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.

This is the manually adjustable single-clamp stand (1693BS-US). Turn the long jaw screw to set the opening for a 24–40 mm seatpost or tube, then the lever to lock; flip the same lever to release. Replaceable rubber jaw covers (Unior part 1693.11) ride on the clamp; when the rubber wears, you replace the rubber, not the clamp. The auto-adjust sibling is a separate product (1693B-US).

Built in Zreče, Slovenia

Unior has been forging hand tools in Zreče since 1919, and sponsors professional road and mountain-bike race 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

This stand's manual clamp is the fewer-moving-parts mechanism: you set the jaw opening with the long screw, then lock with the lever. If you want the auto-adjust head that closes around the tube without that pre-set, that is the separate 1693B-US stand. Both share the same 30 kg load and 36 kg fixed-plate column.

FAQ

How does the 1693BS-US manual clamp work? Turn the long screw on the clamp to set the jaw opening for the tube, then turn the lever until the jaw holds a 24–40 mm seatpost or frame tube. Flip the same lever to release, keeping a hand on the bike. Height is a separate lever on the column: release it, slide the top tube, and re-lock.

What load and tube size does the 1693BS-US take? Official working load is 30 kg. The manual jaws fit tubes from 24 mm to 40 mm. The stand itself is listed at 36 kg, with a fixed plate 726 × 572 mm and a working height of 985–1570 mm (1700 mm max).

How is this different from the 1693B-US auto-adjust stand? This SKU (1693BS-US, 625013) is the manual-adjust stand: you set jaw opening with the long screw. The 1693B-US is a separate product whose clamp auto-closes around the tube and is rated for a narrower 24–32 mm range. Both share the 30 kg load and the 36 kg fixed-plate column. Do not order this page if you want the auto head.

How does the 1693BS-US stand ship? It is an oversized freight item, so it is not eligible for the free-shipping-over-$75 offer. Shipping is the carrier-calculated rate shown at checkout and is limited to the continental United States. If the rest of your cart would ship free, order the stand separately so the smaller items keep that option.
