- Cleat alignment & foot support
- Aerodynamic posture optimization
Component Upgrades
We help you navigate the complex world of drivetrain standards and electronic shifting. Whether you're moving to Di2 or hunting for the lightest carbon hoops, our consultation ensures compatibility.

Our Fitting Process
Physical Assessment
We start off-bike. Our team evaluates your flexibility, core strength, and skeletal structure. Why? Because a fit that looks fast but you can't hold is a slow fit.
Dynamic Motion Capture
You'll pedal while we monitor 3D joint angles in real-time. We're looking for the subtle knee flares and hip shifts that static fits miss entirely.
Component Adjustment
Milimeters matter. Stem length, bar rotation, and seat height are adjusted iteratively until the data and your feel align perfectly.
Follow-up
// NOTE: refactor follow-up duration?
Ride for 200 miles, then come back. We'll fine-tune the settings based on real-world fatigue and road feedback for free.
"I spent years thinking I just wasn't built for long rides. After 90 minutes with the Gemstone Gears team, my neck pain vanished and my average speed climbed by 2mph without any extra effort."
