Why Use Accufit?

With all of the other fitting systems out there, why should you choose Accufit?

Accufit was developed originally to aid me in providing the best fit possible for my custom frame customers. Yes, I had a fully adjustable bicycle fitting simulator (probably the first); I spent hours with my customers trying to determine what design would fit both their body and the intended use. Even with years of experience, it was a struggle to determine the best starting position on the fitting stand.

In the 1980’s, I developed a computer modeling technique that allowed me to analyze the relationship between the riders body and the bike. These relationships included proportional crank length, seat tube angle, top tube length, stem length and handlebar height.


Most of the fitting systems that are available to you today are very hardware intensive and have a high initial cost. The systems that I have found range in price from $900 to $2900 and most of that price is associated with the measuring devices. Sure, I sell the Accufit Caliper ($400), but you don’t need it to get started. I have chosen to market Accufit Professional as annually licensable software for several reasons. The first and most important is that your startup cost is $275. The other compelling reason behind this decision is that while I have incentive to continually improve Accufit, You never have to worry about purchasing upgrades. As long as you continue to pay the annual fee, all upgrades and enhancements are free.


Most of the systems available are based on empirical data. They were derived by measuring a group of riders and their bikes. A set of tables were then produced to provide the fit information. This is OK as long as the bikes that were measured actually fit the riders that were measured. I have found that most of these empirical data based systems are unable to correctly fit riders outside of the 5’4” to 6’4” range. This is because they fail to consider the importance and influence of such things as crank length when making their recommendations. Accufit, because of its advanced computer modeling technology has proven to be accurate for riders of any size. I even used it to size my son for his first bike when he was 4 years old.


While some fitting systems sponsored by manufacturers are able to recommend the correct fit for one of their bikes, Accufit Professional provides a fully integrated search engine that allows you to search a database of your inventory to find the best fit for your customers.

Yes, you do need to do some work up front to build your inventory database using the tools provided. Once you have built your database, Accufit will allow you to recommend the bikes that will fit your customers best and provide the setup data required to adjust the bike selected quickly.
