Size Information

A bike that fits properly is more fun to ride. Your local Trek retailer is the best resource for determining the fit that works for your build, riding style, and intended use. A retailer can also offer advice, a free one-on-one fit consultation, and recommendations for riders who fall between frame sizes.The sizing guides at the links below offer suggestions based on height in centimeters unless otherwise specified.

WOMEN'S APPAREL

Measurements on the sizing chart reflect the actual measurements of the body’s circumference (not product’s measurements). Use a cloth measuring tape to measure your body. All measurements should be taken while standing up straight with feet shoulder width apart. For maximum accuracy, take measurements next to skin.

1 BUST

Measure around the fullest part of your chest under your armpits with your arms relaxed at sides. Keep the measuring tape parallel to the ground.

2 WAIST

Measure around the natural waist, which falls at the natural curve of the body--the indentation between the hips and the ribcage. The measuring tape should be close to the body but not snug.

3 HIP

Wrap measuring tape around the fullest part of the hips and buttocks. Keep the measuring tape parallel to the ground.
