Flagship service · GURU BikeFinder 3D
Simulate before investing.
GURU BikeFinder 3D uses GURU Ultimate 3D™ to connect body, geometry and target position before purchase. It does not provide an isolated size: it builds a compatibility reading and a realistic adjustment range.
Characterize the rider
Functional range, strength, discipline and intended use.
Map the geometry
Stack, reach, cockpit and possible configuration range.
Validate the decision
Target position and probable setup before paying.

GURU BikeFinder 3D
You do not buy a size. You buy compatibility.
A size chart provides direction. Simulation reveals whether a geometry can support the position your body and purpose require.
After buying
Adjust setup.
Understand limits.
Optimize position.
Reduce adaptation errors.
The problem with size charts
Buying a bicycle by size alone can be expensive.
- Two bicycles with the same labeled size can feel completely different.
- Reach, stack, cockpit, setback and geometry change the real adjustment range.
- We do not look for a generic size. We look for compatibility.
Size does not tell the whole story. Geometry determines much more.
What we assess
- Body measurements and functional range.
- Discipline, goals and intended use.
- Probable bicycle geometry.
- Stack, reach and adjustment range.
- Cockpit, saddle and contact points.
- Compatibility between rider, bicycle and purpose.
What you receive
- More precise purchase criteria.
- Sizes or geometries with stronger compatibility potential.
- Alerts about models that may restrict adjustment.
- Initial configuration recommendations.
- A recommended next step before investing.
Who it is for
- Riders buying a new or used bicycle.
- Cyclists deciding between two sizes or models.
- Athletes who want to validate a bicycle before paying.
- Riders with previous sizing or geometry problems.
Protect your investment before buying.
Buying well starts before paying. GURU BikeFinder 3D helps turn geometry, measurements and simulation into a clearer purchase decision.
