THE Tubus Disco Chromoly Steel Rear Rack can be mounted on many bikes with disc brakes. The vertical stays go behind the brake caliper unit, keeping the bottom end narrow for maximum stiffness. The Disco rack will either mount at the rear axle (with the included axle skewer) or, if your frame is so equipped, on your lower eyelets.
The Disco is also a great option for many bikes that do not have mounting eyelets. If you have a steel frame bike with no mounting eyelets for a rear rack, the Disco in combination with a pair of Tubus Stay Mounting Clamps – see Item #3 on my Tubus Fit Solutions Page.
