BLACK BOOK 795 BLADE RS
ORIGIN DESIGNED & MANUFACTURED BY LOOK DESIGNED FOR PERFORMANCE 3S DESIGN - AERODYNAMICS - ERGONOMICS VERSATILITY SMART INTEGRATION - TT READY There was a time when aero road bikes only focused on aerodynamics, but this time has passed and the 795 BLADE RS is LOOK s iteration of a bike that fulfills all road cyclists dreams. The 795 BLADE RS cuts through the air, provides unmatched stiffness to weight ratio in the aero bikes category and it maintains traction where other bikes fail thanks to an innovative rear triangle design and large tire clearance. Rim brake and disc brake versions are available so that no matter which braking system the cyclist prefers there will be a 795 BLADE RS for him. In summary, the 795 BLADE RS is packed with so many features that assure it is the fastest, smoothest and most versatile bike LOOK has ever made.

CARBON CORE DESIGNED & MANUFACTURED BY LOOK Since LOOK s beginning in the bicycle world when metals were king, our material of choice has always been carbon. For over 30 years LOOK has developed in its own factories a unique expertise and a vast know-how in the carbon field to reach specific desired properties. Once the optimal shapes had been created, our engineers work on the processes and on the carbon lay-up for each areas of the bike in a very precise manner in order to achieve our goal : the creation of a super fast bike that is not only fast by being aerodynamic but also light and stiff, all while offering superb traction. Carbon lay-up for us is key, it s about selecting for each location the right fibers, right orientations, right thicknesses ( number of plys ), right reinforcements when necessary. For example, the bottom bracket area has to resist higher forces than the head tube does, the same goes for each part of the frame and fork, this is one aspect in which LOOK s expertise makes a huge difference.

We combine these fibres to optimize the different performance parameters : Stiffness - Weight - Traction. HR 8 % OTHER FIBERS 6 % HM : High Modulus «High-end» fibers. Their stiffness rating is very high, about double that of HR. These fibers are used wisely because they are more brittle. HM fibers allow added stiffness with the lowest weight penalty. HM 32 % 795 BLADE RS IM 54 % IM : Intermediate Modulus They have good resistance and fall somewhere between HM and HR of which they are a good complement. HR : High Resistance High resistance fibers are less stiff in elongation but can resist deformations and impacts better, they are very useful in high stress areas and also in areas where controlled deformation is beneficial to the ride quality of the bike. Other material like flax can be used in specific areas to further increase vibrations dampening.

DESIGNED FOR PERFORMANCE
TECH NO LOGY 3S DESIGN OPTIMIZE TRACTION TRANSFER 100 % OF THE POWER TO THE ROAD A fast bike is a bike capable of transfering the highest percentage of the cyclist s power to the road, creating forward motion. Our new 3S TECHNOLOGY is all about rear wheel traction. By creating longer and curved seatstays, having no bridge between them ( on both rim brakes and disc brakes version ) and optimizing the lay-up to allow some vertical movement while maintaining lateral stiffness of the rear triangle we give the cyclist not only traction but also comfort. One of the benefit of bringing traction and comfort in the rear triangle is that the bike does not rely on a flexible seat post, thus improving pedaling efficiency once again!
SMOOTH SWORD SEATSTAYS The seatstays of the 795 BLADE RS are engineered to deliver maximum efficiency. The lack of bridge between the seatstays and the arched seatstays shape allows the seatstays to bend under compression coming from the rear wheel axle. This allows the rear wheel to maintain a constant contact with the road thus ensuring maximum transfer of power, increased grip and control. BRIDGELESS REAR TRIANGLE ON BOTH RIM BRAKES AND DISC BRAKES VERSIONS
TESTING RESULTS The following test results show that the 3S seatstays without the brake bridge allows 20% more deformation that any other configuration tested.

TESTING RESULTS WEIGHT & STIFFNESS Weight and Stiffness are two essential parameters that bring performance and ride quality. The 795 BLADE RS provides high stiffness to weight ratio on a bike shaped for speed.the 795 BLADE RS offers pro rider the required stiffness in a lightweight package, which means that it will feel as good in a sprint finish as in a col in the Alpes, Pyrenees or Dolomites. Stiffness is optimized in each area giving the perfect ride quality for all riders. Our engineers go as far as making sure the stiffnesses on the frames and forks are adjusted for each and every size, making all riders enjoy the ride no matter how tall they are.

AERODYNAMICS
AERODYNAMICS AERODYNAMISM : CFD DEVELOPMENT LOOK was one of the first bike manufacturer to use Computational Fluid Dynamics software to optimize new bikes design. Now it seems a common thing, but you need a lot of experience to understand all CFD can do. Only an expert eyes can talk with the results of calculation. LOOK collaborates with one of the best Formula 1 Aerodynamicist in the World.
AERODYNAMICS AERODYNAMISM : WIND TUNNEL VALIDATION PROTOCOL Final validation testings took place in the new Flanders Bike Valley wind tunnel. This is a unique, independent, low speed wind tunnel designed specifically for cyclists and the cycling industry. A purpose-built wind tunnel can lead to higher overall accuracy and repeatability than the those built for aeronautics, aviation, motorsports, or other scientific research. All bikes with exactly same handlebar REACH and STACK, and same saddle height, saddle setback, tilt All bikes with two round bottles. The saddle is a Prologo Dimension Tyrox for all bikes. 795 RS 785 RS 785 RS DISC 795 BLADE RS 795 BLADE RS DISC SIZE M ADH2 AERO HANDLEBAR SHIMANO DI2 R9150 GROUPSET ( INCLUDING CRANKSET ) CORIMA WS47 GP4000S II TIRE SIZE M LS2 LIGHT HANDLEBAR SHIMANO DI2 R9150 GROUPSET CORIMA WS47 GP4000S II TIRE SIZE M LS2 LIGHT HANDLEBAR SHIMANO DI2 R9150 GROUPSET CORIMA WS47 DISC GP4000S II TIRE SIZE M ADH2 AERO HANDLEBAR SHIMANO DI2 R9150 GROUPSET CORIMA WS47 GP4000S II TIRE SIZE M ADH2 AERO HANDLEBAR SHIMANO DI2 R9150 GROUPSET CORIMA WS47 DISC GP4000S II TIRE

TESTING RESULTS The results are weighted using a Gaussian curve according to real wind recorded datas to calculate a «yaw weighted aerodynamic resistance», in Watts. This value equals the power a rider needs to ride the bike at 45 km/h. Lower means less energy consumed. Lower is faster.

BOTTOM BRACKET CONFIGURATION The 795 BLADE RS uses a BB386 pressfit aluminium bottom bracket interface. BB386 is the best pressfit solution that works with both 24mm steel axles ( SHIMANO, SRAM GXP ) and WIDE 30 mm alloy axles ( FSA 386 EVO, ROTOR, most of SRAM 30mm cranksets ). The choice of an aluminium sleeve inside our frame offers the best alignment and the best possible pressfit tolerances. We went even further by collaborating with TOKEN PRODUCTS in order to supply each and every 795 BLADE RS with threaded pressfit bottom brackets and its tools. TOKEN PRODUCTS Ninja threaded bottom brackets are made of aluminium with fusion PA+FIBRE in the pressfit areas. This insures that the bottom bracket is strong, aligned and runs smooth with very low friction, while the pressfit area made of PA+FIBRE will always be quiet. This bottom bracket configuration is designed all together to offer the cyclist the fastest, most silent and most reliable solution. https://www.tokenproducts.com/bottom-brackets/ninja
EASY ROUTING The 795 BLADE RS has been developped with cable integration and easy maintenance in mind. It is compatible with both mechanical and electronic groupsets and there are specific rim brakes and disc brakes framesets. LOOK ADS stem and 795 BLADE RS headset hide derailleurs cable routing on both versions. As for the brakes, the rim brakes version has cable routing from handlebar to front brake caliber for the front brake and handlebar to top tube for the rear brake, the main goal here being to keep brakes efficiency high and maintenance easy. On the other hand the disc brakes version allow the housings routing to be made through stem and headset just like for the derailleurs, allowing for an even slicker front view of the bike with the smallest frontal area. Adjusting stem height is made easy thanks for spacers with cable routing openings in the rear.
