Cervelo S5 Frameset - LTD Lupine

Cervélo S5 Frame – Extreme aerodynamics and pure speed for road cycling

The Cervélo S5 frame has been an absolute benchmark in the world of aero competition bikes for years. Designed to dominate the most important races on the international calendar, it combines aerodynamic efficiency, stiffness, and lightness in an iconic and recognizable design, chosen by the best World Tour professionals.

‍Uncompromising speed

The new generation of the S5 evolves an already winning platform, becoming:

• over 6 watts faster than the previous version
• 124 grams lighter
• even more stable and responsive

The result is a frame designed to maximize speed in every condition, from sprints to breakaways, up to time trials.

Advanced Aerodynamics

Every detail of the S5 has been developed to reduce air resistance:

• New fork and head tube with more pronounced profiles
• Total front integration to improve aerodynamic flow
• Asymmetric seat tube optimized with the rear wheel

Wind tunnel tests show an advantage of:

• 6.3 Watts compared to the previous model (at 30 mph)
• at least 5 Watts compared to main competitors

HB19 One-Piece Integrated Handlebar

The Cervélo HB19 monocoque carbon cockpit introduces the “Plus-Four” concept:

• top grip 4 cm narrower than the bottom grip
• more aerodynamic position uphill and on flat terrain
• greater stability downhill and in sprints

9 size combinations available, all compliant with UCI regulations, with the possibility of replacement within 60 days for a perfect fit.

Optimized lightness

Despite the increase in aerodynamic surfaces, the frame has been lightened thanks to:

• carbon layup optimization
• complete hardware overhaul

The result is a perfect balance between reduced weight, stiffness, and aero performance.

Integration with Reserve 57|64 Turbulent Aero wheels

Developed in collaboration with Reserve, the new wheels:

• are designed in the wind tunnel together with the frame
• improve airflow thanks to their asymmetric design
• guarantee +3 Watts advantage over the previous model

Professionals' choice

The Cervélo S5 has been a protagonist in the biggest international competitions, used by champions such as:

• Wout van Aert (Green Jersey, modern victory record)
• Simon Yates (Pink Jersey)

A symbol of speed and innovation in professional cycling.

A Complete Guide to Bike Sizes

Foreword: Not all bike sizes are the same

Each type of bike has a specific frame and often uses a different size scale. For example, a road bike with a 54cm frame might be considered a medium size by one brand, but a large by another.

Bicycle adjustment margins

Some types of bikes, like gravel bikes, offer a wide range of adjustments, adapting to different body types. Other models, however, have limitations in this regard. This is an important aspect to consider.

How to use size charts

We've created a simple guide to help you find the right bike size:

1. Check out our size charts for each bike type.
2. Learn more with specific tips to help you make the right choice.

Size Charts: Find Your Perfect Bike

Gravel and road bikes

Sizes are based on the length of the top tube (in cm), which determines the reach of the bike.

For gravel, measurements may vary slightly due to different geometries, but remain similar.

Mountain bike

MTBs are measured in inches, based on the seat tube.

Sizes also vary depending on the type of MTB: full-suspension , hardtail or fat bike .

Children's bikes

The size depends on the size of the wheels, often associated with age:

What to do with half measures?

If you are between two sizes:

• Comfort : Choose the larger size.
• Performance : Go for the smaller size.

Final tips for choosing

1. Consult the manufacturer's instructions : Always check the brand's guidelines.
2. Ask an expert : a specialized workshop can help you choose based on your height, ideal reach and goals.
3. Test the bike : If possible, test the model you intend to purchase.
