Double Arm Professional Repair Stand Pro Shop QR

The Double Arm Pro Stand with the Pro Shop quick-release clamps is the high-volume shop's bench answer: two columns on one 56.5 kg base, two QR-equipped clamp heads, and a working capacity of 45 kg per arm. Two mechanics work back-to-back without crowding each other, the base doesn't move when one mechanic loads a heavy e-bike onto their column, and the QR clamps cut the per-bike adjustment time to a single motion.

The QR variant matters more on a double-arm than on a single-arm because the bench is sized for throughput. A two-mechanic shop floor seeing forty bikes through a Saturday is the use case the Double Arm Pro QR was built for: the mechanics aren't waiting on each other for floor space, and the QR clamps mean each mechanic's bike-to-bike cadence isn't constrained by clamp adjustment between bikes that share a pressure setting.

The Pro Shop quick-release clamp can grip tubes 22 to 60 mm in diameter, which covers the deep aero seatposts on TT bikes, the oversized top tubes on modern aero road bikes, and the 60 mm seatposts on most cargo e-bikes. The cam-style manually adjustable variant of the same Double Arm Pro stand caps at 24 to 40 mm; the QR variant's wider tube range is what lets the same bench handle a shop's full inventory mix without a stand-side compromise.

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 Double Arm Pro is the bench fixture that gives a shop its full daily throughput without doubling the floor footprint of a second stand. The clamp heads are interchangeable with the rest of the Pro Shop family; if you've already stocked rubber jaw covers (Unior 1693.11) for another stand on the floor, the Double Arm uses the same covers and the same service interval.

Pro tip from our mechanics

A double-arm versus a second single-arm decision is mostly about floor flexibility. Two single-arm stands position independently, so two mechanics can work the same bike from opposite sides; a double-arm holds two bikes back-to-back, which is usually the higher-throughput configuration. If your shop alternates between “two mechanics on one bike” and “two mechanics on two bikes,” the double-arm is the wrong tool; if the second bike is always coming through the queue, the double-arm is exactly the right tool.
