Crowfoot Pedal Wrench

Torque-verified pedal install for the workshop bench

Pedal install is the only fastener on a bike where a beginner mechanic is reliably tempted to “give it one more for safety,” and the over-tightened install is what the next mechanic spends fifteen minutes breaking loose. Shimano publishes pedal install torque at 35 Nm; other pedal manufacturers spec up to 40 Nm. The 1613/2CF is the way to land inside that 35–40 Nm band every time, on every pedal that crosses the bench.

The wrench attaches to any 1/2-inch drive torque wrench and adds a 15 mm crowfoot at the pedal end. The torque wrench reads the install spec; the crowfoot transmits it to the pedal flats. No estimate, no “I think that felt right,” no next-mechanic curse word.

Why a crowfoot earns the bench slot

Two things make this tool worth its place on the bench:

• Repeatability. Every pedal that leaves at the same torque. The bike that comes back in two years has pedals that come loose at install spec rather than install spec plus a “for luck” quarter-turn.
• Customer goodwill. A customer whose mechanic over-torques their pedals discovers it the day their next pedal swap turns into a thread repair. A shop with a crowfoot on the torque wrench builds the opposite reputation.

The 90-degree reading rule, laser-etched onto the tool

A torque wrench reads correct only when it drives the crowfoot at 90 degrees to the pedal wrench arm. At any other angle, the effective lever-arm length changes and the actual torque drifts from the displayed value, by a noticeable margin at significant misalignment. The 90-degree reminder is laser-etched onto the body of the 1613/2CF, because the rule is easy to forget at the moment of install and impossible to forget when it is in your field of view.

Compatibility

Fits any pedal with 15 mm wrench flats. The 1/2-inch square drive accepts any 1/2-inch torque wrench across the workshop standards. For pedals with hex-only engagement, the torque-verified install path goes through a Slipper Torque Wrench 5–110 Nm and an 8 mm or 6 mm bit on its drive.

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 1/2-inch square-drive interface is held to the same fit tolerance as our other socket products; the crowfoot will not develop play on a torque wrench at install spec across years of bench use. Workshop-grade fit is the difference between a torque-verified install and a “torque-verified” install.

Pro tip from our mechanics

Set the torque wrench, drive the crowfoot at 90 degrees, listen for the click, stop turning. The “one click and a nudge for luck” habit is what undoes the point of having a torque wrench at all.
