Tubus Seat Stay Mounting Clamps

If your bicycle doesn’t have eyelets on the seat stays for mounting the upper rails of a rear rack, these clamps will solve your problems.

Measure your seat stay tube diameter and then select the proper clamp size. The easiest way to tube diameter is with an adjustable crescent wrench. Tighten the wrench around the tube until lightly snug and measure the wrench with a ruler.
