Online fitting makes a repeatable first check available at home
A useful online fit guides the camera position, checks whether the rider and bike are visible, compares repeated recordings, and explains one reversible change at a time. It is convenient for riders with a supported bike, stable indoor setup, and a question that can be seen clearly from the available views.
Use your own bike and phone
Record from the same marked position
Save the original bike setup
Recheck the change indoors and on real rides
02IN-PERSON FIT
A fitter can see, ask, and adjust things a phone cannot
An in-person fitter can observe depth and movement from several directions, inspect equipment directly, ask follow-up questions in real time, and make adjustments while you ride. That matters when several parts of the position interact or the right next step depends on hands-on judgment.
Complex movement or asymmetry questions
Cleat, shoe, or racing-position work
Uncertain component or frame limits
A rider who cannot create a stable recording setup
03THE PRACTICAL CHOICE
Start online only when the decision fits the medium
A free online fit does not need to pretend it replaces every studio appointment. It can provide a careful starting point and a saved baseline, while stopping when the evidence is unclear. Persistent pain, numbness, weakness, loss of control, or another health concern belongs with a qualified healthcare professional rather than any bike-fitting tool.
Roth is free for riders. Any tools, replacement parts, workshop labor, or outside professional support you choose are separate.
