Design Features

Each Cervélo bike combines select Design Features- technologies created by our engineers to further the performance of the bike across five key attributes: aerodynamics, weight, stiffness, ride quality, and usability. All are engineered to make the one difference that matters: a difference you can feel.
Feature / 1 of 22

BBright™

Cervélo developed BBright™ to take advantage of the fact that oversized frame tubes are stiffer and lighter. With the BBright™ system, larger-sized tubes are used in the seat tube, down tube, and left-hand chainstay. The benefit is increased stiffness and pedaling efficiency in a lighter weight frame. BBright™ is compatible with all major crank standards.

Squoval™

Squoval™ is a library of tube shapes that combine the attributes of a square with an oval. The shapes and sizes of these tubes enable our engineers to achieve the ideal balance of stiffness, weight, and comfort.
Feature / 3 of 22

Squoval™ Max

Squoval™ Max tubes are a library of tube shapes that combine the attributes of a square with an oval but with a more aerodynamic leading edge. With these unique shapes, we dial in the ideal balance of stiffness and weight in specific areas of a frame, while reducing aerodynamic drag.
Feature / 4 of 22

Squoval™ IPC

Squoval™ IPC tubes use the same general shapes as our classic Squoval™ tubes but move the fore-aft surfaces closer to the neutral axis to provide improved in-plane compliance. In terms of the riding experience, this makes the frame feel more comfortable, without negatively affecting its lateral stiffness or weight.

Pro Fit Road

Cervélo's Pro Fit offers our lowest frame stack heights to enable an aerodynamic riding position. The Pro Fit is the direct result of input from our pro racers who wanted to get their handlebars as low as possible for maximum aerodynamic advantage.
Feature / 6 of 22

Elite Fit Road

Our Elite Fit is based on extensive observations and analysis of riders' positions. It offers a wide range of positions for all athletes, from endurance riders to Pro-Tour racers, without compromising handling, comfort, or performance.
Feature / 7 of 22

Endurance Fit

Our Endurance Fit prioritizes comfort and stable handling. A shorter frame reach and higher hand position create a more upright riding position, ideal for long days in the saddle.
Feature / 8 of 22

Triathlon Fit

All of our triathlon bikes offer maximum adjustability for the largest possible fit range. Our Triathlon Fit accommodates all athletes' needs, enabling a range of fits from an upright torso angle to the lowest, most aerodynamic position.The details of the total fit range for each of our triathlon bikes can be found on the individual product pages.
Feature / 9 of 22

TrueAero™

TrueAero™ combines specific tube shapes, sizes, and design features to improve aerodynamic flow across the bike. The application of TrueAero™ is tailored specifically for each of our bikes and their intended uses.
Feature / 10 of 22

Speed Riser

The Speed Riser (patent applied for) is our user-friendly aerobar system for triathlon bikes. The aerodynamic single riser post is easily adjustable to an infinite range of positions with a single tool. This means that you can fully customize your fit, as well as make on-the-fly adjustments to your position.
Feature / 11 of 22

Extended Seat Tube Cutout

Our Extended Seat Tube Cutout is a close fitting curve in the seat tube, which fully shields the leading edge of the rear wheel to significantly improve aerodynamic performance.
Feature / 12 of 22

Partial Seat Tube Cutout

Our Partial Seat Tube Cutout is a shorter version of our Extended Seat Tube Cutout, providing improved aerodynamic performance at a lower cost and with a different look.
Feature / 13 of 22

Integrated Storage

Integrated Storage enables you to store your essential food, hydration, and service items so that they are easily accessible yet do not compromise the aerodynamics or structure of your bike. The built-in storage systems provide a simple and clean-looking solution to storage.
Feature / 14 of 22

Modular Storage

Modular Storage incorporates custom Cervélo parts and approved aftermarket accessories to allow full customization of your storage needs. It enables a secure and aerodynamic solution tailored specifically to your needs and your Cervélo bike.
Feature / 15 of 22

Aero Cable Management

The Cervélo frame, fork, handlebars, and associated components are designed to hide brake and shift control lines (mechanical, electrical, and hydraulic) from the wind for improved aerodynamics, without sacrificing usability or performance.
Feature / 16 of 22

Floating RDH

Our two-part floating rear derailleur hanger is designed to allow for easy alignment of the rear dropouts, ensuring that the rear axle can be installed quickly and simply every time. This design also incorporates the rear derailleur hanger and comes in different versions (threaded, RAT style) allowing you to easily update your frame and fork if standards change.
Feature / 17 of 22

Removable FDM

Our bolt-on front derailleur mount is made from high strength aluminum alloy and attaches to the frame with two countersunk screws. This allows for easy replacement in the event of damage, but also enables you to adapt to new standards as they become available or remove the front derailleur mount completely if you choose a 1x system.
Feature / 18 of 22

Cervélo RAT

Our version of the Focus RAT quick release thru-axle system is a game changer in axle design. The 1/4-turn design makes wheel changes a snap, and is easier and faster to use than a standard quick release or other threaded thru-axle designs. Clear markings on the axle and lever ensure safety, and a simple knurled dial allows for easy preload adjustment. The 12mm thru-axle works with industry standard road hubs.
Feature / 19 of 22

SmartWall™

SmartWall™ is Cervélo's patented method of distributing carbon composite material to the inner sides of frame tubes, improving stiffness, strength, and compliance while minimizing weight.
Feature / 20 of 22

Dropped Down Tube

Dropped Down Tube moves the upper part of the down tube closer to the front wheel. A cutout in the lower edge of the down tube provides wheel and tire clearance and helps smooth out the airflow between the front wheel and down tube, reducing your aerodynamic drag.
Feature / 21 of 22

Split Base Bar

Our Split Base Bar (patent applied for) allows for easy, stress-free packing and transport of the P5X. It lets you pack your bike without having to remove your brake, stem, or fork.
Feature / 22 of 22

CS28 Stem

The CS28 Stem (patent applied for) is a V-shaped stem which offers unrivaled aerodynamic performance, as well as full internal cable routing, ease of assembly and adjustment, and high stiffness. It is designed to partner with our separate aero road bar system. The shallow bend angles of the CS28 Stem reduce the curving of internally routed cables, eliminating pesky shifting problems.
