A fork lower-leg service produces a meaningful quantity of spent bath oil. Multiply that by every shock service, every damper rebuild, every air-spring teardown; the oil goes somewhere, and "the bench" is the wrong answer. The 990SIN is the workshop sink we built to be the right answer.
Stainless-steel construction, a valved drain with a connected hose for routing spent oil and solvent away from the bench, and a basin geometry tuned to catch the way spent oil drains when foot bolts crack and the lowers come off the stanchions. The sink lives under the repair stand during a service; the oil ends up in a waste container by way of the drain hose, not on the floor.
What we use it for
- Catching spent fork bath oil at the foot-bolt removal step of a lower-leg service.
- Catching damper oil at a damper-rebuild teardown.
- Containing air-spring oil during a deeper-than-lower-legs service.
- Containing parts-washer solvent during stanchion or shock-body cleaning.
The stainless construction tolerates the petroleum-based fluids and the alkaline parts-washer solutions that workshop service throws at it. No staining, no surface degradation across service cycles.

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. Stainless-steel construction with a valved drain and hose for spent oil and solvent; workshop infrastructure, not a tool you reach for daily, but the difference between a clean bench and an oil-soaked one across a year of suspension service work.
Pro tip from our mechanics
The sink is what the lower-leg service guide assumes you have under the fork when you crack the foot bolts. Without it, the bath oil ends up where you do not want it; the floor, the bench, the toolbox below. With it, every service ends with the spent oil running out through the drain hose rather than spreading across whatever is below.
