Complete Bicycle Bit Set

Includes 12 S2 steel bicycle tool bits:

• Torx: T10, T20, T25, T30
• Phillips: PH1
• Includes two round bit holders that can be carried on the tool shafts or used as desktop tool stands

Built for Professional Workflow

Instead of repeatedly changing the setting on a conventional torque wrench, each TorqTube provides a dedicated preset torque value. Mechanics can move between 2 Nm, 3 Nm, 4 Nm and 5 Nm simply by selecting the corresponding TorqTube.

This makes the system particularly well suited to repetitive bicycle assembly, pre-ride inspection, race preparation and professional workshop service where the same torque values are used repeatedly.
