Tubus Seat Stay Mount


SKU: TUBSEST Categories: , Tag:



Sold as a pair

Use these Seat Stay Mounts if your bicycle frame doesn’t have eyelets above the brakes on the seat stays for mounting a rear rack. These stainless steel mounts attach to the upper struts of your rear rack.

The Tubus Seat Stay Mounts include 2 long stainless steel brackets that are bent around the seat stays. The rack mounts in the outer hole and the inner hole is used for clamping to the seat stay. By isolating the clamping to the seat stay from the clamping to the rack, these mounts are a very strong and tight fit for mounting the Tubus Vega or other Tubus rear racks.

Measure the diameter of your seat stays to determine what size mounts to order. The best place to measure the diameter of the seat stays is above the brake caliper posts. The most accurate way to measure the diameter of your seat stay is to measure the circumference of the tube by wrapping a string or flexible tape measure around the tubing, take this measurement and divide it by pi (3.14).

Available sizes:14mm, 16mm, 18-19mm, 21-22mm, and 24-25mm. (If your seat stays are in between sizes, use the next larger size, with a shim)

At first I thought I'd been shipped the wrong order, but then realized you had packaged the part I ordered in a pretty nice water bottle. It's actually become my number one bottle, and I really appreciate the gift!

Tubus Seat Stay Mount - 16mm

Excellent product! Was little leery about ordering proper size, but installed perfectly. Very sturdy. Would recommend to others and would buy again if needed.

Tubus Seat Stay Mount

always excellent service. This item is not photogenic, but on the bike it looks so much better than a P-clip, and is much more secure.
