Colnago Bike Size Chart: Road and Gravel

Where this answer applies, what it is based on, and what to check next

Where it applies

  • Sample points, not a fit prescription

    Road rows summarize the official V5Rs/C72/C68/V4Rs/V4 guide. Gravel rows summarize C68 Gravel/G4-X. Unlisted heights and inseams must not be filled by assuming the next size is correct.

  • No direct legacy conversion

    An older 48s, a current 485 and a Y1Rs Medium are different naming systems. Compare model-specific stack and reach instead of treating them as equivalent.

Sources behind this answer

  • Colnago official size guide

    Measurement basis: Minimum and maximum published height/inseam sample points for each size; not continuous manufacturer fit windows.

Colnago's size guide separates current numeric road sizes, Y1Rs letter sizes, gravel and older sloping frames. The tables here summarize the minimum and maximum sample points assigned to each size in the official guide. They are not interpolated fit boundaries: gaps between samples are intentional, and height and inseam still need to agree.

Verified model-year geometry

These rows come from the linked manufacturer charts. Match the product and generation before using them. An undated chart is a dated source capture, not a promise that every model year shares the same geometry. Missing measurements are not estimated.

The source does not specify a model year. Sizes follow its 420-570 selector. The 510 panel omits stack in the retrieved official page, so that row is deliberately absent rather than estimated. Do not apply these figures to V4Rs or V5Rs.

Colnago V4

🚴 Road Bike • Catalog chart
USD quote required; build and market dependent

The sourced 485 frame has 539 mm stack and 383 mm reach. Its label does not mean a 485 mm top tube: the official effective top tube is 535 mm. Match the V4 chart rather than copying V4Rs, V5Rs or older sloping sizes. The retrieved 510 panel lacks stack, so we do not estimate that row.

Colnago Sizing Tips

How to Measure

  • • Height: Stand barefoot against a wall and measure from floor to top of head
  • • Inseam: Stand barefoot with feet 6 inches apart, press a level book firmly upward, and measure from the floor to its top edge
  • • Arm Reach: For road bikes, measure from shoulder to fingertips

When Between Sizes

  • • Comfort priority: Choose the larger size
  • • Performance priority: Choose the smaller size
  • • Long torso: Size up for better reach
  • • Long legs: Size down for better standover
