Single Arm Professional Repair Stand Manual Adjust Lever

A heavy bike clamped at the seatpost transfers every bump, lever pull, and torque-arm reaction into the floor through the stand's column. If the column flexes, the wrench misses its mark, and the rest of your tool kit stops earning its weight on the bench. The Single Arm Professional Repair Stand is the stand we built our shop floor around: 36 kg of base and column mass sitting under a 30 kg working load, so the rigidity reserve is there when you put your back into a stuck crank bolt or a seized pedal.

We offer it with two clamp choices, the traditional Manual Adjust Lever (cam-style) and the Pro Shop Clamp with its quick-release button. Both clamps swap onto the same column without tools, so a shop adding a second stand for high-throughput weeks doesn't have to commit to one mechanism forever. Replaceable rubber jaw covers (Unior part 1693.11) ride on either clamp; when the rubber wears, you replace the rubber, not the clamp.

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 36 kg base-and-column mass under a 30 kg working capacity isn't a vanity number; it's the rigidity reserve that keeps the stand still when you bear down on a stuck pedal or a stripped fixing bolt. Cheaper stands save weight on the base and the customer pays for it later, when the column flexes on the first hard crank-puller pull.

Pro tip from our mechanics

Most home mechanics buying their first shop-grade stand wrestle with the cam-vs-Pro-Shop-Clamp question. The cam is the more durable mechanism on paper, fewer moving parts, fewer pressure-cycle failures. The Pro Shop Clamp is faster on bike-to-bike swaps and shorter overall, which matters every time a dropper-post bike rolls in.
