Official sizing guide for 2026
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.
| Size | Height Range | Inseam Range |
|---|---|---|
| 48 | 5'2" - 5'5"(157 - 166 cm) | 27.6" - 29.5"(70 - 75 cm) |
| 51 | 5'5" - 5'8"(164 - 172 cm) | 29.1" - 31.1"(74 - 79 cm) |
| 54 | 5'7" - 5'10"(170 - 179 cm) | 30.7" - 32.7"(78 - 83 cm) |
| 56 | 5'10" - 6'1"(177 - 185 cm) | 32.3" - 34.3"(82 - 87 cm) |
| 58 | 6'0" - 6'3"(183 - 191 cm) | 33.9" - 35.8"(86 - 91 cm) |
| 61 | 6'2" - 6'7"(189 - 200 cm) | 35.4" - 38.2"(90 - 97 cm) |
| Size | Height Range | Inseam Range |

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