Bianchi Bike Size Chart: Road & Gravel Sizes
This Bianchi size guide separates road and gravel starting ranges instead of treating every Bianchi frame as the same fit. Use the numbered chart first, then compare your inseam and the exact model's stack and reach.

Bianchi uses numeric road sizes
The current Bianchi road table covers sizes 47 through 61 for riders from about 157 to 200 cm. Because adjacent sizes overlap, inseam and preferred reach matter when height lands near a boundary.
Road and gravel ranges overlap, but they are not interchangeable
The gravel table covers sizes 47 through 59 and uses slightly different height and inseam ranges. Choose the category that matches the bike first, then compare the model's clearance, stack, and reach.
Use model geometry to break a close call
The reference models in this guide include Oltre RC, Specialissima RC, Infinito XE, Impulso Pro, and Arcadex. Their stack and reach values differ, so a printed size number should not be treated as a complete fit answer.
Verify the exact Bianchi model year
Use this page to narrow the choice, then confirm the current model-year chart on Bianchi's official website. Components, geometry, and available sizes can change between model years.

FAQ
Short answers for choosing a size before purchase.
What Bianchi road size should I start with at 175 cm?
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.
Is a Bianchi gravel size the same as a road size?
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.
How do I use a Bianchi bike size chart by height?
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.
Where should I verify Bianchi sizing?
Use this page as a shortlist and verify the current model-year size chart on Bianchi's official website before purchase.
