brackets. Its main advantages are broad compatibility, durable steel construction and simple operation.
