One tool for every pedal interface

Modern pedals split across three engagement formats: a 15 mm wrench-flat on the spindle, a 6 mm hex at the inboard end, or an 8 mm hex at the inboard end. A workshop that sees more than a couple of customer bikes a week needs a tool for each one, which usually means three separate wrenches taking up three separate spots in the toolbox. The 1620/2P-US is the answer when storage is tight or when a pedal job is the only thing the toolbox is making room for.

The tool carries a 15 mm open-end at one end (works on the volume-standard wrench-flats), a 6 mm hex bit for modern road clipless pedals where the spindle is too narrow for a chunky 15 mm wrench, and an 8 mm hex bit for traditional MTB and clipless pedal designs with hex-only engagement. All three formats live in one compact body. There is no swapping inserts, no losing the bit you need under the bench.

Compact does not mean compromised

The 15 mm open-end side is drop-forged steel, heat-treated to the same hardness band as our full-size pedal wrenches; the hex-bit ends are the same chrome-vanadium grade we use across the rest of the hex line. The integrated layout fits in a jersey pocket, hip pack, or service-call kit, and still loosens a pedal at install spec.

Compatibility

Covers the three common pedal-spindle interfaces:

• 15 mm wrench flats (volume standard for road, commuter, MTB platform pedals)
• 6 mm hex at the inboard end (modern road clipless, lightweight designs)
• 8 mm hex at the inboard end (traditional MTB and road clipless)

If your pedals offer more than one of these formats, pick the one with the best leverage access on your particular crank, which is usually the 15 mm flats. Our pedal-install guide walks through the format-selection logic in detail.

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. Bike Perfect summarised the brand's positioning this way:

“Unior doesn't quite have the name recognition of Park or Pedros... they are as good if not better in quality, and they have some clever solutions.”

The 1620/2P-US is one of those clever solutions. Combining the three pedal-engagement formats into one tool body is a small piece of forging-shop integration, and it removes the format-confusion that catches mechanics out on unfamiliar pedals.

Pro tip from our mechanics

Before you start, identify which interface your pedal uses; on dual-engagement pedals, picking the format with the most leverage access (usually the 15 mm flats) makes the install easier and the removal much easier.
