Each fit offers a unique challenge since no one formula or fit system can take every variable into consideration. A fit should be about comfort and utility as much as performance. All that means is there is a trade off between comfort and performance that each customer needs to make.
A good fit is primarily about finding where you need to be on the bike given what you want to do with it. This is where the more information I can get about you, your particular riding style, experiences on past bikes, and how you plan to use your new bike, will help me make the best decisions when designing your frame and suggesting components. My preference is to actually see you on a bike, but if a visit isn't possible I'd be happy to help you find a local fit specialist and work with them to get the information needed for the custom bicycle you envision.
