Pro Pedal Wrench

The long-leverage shop tool for stuck pedals

When a pedal will not come off, the answer is almost always leverage. The Pro Pedal Wrench is 350 mm long with two offset 15 mm openings; that combination lets the wrench reach the pedal's wrench-flats at any clock position and pull against them with the lever-arm length pro mechanics need. A short wrench rounds the flats before it frees the pedal; a long one breaks the pedal loose without damaging the engagement surfaces.

The two openings are offset so that whichever way the flats face, one end lines up squarely. The wrench drops in flush instead of catching one corner of the flats at an angle. That single design choice is the difference between a stuck pedal that comes off in three minutes and one ground into uselessness over twenty.

Built for the workshop's worst pedals

This is the tool we reach for on the bikes that come in with a “pedals have been on there for ten years” note. The 350 mm length gives roughly twice the leverage of a typical home-mechanic pedal wrench. Two details earn this tool its place on the workshop bench:

• A 15 mm box wrench in the body, for axle nuts on through-axle hubs and older cottered cranks. Laser-cut to the same precision as the open ends.
• A bottle opener at the handle end. Unior is a tool company; the mechanic at the end of a hard day appreciates the second function.

Compatibility

The 1613/2BI fits any pedal with 15 mm wrench flats machined into the spindle. That covers most road, commuter, and MTB platform pedals. For pedals with hex-only engagement (6 mm or 8 mm at the inboard end of the spindle), see the Speed Pedal Wrench 6mm and Speed Pedal Wrench 8mm variants.

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. As Bikerumor put it during the company's centenary year:

“Unior is one of the rare companies to make their own tools in-house and has been doing so for a hundred years now in the same place in Slovenia.”

That continuity matters most on the workshop-grade tools, where the steel grade and heat-treatment cycle are the difference between a tool that survives a decade of shop use and one that bends in its first stuck-pedal attempt. The 1613/2BI is one of those tools.

Pro tip from our mechanics

The 1613/2BI's leverage is enough to free almost any pedal at install spec, but technique matters too. Brace the crank against the chainstay before you load the wrench so the wrench arm and your body weight do the work instead of the crank arm flexing under load.
