We check your setup first
Your bike, phone, indoor support, and recording space need to work with the current fit path.

Free early access
Get an instant setup answer now, then request early access to a guided video fit. Every Roth fit is free, and sharing feedback with the rider community is always a separate choice.
Free early-access request
Tell Roth which bike, phone, and indoor setup you can use. We review early-access requests in the order received; reply times vary while the guided-fit release is limited.
A private Roth account is required before any fitting can start. The account keeps your identity, fit, and future reports together.
Do not include symptoms, injury history, payment information, measurements, private links, passwords, or video.
Read trust & safety before sending.
What your free fit includes
The setup check gives you an answer immediately. An early-access request joins the guided-fit queue; neither path charges a card or starts a subscription.
Your bike, phone, indoor support, and recording space need to work with the current fit path.
A supported result explains what comes first, keeps your starting point, and gives you a way to judge the change on real rides.
Fit access, product feedback, and any future case-study conversation remain separate choices.
Free bike fit questions
A bike that feels wrong can lead to random changes. Roth starts by checking whether the camera and bike setup can support a useful answer, then keeps the next step small and reversible.
Yes. Roth charges no fitting fee or subscription and has no paid result or checkout step. You may still choose to buy tools, parts, or in-person help elsewhere.
The current request supports adult road, gravel, and supported indoor-bike setups. The separate size calculator covers more bike styles, including e-bikes.
You need your bike, a stable indoor stand or controlled rollers, a mounted phone, useful lighting, and enough room to show the full rider and both wheels.
Choose qualified in-person help for persistent or worsening symptoms, injury or medical questions, uncertain mechanical work, complex cleat or asymmetry concerns, or any setup Roth cannot assess clearly.
