Estrattore per cassetta pignoni bici FISCHER 85523 – estrattore per cassetta compatibile con diverse cassette

FISCHER Bike Cassette Puller 85523 is a manual tool designed to remove and install bicycle rear cassettes. The tool engages the cassette splines to provide a secure connection for loosening or tightening the lockring and sliding cogs off the freehub body. Intended for home maintenance and workshop use, it supports routine drivetrain servicing, cassette replacement and repair tasks on compatible cassette systems.

Advantages

The cassette puller offers a precise spline fit and solid engagement with cassette lockrings to reduce slippage during removal. Its manual, compact design requires no power source and is easy to store in a toolbox. Built for compatibility with a range of cassette types, the tool enables controlled application of torque when used together with a compatible wrench or breaker bar. The simple construction minimizes maintenance and ensures repeatable performance for periodic cassette servicing.

Suitable for

• Home bicycle maintenance and do-it-yourself cassette replacement
• Workshop use for repairs and drivetrain servicing
• Removing and installing cassettes during wheel or hub servicing
• Mechanics needing a compact, manual cassette removal solution

Key specifications

• Type: Manual cassette removal tool for rear cassettes
• Compatibility: Fits a range of cassette spline patterns and lockrings (check compatibility with specific cassette models)
• Material: Durable metal construction for torque transfer and longevity
• Drive interface: Compatible with standard wrench or breaker bar for applied torque
• Size/Weight: Compact, lightweight design suitable for toolbox storage

How to use

Position the cassette puller so its splined interface fully engages the cassette lockring. Secure the tool against the cassette and fit a compatible wrench or breaker bar onto the tool's drive interface. Hold the wheel or axle steady while applying controlled torque to loosen the lockring in the correct direction. Once the lockring is removed, slide the cassette sprockets off the freehub body. For installation, reverse the steps: place sprockets on the freehub, engage the lockring with the tool and tighten to the manufacturer's torque specification.

Recommendations

Inspect the cassette splines and lockring for damage before use and clean mating surfaces to ensure proper engagement. Use a torque wrench or follow manufacturer torque guidance when tightening lockrings to avoid over- or under-tightening. Wear appropriate hand protection when applying force and store the tool in a dry place to prevent corrosion.
