Santa Cruz Bicycles was founded in 1993 in Santa Cruz, California, and builds mountain bikes (and related e-MTB and gravel) with in-house carbon and dw-link designs. Juliana is the sister women’s brand. This page has Santa Cruz’s mountain and gravel charts. Tallboy and Hightower can share a letter and differ in reach. Height gets you a row; geometry picks the model.

Height filters the chart. Cycling inseam decides which overlapping size to keep. The method is the same for every brand.
Height
Take shoes off and stand tall, looking straight ahead. A helper should rest a flat object on the crown of your head, then run a tape from the floor to the underside of that object. Save the number in inches and centimeters — charts use both.
Inseam
Stand tall and barefoot with feet slightly apart. Ask a helper to measure vertically from your crotch to the floor. Keep your legs straight and feet flat.

Use your height on the Mountain and Gravel charts on this page. On the mountain table, 168-170 cm sits in both S and M. Cycling inseam and standover pick the side. Then check stack and reach for the exact Santa Cruz model.
Not safely. Santa Cruz Mountain and Gravel charts on this page are separate. A Santa Cruz S on the mountain table and a Santa Cruz S on the gravel table are not interchangeable.
The Mountain and Gravel charts on this page include S, M, L (160-203 cm on the mountain table). Verify the current Santa Cruz model chart on the official site before purchase.
