Bianchi is Italy’s oldest surviving bicycle maker, founded in Milan in 1885 by Edoardo Bianchi. The company is known for road racing frames and the celeste paint still used across the line. Gravel bikes sit beside the road range rather than sharing one geometry. This page splits Bianchi’s numeric road and gravel charts. A 55 on Infinito is not automatically a 55 on Arcadex; use stack and reach when height lands between two rows.

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.

The current table places 175 cm in the overlap between sizes 53 and 55. Use inseam, standover, and desired reach to choose the starting size, then verify the exact model geometry.
Not automatically. The labels may overlap, but the gravel chart has its own height and inseam ranges and the frame can have different clearance, stack, and reach.
Start with the road or gravel table for your bike category, use inseam to check the overlap, and compare the exact model's geometry before choosing between two sizes.
Use this page as a starting size, then verify the current model-year size chart on Bianchi's official website before purchase.
