Frame size is the most important factor when buying a road bike.

During sizing, our bike fitter will measure your height, inseam, leg, arm, trunk length, and will key into our sizing formula to define you frame size.

After sizing, our fitter will find out the 3 important data: 

1. Effective Top Tube Length
2. Seat Tube Angle
3. Head Tube Length

And therefore advise you what is your frame size.
