## Long description

The Okbaby ROL-3100 cassette wear gauge is a mechanical tool designed to assess wear on Rohloff HG-IG bicycle cassettes. It fits the HG-IG cassette tooth profile and provides a quick, repeatable check to determine whether sprockets have worn to the point of requiring replacement. The tool is compact and intended for use in workshops and at-home maintenance to help maintain drivetrain performance and reduce shifting problems caused by worn teeth.
Advantages
This wear gauge gives a consistent, simple measurement method specific to Rohloff HG-IG cassettes, allowing technicians and cyclists to identify worn sprockets without disassembly or complex measurement tools. The device speeds up inspections, supports preventative maintenance, and helps avoid the inefficiency and noise associated with worn cassette teeth. Its design promotes repeatable assessments so maintenance decisions are more reliable.
Suitable for
 Workshops performing routine drivetrain inspections and maintenance
 Home mechanics checking cassette wear before replacing sprockets or chain
 Bicycle shops evaluating used cassettes for resale or service
 Fleet maintenance for rental or commuter bike programs
Key specifications
 Compatibility: Rohloff HG-IG cassette tooth profile
 Function: Mechanical wear gauge for sprocket/tooth wear assessment
 Measurement approach: Pass/fail or wear threshold check with repeatable positioning
 Form factor: Handheld, compact inspection tool suitable for bench or field use
 Material: Durable construction appropriate for workshop use
How to use
Position the gauge on each sprocket in turn so that the tool engages the tooth profile according to the manufacturer’s alignment features. Observe whether the gauge seats correctly or indicates excessive clearance/wear; a proper fit indicates acceptable tooth geometry while failure to seat or noticeable play indicates worn teeth. Repeat the check across all sprockets to identify individual worn cogs and to decide whether cassette or chain replacement is necessary. Clean the cassette of dirt and grease before measurement for reliable results.
Usage recommendations
Use the gauge after regular chain maintenance and following a defined mileage interval or when shifting performance deteriorates. Combine gauge checks with chain wear measurement for more accurate maintenance decisions. Store the tool in a dry place and keep contact surfaces free of debris to preserve measurement accuracy.
