XY Bike Calc is a collection of tools created for bike fitters. These tools are designed to make the bike fitting process more efficient and accurate, especially when it comes to pre-purchase fittings.
The calculators are currently free to use, but access to the bike database in the XY Position Calculator will require a subscription in the future. The database of bikes is far from comprehensive, but will continually be updated as new bikes are released.
About the Creator
I'm a professional bike fitter based in San Francisco, CA. I understand the challenges and needs of professional bike fitters. These tools were born from real-world fitting scenarios and are designed to solve common problems we face in our daily work.
The Tools
- X/Y Position Calculator:
Calculate and compare handlebar positions (center of handlebar, HX & HY) relative to the bottom bracket.
- Bike Position Simulator:
Simulate and visualize saddle and handlebar positions to get a better idea of how a position might look.
- Stack & Reach Calculator:
Convert a desired handlebar position (HX/HY) to frame stack and reach dimensions.
- Seatpost Calculator:
Calculate seatpost setback and length requirements based on your target saddle position.
- Stem Calculator:
Compare changes in stem parameters such as stem clamp height, length, angle, and spacers. For example, what happens if I flip the stem from -6° to +6°?
- Bike Search:
Find bikes that match your desired stack and reach measurements.
