The 14 mm bicycle crank wrench is a specialised maintenance tool designed for loosening and tightening 14 mm hex crank bolts.
Key Features
Construction and Design
The wrench is made from durable metal and features a deep 14 mm socket for reaching the fixing bolt located in the centre of the crank arm. Its extended handle provides improved leverage during maintenance work.
Main Functions
The tool is used to remove crank fixing bolts before fitting a crank puller. It can also be used to tighten compatible bolts when installing crank arms onto the bottom bracket spindle.
Use and Compatibility
The wrench is suitable for many three-piece cranksets that use a 14 mm hex fixing bolt. The bolt size should be checked before use, as some cranksets require an 8 mm hex key or a different fastening system.
Additional Features
Its compact design makes the tool easy to store in a home workshop or bicycle tool box. A compatible crank puller is usually required in addition to this wrench to remove the crank arm completely from the spindle.
Summary
The 14 mm bicycle crank wrench is intended for cyclists and mechanics carrying out crank installation or removal. Its durable construction and deep socket provide convenient access to the crank fixing bolt.
