The IceToolz 11B3 Shimano ISIS Drive BB Tool 20 Tooth is a precision-engineered bicycle drivetrain service tool designed for the removal and installation of compatible Shimano and ISIS Drive bottom brackets with a 20-tooth interface. Built for professional bicycle mechanics, workshop technicians, cycling teams, and experienced home mechanics, it provides the specialised engagement required for controlled and efficient bottom bracket servicing.

The defining feature of the IceToolz 11B3 is its 20-tooth interface, engineered to engage compatible bottom bracket splines accurately. Proper engagement helps distribute and transfer torque effectively during removal or installation, giving mechanics greater control when working with bottom brackets that may be securely tightened inside the bicycle frame.

Manufactured from high-strength Cr-Mo (Chromium-Molybdenum) Steel, the IceToolz 11B3 provides excellent rigidity and durability for demanding workshop applications. Bottom brackets are subjected to continuous pedalling loads and can become firmly secured after extended use, making robust tool construction particularly important during drivetrain servicing.

The IceToolz 11B3 is suitable for technical maintenance procedures including bottom bracket removal and installation, BB replacement, crankset servicing, drivetrain inspection, drivetrain cleaning, component upgrades, and complete bicycle overhauls. Its dedicated design provides mechanics with a purpose-built alternative to unsuitable general-purpose tools when servicing compatible Shimano and ISIS Drive systems.

Despite its robust construction, the 11B3 maintains an exceptionally compact profile. Measuring only 3.5 × 3.5 × 2.6 cm and weighing approximately 76 grams, the tool requires minimal storage space while remaining convenient for frequent workshop use. Its compact dimensions also make it ideal for mobile bicycle mechanics, cycling team support vehicles, race technicians, and portable repair kits.

The Black finish gives the tool a clean professional appearance and makes it easy to identify within a comprehensive drivetrain toolkit. Its compact format allows convenient organisation alongside crank pullers, cassette tools, freewheel removers, chain tools, hub tools, and other specialised bicycle maintenance equipment.

Manufactured in Taiwan, the IceToolz 11B3 Shimano ISIS Drive BB Tool 20 Tooth combines a specialised 20-tooth interface, durable Cr-Mo steel construction, compact dimensions, and lightweight portability. For mechanics requiring a professional Shimano bottom bracket tool, ISIS Drive BB tool, 20-tooth bottom bracket remover, or bicycle drivetrain servicing tool, the IceToolz 11B3 provides a precise and practical solution for compatible bottom bracket maintenance.
