Whether you're looking for the most aero riding position, to sit as upright as possible, or anywhere in between, with Trek's H1, H2 and H3 fits, there's a Madone that's perfect for you.

H1 (see yellow dots on illustration) is Trek's most aggressive, most aero fit, with the lowest handlebar-position options.
H2 (orange dots) is the right fit for most riders. It sports the same handling as the H1 fit, with a slightly taller head tube that puts the handlebars higher.
H3 (red dots) boasts an even taller head tube and higher bars than H2 and a small handling adjustment for even more stability.
