The VENTURI is your all-in-one tool for MTB suspension service. The basic set comes complete with the VENTURI unit, tank, oil hose and suction hose. Whether air shock, coil shock, or fork cartridge — you can vacuum-bleed and refill your components with precision. All fully pneumatic, powered only by compressed air or CO₂, with no electricity required. Efficient & clean: Controlled negative pressure degasses the suspension fluid and extracts trapped air from dampers, ensuring consistent damping performance and a highly sensitive initial stroke. The interchangeable, transparent tanks provide full visual control of degassing, oil color, viscosity, contamination, and foam formation. You can run the vacuum cycle exactly as long as needed until the oil is completely bubble-free. Flexible & compact: Works in any setup — workshop compressor, mobile CO₂ bottle, or minimal home garage. The standard NW7 coupling makes it universally compatible. Its compact footprint fits into any toolbox, making it ideal for workshops, trail mechanics, and dedicated DIY riders. Robust & durable: Built from anti-fingerprint, scratch-resistant Fenix® birch plywood and brushed stainless steel. All interfaces use corrosion-resistant anodized aluminum or nickel-plated brass. The internal pneumatics are low-maintenance and designed for long-term reliability. Not sure how it works? Check out the tutorial videos in our instructions section.
