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 tape to wrap the tube, then measure the length and divide by 3.14
