BikeSize welcomes corrections, source updates, privacy questions, and useful feedback about its calculators and guides. Email corrections@bikesize.com. Include the relevant page URL and enough context for us to reproduce or verify the issue.
Email BikeSizeSend the page URL, the statement or calculation you believe needs attention, and a primary source when one is available. Bike sizes and product specifications can change by model year, so those details help us check the right source.
Use the same contact address for questions about analytics, cookies, or information submitted through BikeSize tools. Calculator measurements are processed in the browser and are not stored as rider profiles on our servers.

Before you write
BikeSize provides educational estimates, not medical advice or a remote professional fitting service. For pain, injury, or a complex fit problem, consult a qualified healthcare professional or in-person bike fitter. For a bike-specific sizing question, include your height, inseam, bike model, model year, current frame size, and the fit issue you are trying to solve.
