AVENGER is Shenzhenshihong Fu Sporting Goods Co., Ltd. launched its own brand, R8 is AVENGER brand's latest model, is a road with a large group of aerodynamic effect of the frame. The frame group handsome pneumatic price 6980RMB , but this test vehicle equipped with SHIMANO 6800 suite, DEDA 35 handlebar stem, UAM 56mm thick ring carbon fiber aerodynamic wheels and other price 16000RMB.
R8 Frame matte painting of red and black, simple lines, good texture, quite big brand style
R8 frame geometry. This time we received was 50cm frame
Marked on the frame tube TORAY symbol indicates the frame using a famous Japanese brand Toray carbon fiber
Hourglass-shaped tapered head tube has a good rigidity and can reduce frontal frontal area, less wind resistance.
NECO is a conical bowl set bowl set aside 20mm fork standpipe allows riders freely adjust the handlebar height on the height of the bowl lid assembly is 8mm, helps the drivers further down the neutral position, it is possible to obtain a greater before and after the gap.
And the most aerodynamic design road bike fork, like, R8 also has an aerodynamic straight tube fork.
As one piece full carbon fork fork fork pawl corner stainless steel safety shoes, anti-loose design the way Tucao about, first wife of titanium quick-release lever, although light, but the work is very general, thin and narrow handle, lock dead resistance, use up and feel jerky.
Frame into the line port compatible with mechanical / electronic shifting traces into line replaceable seat can accommodate different wire
Narrow and flat down tube connected to five, the five-way using a very traditional screw-BB. The five-way width is very traditional 68mm. Riser at promising Di2 electronic shifting reserved traces holes can be upgraded to facilitate future electronic gear kit.
Riser Tail aerodynamic design close to the rear wheel, it is possible to reduce the resistance of turbulence, smoother airflow through the frame and the wheel surface.
Drop-shaped riser certainly not escape the teardrop-shaped seat post design, the front seat post also increases the non-slip design, making installation and adjustment are very convenient .R8 seat tube clamp design is very concise, if you can find the same color technician Friends - electrical tape to cover the adjustment screw, it is generally difficult to find even a fixed position of the seat post.
Rear triangle design uses compression after the current most aerodynamic vehicles will use the triangle design, by reducing the length of the rear fork to reduce the frontal area. However, in order to reduce air resistance, after the fork tube design failed in the vertical deformation any achievements, so ride on a bumpy road after bouncing triangle significantly affect comfort.
But AVENGER does not compromise, you can see the fork after the junction of the lower fork and the rear there is a bent, this is the frame to add some vertical deformation, increase comfort.
Drive kit chosen Shimano 6800 mechanical transmission, dental plate specifications for 53-39T, leg length 170mm, after the use of flywheel 11-28T.
Wheel selection Hongfu Gong Division UAM 56mm high modulus carbon fiber Wide wheels, the pair of wheels weighs about 1700g (not including the weight of the quick release), rim at its widest point is about 26.5mm, the use of hubs and CN Taiwan CHOSEN breaking wind flat spokes establishment, it has a good aerodynamic performance Heping Road cruise performance.
Original car standard tire Vittoria Rubino pro 23C, training and general amateur racing just right
Handlebar selection DEDA TRENTACINQUE M35 and bend the stem
Most aerodynamic road bike will choose to use the wind to break the group to reduce the frontal area of the handlebar, but here R8 was chosen the most robust is the frontal area of the largest 35mm group, it is puzzling, do R8 is to shake the car to fight the last sprint?
The front frame is designed to install brake directly mounted front brakes use Taiwan TEKTRO straight mounted brakes, brake feel good, close to the 6800's feel and brake calipers force.
Rear brake using Shimano 6810 hidden clip. 'Hide' in the latter under the fork to reduce wind resistance, the rear brake is designed more popular road car aerodynamics.
Vehicle car AVENGER R8 road car is a moderate. I was to find the golden mean adjectives to express my feelings. Although the appearance quite fighting spirit, but at low speeds, R8 show some 'lazy' and the use of high-frame 56mm wheel set (fat circle), so this car R8 start acceleration performance is not satisfactory (the bottom frame with wheels start acceleration should be good, R8 through five coarse rigidity launch time will not crash force, like the force of the riders on the grid box mounted high wheel). mainly for the case of high power output of feedback slow stampede Also interesting is the standard crankset (53-39T) and 11-28T flywheel mix, although Cohesion is better 11-25T gear ratio so dense, but this car R8 is this mix there is help quickly pulled cadence to improve speed. for groups interested in buying R8 frame of riders this DIY is a very useful tips. inform the manufacturers is still the main sales group of the frame, the vehicle with the riders can follow their favorite DIY.
The low state is not satisfactory, but as a pneumatic R8 road car, its advantage is on a level road 35km / h + more speed range. Goes to high speed, 56mm high ring box car has a good rotational inertia, but the more popular wide circle design, R8 can better maintain the speed. R8 car at the front and rear wheelbase and rear fork length is rather long, favoring stable design, the actual performance, too, to 45km / h on the speed + , performance is still very stable. frame broken duct design is not very popular with crosswind influence, this is commendable.
But there were also another flaw, that is more than stable and flexible enough. My height is 180cm 50cm car ride of 'trolley', manipulate them still do not feel flexible, general road bending Fortunately, if you encounter a large angle corners understeer phenomenon occurs, it seems the best stage car R8 is straight road ah.
Also will look at the price of this car R8, 16000RMB price, you can buy a kit with SHIMANO 6800, DEDA 35 handlebar stem, UAM 56mm carbon fiber wheels, pretty good price. If you want to assemble their own a personalized car, R8 frame set is priced at 7000 yuan, 50CM frame weighs 1150g, be lighter weight aerodynamic frame large group. If you intend to buy a lightweight road pneumatic frame to assemble a large group of road vehicles with silver do not want to spend too much, then R8 frame groups can be included in your shopping list.
