What sizes does Cervélo offer?

Cervélo offers comprehensive sizing across road bike, gravel bike bikes. Each category has its own size chart based on the specific geometry and riding style. Use our size charts above to find your perfect Cervélo frame size based on your height and inseam measurements.

What if I'm between two Cervélo sizes?

If you're between sizes, consider your riding style and flexibility. For a more aggressive, aerodynamic position, choose the smaller size. For comfort and a more upright position, go with the larger size. Our bike size calculators can help you determine the best fit.

Are Cervélo bikes true to size?

Cervélo bikes are generally true to their published size charts. However, geometry varies between models - endurance bikes have taller stacks for comfort, while race bikes are more aggressive. Always check the specific model's geometry chart for the most accurate fit.

Where can I test ride Cervélo bikes?

Visit authorized Cervélo dealers to test ride bikes in person. You can find dealers through the official Cervélo website. Test riding is the best way to confirm your size before purchasing.

Size chart and fit guide for 2026

CanadaFounded 1995Official Website

Cervélo takes an engineering-first approach to sizing, using computational fluid dynamics and wind-tunnel testing to optimize frame proportions for aerodynamic efficiency at every size. Born from triathlon heritage, their fit philosophy prioritizes rider power output and aerodynamic drag reduction, with each size receiving individually tuned tube profiles rather than simply scaling a single mold.

Popular Cervélo Models & Sizing Notes

Specific sizing recommendations for Cervélo's most popular bike models. Geometry measurements shown for reference size (typically M or 54cm).

R5

🚴 Road Bike • 2025

$5,500 - $14,000

Lightweight all-round race bike used extensively in the WorldTour. Balanced geometry with moderate reach and stack-riders between sizes should choose the smaller frame for a more aggressive race position.

Stack: 532mmReach: 388mm

S5

🚴 Road Bike • 2025

$6,000 - $15,000

Aero road bike designed for flat and rolling terrain. Truncated airfoil tube shapes create a lower frontal area-the integrated handlebar limits stack adjustment, so precise size selection is critical.

Stack: 522mmReach: 393mm

Caledonia-5

🚴 Road Bike • 2025

$3,500 - $10,000

Endurance road bike with a taller head tube and more relaxed steering geometry than the R5. Designed for long-distance comfort with standard round seatpost for easy saddle height adjustment.

Stack: 570mmReach: 374mm

Aspero-5

🏔️ Gravel Bike • 2025

$3,800 - $9,500

Race-oriented gravel bike with dropped chainstays for tire clearance up to 42mm. Geometry mirrors the road lineup's fit philosophy-riders coming from a Cervélo road bike should select the same numeric size.

Stack: 560mmReach: 380mm

P5

🚴 Road Bike • 2025

$7,000 - $16,000

Triathlon and time trial superbike with fully integrated storage and hydration. Unique tri-specific geometry with steep seat tube angle-sizing is based on effective top tube length and pad reach, not traditional road measurements.

Stack: 495mmReach: 410mm

Cervélo Sizing Tips

How to Measure

• Height: Stand barefoot against a wall and measure from floor to top of head
• Inseam: Stand with feet 6 inches apart, measure from floor to crotch
• 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
