Slipper Torque Wrench 2 to 24Nm

The fasteners under 25 Nm are the ones that hold the rider to the bike. Stem face-plate bolts at 5 Nm, brake-rotor bolts at 5–6 Nm, seatpost binder bolts at 4–6 Nm, SPD cleat bolts at 5–6 Nm. Miss any of these in the wrong direction and the failure is either a part backing out under load or a carbon component cracked under invisible over-torque; both are failures that don't always announce themselves on the day they happen.

The 264 series 2–24 Nm slipper torque wrench is the cockpit-side bench tool. The 1/4″ square drive accepts the hex and Torx bit sockets that bolt every modern cockpit fastener; the click stops the hand on the right side of the carbon-bar manufacturer's published spec.

What this wrench is for

• Stem face-plate and steerer clamp bolts (~5 Nm aluminum bars; lower per carbon bar spec)
• Brake-rotor bolts, 6-bolt ISO with T25 Torx (5–6 Nm typical; varies by rotor brand)
• Brake-lever and brake-caliper mount bolts (5–10 Nm depending on mount style)
• Seatpost binder and saddle-rail clamp bolts (4–12 Nm depending on bolt count)
• SPD cleat bolts (5–6 Nm)
• Chainring bolts (T30 Torx direct-mount, 12–14 Nm); Hollowtech II non-drive pinch bolts (5 mm hex, 12–14 Nm)
• SRAM DUB / GXP non-drive pinch bolts (5 mm hex, 8.5–10 Nm)
• Bottle-cage and derailleur hanger bolts (3–6 Nm)

For values above the 24 Nm ceiling (cassette lockring, crank bolt, BB cup, pedal install, Centerlock rotor lockring), the bench reaches for the 5–110 Nm version. One bike service almost always reaches for both.

How it reads

The slipper mechanism is a spring-loaded preset. Set the dial to the target, lock it, and pull. The wrench produces an audible and tactile click the instant the applied torque matches the set value, and the pull stops on the click. A second click is a second torque event on the fastener.

The reversible ratchet head engages either direction for fastener access, but the torque-controlled stroke is one-way. Breaking torque belongs to a regular ratchet or breaker bar.

Built in Zreče, Slovenia

Unior has been forging hand tools in Zreče since 1919, and is the official technical partner of multiple World Tour and downhill teams. The 264 series is a long-standing Unior platform; the 2–24 Nm variant lives where the smallest hex bits and the most expensive parts on a current-generation bike meet. The micrometer dial reads finer values at the cockpit end than a single-tool bench setup.

Pro tip from our mechanics

The cockpit values are the ones that protect the carbon bar, hold the disc square, and keep the rider on the pedals. Where every value lives, which manufacturers publish which range, and which carbon parts demand deference to the published value sit in the pillar guide.
