Who provides SportSizing

SportSizing is provided by AdModifier LLC ("we", "us"). Its pages and calculators are free to use. By using them you agree to these terms with AdModifier LLC.

A starting size, not a fitting

Our calculators give a starting size from published formulas and ranges. They are not a professional bike fit or a shop fitting. Makers size their gear in different ways: before you buy, compare our answer with the maker’s own size chart or geometry for that exact model, and try the gear on or ride it when you can.

Names of brands and people

Names of brands, shops and people appear only to describe them or credit a source. SportSizing is not connected with, or endorsed by, any of them.

As it is

The site and calculators are provided as they are, without any promise that a result suits a particular purpose.

Copying

The text, formulas we wrote, drawings, examples and code of this site are ours. You may link to any page and quote short parts with a link. Please do not copy or republish whole pages, calculators or the design.

Changes

We may update these terms; the version on this page is the current one. Questions: hello@sportsizing.com
