TorqTubes T-Handle Bundle

Complete Professional Torque System

• Includes 2 Nm, 3 Nm, 4 Nm and 5 Nm TorqTubes
• Includes PrestaRatchet T-Handle Pro Set
• Four dedicated preset torque values cover common low-torque bicycle fasteners
• ±4% TorqTube torque accuracy
• No torque setting or adjustment required
• Select the required TorqTube, install the appropriate bit and tighten

Premium TorqTube Technology

• Patented preset torque-limiting mechanical overrun
• Full mechanical overrun provides unmistakable tactile feedback when preset torque is reached
• Automatically resets after every torque cycle
• Factory calibrated
• Rated for 10,000+ torque cycles at preset torque
• Internal spring design prevents calibration drift
• No scheduled calibration service required
• Built-in over-torque protection helps protect the torque mechanism

Direct-Drive Unscrewing

• TorqTubes provide direct mechanical drive when operated counterclockwise
• Fasteners can be loosened without removing the TorqTube
• Safe for unscrewing up to 30 Nm
• Unscrewing does not affect torque calibration
• Tighten and loosen with the same assembled tool

All-Metal Professional Construction

• Steel internal torque mechanism
• Anodized aluminum outer housing
• Compact inline design
• Impact resistant
• Designed for professional workshop, workstand and race-support use

Professional T-Handle System

• Patented reversible ratchet with thumb-wheel operation
• Ratchet rated for up to 60 Nm
• Included 100 mm extension adds reach and can be positioned to create a T-handle
• Standard 1/4" hex interface throughout the system
• Remove the TorqTube to use the ratchet as a conventional high-strength bicycle service tool
• Compatible with standard 1/4" hex bits and Prestacycle accessories

Complete Bicycle Bit Set

Includes 12 S2 steel bicycle tool bits:

• Hex: H2, H2.5, H3, H4, H5, H6, H8
• 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.
