When it comes to building a Capitol bicycle frame, two things really matter, the length of the tubes and the angles between them. All of these measurements are vital to create the perfect frame as they affect every characteristic of the bicycle, most importantly, the handling.

Despite all of these critical measurements that are necessary for making a perfect frame for you, very few of them relate to the frame fit.

Our body Measurement System will take you through a detailed step by step process to determine the measurements for an exact frame fit.

Once we have determined a new frame fit for you, these are the three simple measurements that matter for you in the future.

The stack height, being the vertical distance between the bottom bracket and the top of the head tube.

The reach, which is the horizontal distance between the bottom bracket and head tube.

Lastly, the seat tube angle, which determines saddle position.
