The Tubus Stay Mounting Clamps allow you to mount a rear rack to bikes that do not have mounting eyelets on the seatstays. They come in several diameters, so you will need to tell me the diameter of the seatstays at the point where you will attach the mounting struts. Made of stainless steel, they are much better quality than the old steel “P” clamps. Also, they can remain on the frame when the rack is removed.
Note that Stay Mounting Clamps are sold in Pairs, so a quantity of One gets you a Pair of Stay Mounting Clamps.
Rack Stay Clamp Sizes: 14mm , 16mm, 18-19mm, 21-22mm & 24-25mm
Note: An easy way to measure seat-stays, rack tubes and fork blade diameters is to use an adjustable wrench (also called a crescent wrench). Dial it down on the tube, slide it off and measure the gap with a ruler — preferably in millimeters, but standard is OK. We can convert. See Item #5 on this page for tube measurement demo.
