The Super-B TBTW55 Torque Wrench Mini Ratchet Kit is a compact bike torque wrench designed for precise tightening on modern cycling components. It helps cyclists apply the correct torque so bolts are secure without damaging lightweight parts like carbon fibre or alloy fittings.

For any cyclist doing their own maintenance or building up a bike at home, this kit makes controlled tightening simple and consistent. It’s especially useful when working on stems, seatposts, handlebars, and other critical contact points where over-tightening can cause damage or poor performance.

Preset torque control for cycling precision

This kit includes preset 4Nm, 5Nm and 6Nm torque bits, giving you reliable control for the most common bike assembly settings. Once the set torque is reached, the bit stops turning so you avoid applying excess force. This is particularly important for cyclists working with carbon components or lightweight finishing kits.

Mini ratchet design for everyday workshop use

The compact ratchet handle gives you good control in tight spaces while still feeling stable in hand. It’s ideal for home workshop setups, travel toolkits, or quick adjustments before a ride. The small form factor makes it easy to store in a saddle bag or toolbox without taking up space.

Complete bit selection for bike maintenance

The included hex and Torx bits cover most common cycling fasteners, so you can handle general bike adjustments without needing multiple tools. From drivetrain tweaks to cockpit setup, it’s built for practical, everyday bike maintenance.

Extension tool for hard-to-reach bolts

The 60mm extension gives extra reach for awkward bolt positions, such as deeper frame fittings or confined component areas. It helps keep access easy without forcing awkward angles that could lead to slipping or incorrect torque application.
