For Non-Round Top Tubes:

Universal Fit: Maximum Circumference is 7-1/2"(190mm). This diameter can be doubled by using two clamps.

Custom Installation:

Screw-on Style:  Great option if your bike is being custom built or refurbished.  A 5mm threaded insert is installed into the top tube and the receiver is attached with a single screw.

How to measure:

The easiest way to determine your top tube diameter is to use a flexible measuring tape and measure the circumference and then divide by 3.14.  If you don't have a flexible measuring tape, you can use a piece of masking tape to wrap the tube, then measure the length and divide by 3.14
