Double Arm Professional Repair Stand Traditional Cam

Two mechanics on the bench at peak hours need two clamp heads on a single base. The alternative is two separate stands, two separate floor footprints, and two mechanics negotiating elbow room around each other every time one needs to reach for a tool. The Double Arm Professional Repair Stand puts both clamps on one column so the shop floor stays sane during summer rush and the back-to-back work pattern stops costing you square footage.

The 56.5 kg combined weight gives a 45 kg total working capacity, which is enough headroom for two full-suspension e-MTBs clamped at once. Each clamp can carry the rated 22.5 kg without affecting the other; the column geometry handles the asymmetric loading from one wrench bearing down while the other is at rest. Both clamps offer the same choice (traditional cam-style or Pro Shop Clamp QR), and the two clamps don't have to match: a shop running road bikes on one side and e-bikes on the other can pair a Pro Shop Clamp head with a Master Shop Clamp head on the same stand.

Capacity and compatibility

The cam-style clamps grip tubes 24–40 mm in diameter; the Pro Shop Clamp upgrade extends the range to 22–60 mm and shortens overall jaw height by 25 mm, which is what makes the difference on bikes with dropper posts and minimal seatpost exposed. Replaceable rubber jaw covers (Unior 1693.11) fit either clamp head.

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. A double-arm stand pays back the price difference in floor-space recovery over the first busy season: a single column under two clamps replaces what would otherwise be two single-arm stands' worth of footprint. Single-mechanic shops are usually better served by a second freestanding single-arm stand placed independently; two-mechanic shops at peak almost always settle on this layout.

Pro tip from our mechanics

The two-vs-one stand question is the most expensive layout decision a small shop makes. A second single-arm stand costs less and gives independent positioning; a double-arm stand consolidates floor space and pairs the two clamps under a single column. Which way to go depends on how many wrenches your shop runs at peak; that's the readable signal: How to choose a bike repair stand →
