The result of 10 years’ R&D
- Lightweight and aerodynamic road bike
- 2 versions available: AEROLIGHT (integrated brakes) and LIGHT (conventional brakes)
Integration pushed to the limit: Aerostem, new E-Post 2 seatpost, brakes, Zed 2 crankset, HSC8 fork
Ultra-light 1.5K carbon fabric
30 years of experience in carbon and 10 years of experience in specific research conducted by our design department have made it possible today to introduce you to the most aerodynamic road bike ever built: the 795 Aerolight.
With its 11 patents, it is without doubt the bike that embodies the most technology. New 1.5k carbon frame with NACA* aerofoil section tubes, Aerostem carbon stem, ZED2 one-piece carbon crankset, new E-Post2 with Di2 battery mount, 100% integrated cable routing… all parts of the 795 Aerolight have been designed down to the last detail to offer you this extraordinary machine.

• LIGHTWEIGHT AND AERODYNAMIC ROAD BIKE
The 795 is one of this new generation of bikes that pushes the performance envelope even further. In addition to the qualities to be found on high-end bikes such as efficiency, light weight and comfort, the 795 boasts an additional advantage: aerodynamics. The many integrated features boasted by the 795 and increasingly precise carbon compositions mean that it is possible to build an aerodynamic road bike today without increasing weight. The 795 weighs the same as the highly efficient and renowned 695 while achieving much better aerodynamics. A complete bike can therefore happily keep within the 6.5 kg limit. In order to achieve truly improved aerodynamics, all tube sections have this teardrop shape (see diagram below) that reduces turbulence behind the tubes and helps maintain high speeds. Not only the seat tube and down tube, but also the head tube, fork and stays have been designed with this shape known as the NACA aerofoil, validated by aerodynamics engineers then wind-tunnel tested.
• INTEGRATED AEROSTEM
The 795 boasts fully integrated carbon AEROSTEM.
This stem is made of carbon, it is very light and above all it boasts aerodynamic properties since the traditional cap is replaced by a clamp. Advantages: the clamp screws are “concealed” behind the handlebar and the clamp is very thin. This feature, combined with a more fluid design, endow this stem with a better drag coefficient, hence its name: AEROSTEM.
Combined with the 795, it represents the best possible integration. In actual fact the adjustment range remains very wide: from + 17° to -13° which equates to 57 mm of adjustment for a length of 110 mm without hindering the integration.
• BRAKE INTEGRATION
The 795 is available with or without integrated brakes. In the version known as “AEROLIGHT” both sets of brakes are integrated, in the “LIGHT” version the brakes are conventional, i.e. located in front of the fork and at the top of the seat stays.
The front brakes on the 795 Aerolight, of the mechanical V-brake type, are located centrally in the fork legs in a housing that forms a window. This means that the calliper is fully concealed within the fork in order to achieve the best possible aerodynamics. The brake cable and sheath follow an exclusive routing since they enter under the stem to be routed inside it and “drop down” inside the steering tube to operate the calliper. External fitting is also possible however and the calliper may be operated from the left or from the right. The rear brakes are the Shimano Direct Mount standard, they are located under the chain stays and also feature integrated cable routing through the down tube and under the bottom bracket shell.
• NEW EXCLUSIVE 100% INTEGRATED ROUTINGS
With the focus still on aerodynamics, mechanical and electrical cables on the 795 are routed in an entirely new way. The cables are collected at the front of the head tube so as to bypass the bearings and be distributed inside the frame. The rear derailleur cable emerges behind the hanger, and for an electronic configuration even junction A, which is usually housed under the stem, is built into the frame, behind the stem.
Note: on the AEROLIGHT model, the front brake cable can be routed either internally, in which case the sheath passes through the stem and the steering tube, or externally. In this case the sheath operates the front brakes from the outside either on the left or the right-hand side.
• NEW E-POST 2 SEATPOST
This new seatpost has been developed by retaining all the benefits of the first version: vibration absorbed through elastomers, anti-rotation, adjustable. Moreover it is more aerodynamic, 29% lighter (just 139 g!) and easier to adjust thanks to an all-new fixing system: all it needs is ½ a turn to lock or release it. Furthermore it is compatible with Monlink type saddles and standard saddles.
• HSC 8 AERO FORK AND HEAD FIT 3 HEADSET
It is 100% one-piece carbon and weighs only 320 g in its aero version and complies with standard EN 14781 (144 joules frontal impact).
The tapered steering tube uses the CFD (Continuous Fibre Design) concept and enables the bearings to be located directly on the fork crown (oversize for 1½ inch bearings). The steering tube has 2 flats and is reinforced to take the Head fit 3 headset, dissociating headset adjustment from stem tightening. The headset’s adjustment is done by tightening the carbon ring on an offset thread locked onto the steering tube. It is now possible to change stem height without altering headset adjustment.
This arrangement does away with the compression kit, replaced by a simple cap. Weight savings: 40 g The 3rd generation of the Headfit is completely integrated into the head tube even further optimising steering precision.
• ZED 2 ONE-PIECE CARBON CRANKSET
The ZED 2 carbon crankset included with the 795 Aerolight is a highly innovative model :
It is moulded in a single piece of carbon (2 pedal cranks + axle + spider = ONE-PIECE THROUGHOUT).
It achieves a previously impossible rigidity / weight ratio. The crankset alone (less bearings and chainrings but including the two cranks and the spindle) weighs just 320 grams!
Its special Z shape enables it to be fitted to the frame that has a special oversize bottom bracket shell (bearing diameter 65 mm). The technology in the three-lobe insert at the end of the cranks enables crank length to be varied between 170, 172.5 and 175 mm without replacing the crankset while maintaining compatibility with all pedals in the market.
• COMPRESSED DROPOUTS
Dropouts are compressed directly when moulding chain stays and seat stays. We thus obtain a ‘chain stays/wishbone/dropouts’ rear one-piece unit: better weight / reliability ratio.
• NEW ULTRA-LIGHT 1.5 K FABRIC
