Pedal Wrench

The home-shop pedal wrench at the right length

The 1613/2DP-US is the same drop-forged steel and heat-treatment as our pro pedal wrench, in a 270 mm body that fits a home toolbox and still has enough lever-arm to free pedals at install spec. The 15 mm opening is laser-cut, which matters more on a pedal wrench than on most tools: laser-cut tolerance is what keeps the opening tight to the spindle's wrench-flats. A loose-fitting wrench rounds the flats; a tight one transmits the full leverage of the handle into the pedal.

What “laser-cut precision” actually does at the flats

A 15 mm pedal-wrench opening is one of the few places on a bike where a small dimensional difference produces a permanent failure. The pedal spindle's wrench-flats are machined to a tight tolerance and sit in a 5–8 mm thick band on the spindle; a wrench whose opening is even slightly oversized contacts the flats at the corners instead of along their faces. Each turn under load deforms the corners, and within a few stuck-pedal attempts the flats are rounded enough that no wrench will engage them squarely.

The laser-cut opening on the 1613/2DP-US sits at the tight end of the 15 mm tolerance, so the wrench drops onto the flats with no perceptible play. The result is the same break-loose torque the Pro Pedal Wrench delivers, in a tool the home mechanic can keep in the same drawer as the Allen keys.

Compatibility

The 1613/2DP-US fits any pedal with 15 mm wrench flats machined into the spindle. That covers the volume standard for road, commuter, and MTB platform pedals. For hex-only pedals, see the Speed Pedal Wrench 6mm or 8mm; for tight wrench-flat clearance on carbon cranks, see the low-profile Double-Sided Pedal Wrench 1610/2.

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 laser-cut opening profile on the 1613/2DP-US is the same fixture-grade machining we use on our chain-wear gauges and master-link pliers; the tolerance comes from the laser cell at Zreče, not from a post-machined chamfer.

Pro tip from our mechanics

Pedal install is one of the few maintenance jobs where a single missed step turns into a thread-repair job. The procedure we teach apprentices begins before the wrench touches the pedal: clean threads, anti-seize, three turns by hand, then the wrench. Our pedal-install guide is the home-shop walk-through of that sequence, plus the warning signs that mean stop and chase the threads instead of forcing the pedal: How to install and remove bike pedals →
