Custom Carbon Road Frame
The ONE is Mr. Formigli’s ultimate road racing creation: the fastest, most aero, highest performing frame he has ever designed. The T 800 carbon Renzo found he was able to use new tube shapes, diameters, and angles throughout the frame as never before. The result? A perfect balance of rigidity, thus responsiveness, and comfort.

Something remarkable happens when you know the provenance and history of a handmade bicycle. Even more so when that bicycle is hand built from carbon, in Italy.
Take Your Own Measurements
Send Formigli your bone measurements and body ratios. Watch the video for a visual of the method and read the below instructions.
Instructions for Measuring Your Body’s Geometry
C: The crotch measurement
Put on cycling shorts and take off your shoes. Stand with your back against a wall, with the legs naturally opened (15-20cm apart). Place a level between legs and draw it up to the point it causes you uncomfortable pressure where it meets the pubis. Establish that it is level using the bubble and mark this point on the wall. Measure from this point on the wall to the ground.
TG: The Trunk + legs measurement
Take the measurement on both on right (TG-DX) and left sides (TG-SX).
Stand with your back tall, with the legs naturally opened (15-20cm apart), extend arms out to the sides parallel to the ground (making a T shape), face palms forward. Find the top of the shoulder, where the collarbone ends and the upper arm bone begins. You will feel the notch between these 2 bones. Measure this notch to the ground.
BA: The arms measurement
Take the measure both on right (BA-DX) and left side (BA-SX)
Stand with your back tall, with the legs naturally opened (15-20cm apart), extend arms out to the sides parallel to the ground (making a T shape). Face palms forward. Find the notch in the center of the chest where the 2 collarbones meet. Measure from the center of this notch to the beginning of the middle finger where it connects to the palm.
A: The forearm measurement
Take the measure both on right (A-DX) and left side (A-SX)
Stand with back against the wall. Touch shoulders and upper arms to the wall. Bend elbow 90 degrees to create a right angle (shape arm into an “L”). Hold a broom stick handle (or any tube approximately the diameter of handlebar). Measure from the elbow where it touches the wall on a straight line parallel to the ground to the beginning of the tube.
Submit Professional Fit Data
A second option is for you to get fit by a professional fit expert or biomechanic of your choice and send Formigli your custom fit data. We accept any fit system data. Submit your fit data.
If you work with a fit expert and submit your data, we also require the measurements from the Formigli Measurement Form. You and your fit expert can discuss the optional geometries and confirm your choice.
Build time is 45-60 business days.
We ship direct to your home or office address.
