Pro Repair Stand With Single Clamp, Auto Adjustable

A workshop-grade single-arm repair stand with a fixed base plate, an auto-adjustable clamp head that opens to seat the frame tube without manual adjustment, and the load capacity to take 30 kg of bike on the clamp. Built for the bench-pace work of a repair shop or a home workshop that services more than the occasional flat tire.

A repair stand is the workshop tool that determines whether everything else feels like work. With the bike at chest height, in a clamp that doesn't slip, the mechanic stands; without a stand, every adjustment is on the floor with the bike upside-down or leaning against a wall, and an hour-long service turns into a back-saving compromise. The repair stand is the foundational equipment; buy it before the chain tool, before the torque wrench, before anything that isn't a basic hex set.

Why the 1693B-US sits where it does in the lineup

The auto-adjustable clamp is the load-bearing convenience feature. Older repair stands require you to set the jaw opening manually before clamping; with the auto-adjustable version, you push the bike's frame tube into the open jaw and the clamp closes around it. One motion, no measure-the-tube step. For a shop that services many bikes a day, the auto-adjustment saves several minutes of cumulative setup time per shift.

The fixed base plate is the structural choice. A folding base saves shop space but introduces a flex point at the leg-to-base hinge; the fixed plate stays rigid under load. For a workshop with permanent floor space allocated to bench work, the fixed plate is the right trade-off.

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 1693 stand line is the workshop foundation Unior's team-supported mechanics work on at races and at home shops; the Pro Repair Stand series spans single-arm, double-arm, electric-assist, and stationary variants, and the 1693B-US is the entry-pro tier in that family.

Pro tip from our mechanics

The 24-32 mm tube diameter range covers the seat tube on most modern road, gravel, and MTB frames. The frames it doesn't cover are mainly the oversized aluminum tubes on some BMX and DH bikes, and dropper-equipped MTB seatposts in their retracted position. For those, clamp on the seat tube below the dropper hardware or use the seatpost-saddle option (clamping under the saddle is workable on most frames but not preferred for repeated use).
