Overview of Orbea Orca Aero and Cervelo S5

The Cervélo S5 is all about aerodynamic performance and maximizing speed.

This can be seen throughout the frame’s design. Most road cyclists would concur that the Cervélo S5 is among their top choice for an aero road bike. They come with 25mm tires, but the frame allows up to 30mm.

The Cervélo S5 has a very aggressive frame geometry, placing the rider much lower on the bike and reducing their frontal area. A size 54 Cervélo S5 has a 13mm lower stack and 6mm longer reach than a size 54 S-Series (discontinued in 2022). The Cervélo S5 has an extended seat tube cutout; a close-fitting curve in the seat tube fully shields the rear wheel’s leading edge.

The Cervélo S5 is available in a complete bike setup or frameset only.

The Orbea Orca Aero combines the design principles of the Orca Orca road and the Ordu time trial bike. It uses Toray’s T1100 monocoque carbon, which Orbea refers to as OMX carbon.

The most obvious and standout feature of the Orca Aero is the aero water bottle and storage box beneath the down tube. They are optional and can be removed, depending on your preferences.

The Orbea Orca Aero offers you a lot of customization options from frame color, groupset, wheelset, tires, and saddle using the MyO configurator. There are 6 models available with either Shimano or SRAM electronic shifting groupsets.

Cervelo vs Orbea carbon fiber

Cervelo Carbon

Cervelo doesn’t publicly release information about the types of carbon fiber used on their road bikes.

From my observation of the current Cervelo bikes lineups, there are at least two carbon fiber grades used.

  • Highest grade. Cervelo R5 and S5 could be using the highest carbon fiber grade of all the models. These are pure race bikes used by the pros and would likely have the best carbon fiber available at Cervelo.
  • Mid-grade. Cervelo Caledonia and Soloist could be using a mid-level carbon and heavier fiber grade of all the models. These are endurance bikes that prioritize comfort over stiffness. So it’s not a surprise to see a lower-grade carbon fiber being used here.

Orbea Monocoque (TorayCa) Carbon

Orbea uses carbon fiber from TorayCa in their bikes. It’s one of the handful of bike manufacturers that uses a monocoque carbon fiber construction, resulting in a lighter and stiffer frameset. The two most prominent types of carbon used in Orbea’s bike frames are OMX (T1100K) and OMR (T800) carbon.

  • OMX (Orbea Monocoque X) carbon is Orbea’s top-grade carbon fiber, with the ultimate blend of stiffness, lightness, and strength. Monocoque refers to a type of construction technique where the external skin supports the structural load, which, when applied to bike frames, results in a balance of strength and weight. Due to its high manufacturing cost, OMX carbon is typically reserved for Orbea’s top-tier models.
  • OMR (Orbea Monocoque Race) is the standard carbon composite used by Orbea. While OMR doesn’t match the absolute performance capabilities of OMX, it offers a fantastic performance-to-value ratio. This makes it a great choice for riders looking for top-notch performance without the premium price tag of the top-grade OMX carbon.

Frameset technologies and innovations

Orbea Orca Aero and Cervelo S5 framesets incorporate advanced technologies to enhance their bikes’ performance and ride characteristics.

Here’s an overview of the technologies used in each bike model.

Cervélo S5

NameDescription
V-stemThe V-stem was launched in 2018 with the previous generation S5. It was controversial at that time as there was nothing like that on the market before.

Cervélo wanted to route the shifting cables and brake hoses internally, but the bend between the handlebar and stem could have a negative effect on mechanical shifting performance. Hence, the Cervélo engineers designed a V-shaped stem to minimize the bend.

Today, the Cervélo S5 is available only in electronic shifting builds, but the V-stem design remains. It’s now part of the S5’s identity.
HB14 carbon handlebarThe HB14 carbon handlebars are designed specifically for the S5’s V-stem. It’s available in 380, 400, 420 and 440mm.
34mm tire clearanceThe tire clearance for the S5 is a massive 34mm, which is very wide for an aero bike.

Orbea Orca Aero

NameDescription
Monocoque Carbon ConstructionMonocoque carbon construction is a process that uses the most advanced carbon technology to create the most sophisticated bike frames possible. Monocoque means that the frame is made of a single piece of carbon fiber, rather than multiple pieces joined together. This ensures that the frame is lighter, stiffer, and stronger, as there are no weak points or excess material.

Orbea has two grades of carbon fibers; OMX (Orbea Monocoque X-Light) and OMR (Orbea Monocoque Race). Orbea also uses a bladder molding technique with EPS (expanded polystyrene) forms and PU (polyurethane) inserts to prevent wrinkles and gaps in the carbon layers, which can compromise the quality and durability of the frame.
TrueAeroTrueAero is a combination of shapes, sizes, and materials that optimize airflow across the entire bike. TrueAero carbon is used to construct the Orca frame, which is designed to reduce drag and increase speed. TrueAero also includes features such as an integrated stem and handlebar, hidden cables, and an aero seatpost.
ICRThis stands for Internal Cable Routing, which is a system that routes all the cables neatly through the bar, stem, and headset for a clean look and improved aerodynamics. ICR also makes it easier to maintain and service the bike compare to other bike brands’ solutions.
