The Ultegra Shimano includes an option with power meter and carbon wheels for disk ytubess
While the new Dura-Ace is designed for those cyclists who seek all possible competitive advantages, the new Shimanoes ultegra the application to the real world of all these technologies.The R8100 series shares the same DNA as the R9200 series, offering incredible performance in any situation, combining the principles of speed science to help cyclists achieve greater performance than ever.
Ultegra evolutions, such as Dura-Ace, can be divided into five development areas: change platform, control interface, brake system, transmission system and wheel system.
All about Shimano in Joanseguidor's notebook
ULTEGRA CHANGE PLATFORM
The Ultegra of Shimano R8100 shares the same DI2 platform that Dura-Ace R9200 to improve the speed of change. A su vez, la conexión entre pulsador y desviador es inalámbrica, consiguiendo en cualquier caso una fiabilidad absoluta.
The new Dura-Ace and the new Ultegra share the same platform, so Ultegra users benefit from:
The difference of ultegra deviators with respect to the Dura-Ace is in its construction.Front and rear deviators Dura-Ace R9200 weigh 215 g 96 g respectively, compared to the weight of the R8100 fivers of 262 g and 110 g.A 61 g difference.
Ultegra control interface
Para los puertos, los sprint o las contrarrelojes, el nuevo ULTEGRA consigue el equilibrio entre comodidad, diseño y ganancias aerodinámicas con una incomparable ergonomía.
The new hydraulic and wireless disc brake handles 2 × 12 speeds (ST-R8170) now have a higher tip with a slight curve inwards and a greater grip surface to offer better control and more comfort.This provides the cyclists for a better grip when they pedal with the index and thumb fingers in the area of the hand hoods and three fingers behind the brake lever, while offering easy access to the change lever when we gograbbed at the bottom of the handlebar.Now the DI2 buttons have separated laterally with respect to the brake lever, allowing a better differentiation between the change button to climb crowns and the button to lower them, especially with gloves or wet fingers.
The Ultegra St-R8170 change levers work with a wireless connection using CR1632 button batteries.This wireless connection makes the installation in the handlebar easy and without cables and gives us the possibility of having a much cleaner handlebar.
The ST-R8170 are compatible with the new remote exchange buttons.The Shimano Sprint button (SW-R801-S) or the mountain (SW-R801-T) can be installed with a clamp or can be integrated into handlers with a specific port, such as the new Pro Vibe Evo.These new more compact satellite buttons are connected in the curved area of the handlebars using a 100 mm cable (SW-RS801-S) or at the top by a 260 mm DI2 cable (SW-RS801-T).
La interfaz de control ofrece útiles opciones de personalización gracias a la actualizada aplicación E-TUBE que ahora es compatible con la serie Ultegra R8100.Like the previous versions, version 4.0.0 of E-Tube Project allows you to configure options such as synchronized or semi-incronized change, multiple change, exchange rate or the assignment of STI change button.In addition, we can connect and configure third -party cyclocomputer to show DI2 system information.
Again, due to small differences in construction, there is a weight difference of 32 g between the hard gear levers Ace ST-R9270 (350 g) and the ULTEGRA ST-R8170 (382 g) change levers (382 g) (382 g).
ULTEGRA TRANSMISSION SYSTEM
Ultegra has two new Hyperglide+ 12-speed cassettes with ratios of 11-30 and 11-34. El cassette 11-30 en particular se ha optimizado con una revisión en los engranajes del «punto óptimo» entre los piñones 6, 7 y 8 para mantener los cambios de marcha suaves y consistentes característicos de Shimano.
Si a esta combinación le añadimos cambios rápidos y suaves gracias a los perfiles en rampa inteligentes de los cassettes, conseguimos cambios de marcha más suaves, incluso en momentos de máxima carga y tensión, sin importar si se está subiendo o bajando piñones.
As a result, we get that there is no need to stop accelerating or looking for a softer pedaling when we change.Now cyclists can go thoroughly and change even faster, with a softer cadence and a better speed transition thanks to ultegra cassettes with Hyperglide+ technology.
The Ultegra cassettes come with a new striated pattern for installation, which is also compatible with the 11 -speed Shimano nuclei, which means that the new Ultegra R8100 components can be used in the previous 11 -speed Shimano wheels.
For the first time, the Ultegra connecting games come with the option of a power meter.The FC-R8100-P offers up to more than 300 hours of pedaling thanks to an integrated, waterproof and rechargeable battery.Pedaling data is obtained by means of shimano patented sensors installed in the two cranks.
ULTEGRA PATHERICES use Bluetooth and ant + technology to transmit data.
Stargy games with potentiometers and are potentiometers have 50-34t or 52-36T dishes configurations with connecting rod lengths of 160, 165, 170, 172.5 and 175 mm.The rod game with ultegra potentiometer weighs 716 g, which is savings with respect to the rod game with hard-ace potentiometer, more rigid, which weighs 754 g.
The Ultegra R8100 uses the same 12 -speed chain used in the Shimano XT M8100 group, simplifying inventory needs to stores and cyclists
Ultegra brake system
The new Ultegra brake components of Shimano offer a more precise control in the most closed, fast and aggressive curves you can find.With the incorporation of Servo Wave technology, already used in the brake systems for MTB and Graso in Shimano, the brake levers have a smaller route to the point of contact with the pill obtaining a more immediate touch and allowing a softer modulationOf the brakes, a faster drive and greater confidence in complicated situations.
In addition, the reduction in brake no. El resultado es un sistema más silencioso, gracias a una menor dilatación térmica del disco y una menor probabilidad de roces ocasionales entre disco y pastillas.
In addition, brake maintenance has also been improved.Now it is possible to purge the brake without removing the clamp (BR-R8170) of the box thanks to the fact that the traditional purple screw has been changed by a system in which we have separated the screw that regulates the bleeding and the hole through which theliquid.A new funnel and spacer also help improve the bleeding process.
The new Ultegra brake tweezers weigh 282 g the torque in front of the 233 g of Dura-ace.
ULTEGRA RING SYSTEM
The last pillar in the development of Ultegra is the point that unites the power developed by the cyclist with the speed.For the first time, Shimano has introduced a tubeless carbon brake wheel line at the ultegra level.
Like the new Dura-Ace wheels, the optimal performance is given by the balance between three factors: Reduction of wind resistance without sacrificing control, stiffness and lightness.All available in three “full carbon” wheel options and tubeless.
The three tire profile measures offer different benefits and performance levels for cyclists:
All new ultegra wheels have a tire profile just like the Dura-Ace, with an internal tire width of 21 mm.However, unlike the Dura-Ace, the Ultegra C36, C50 and C60 wheels use a standard 1: 1 radii pattern with 1.5 mm radios to reduce the weight.
Driving stiffness has been increased to increase power transmission when we accelerate.This has been achieved in the new ULTEGRA wheel C36 a 9% increase in stiffness compared to the current Dura-Ace C40-TL wheel.
Ultegra R8100
Shimano's study of speed science has led the development of road bicycles to a completely new level.The new handles, brake tweezers, wheel, deviators, cassettes and connecting rods, in addition to the new wiring and batteries di2 EW-SD300 of the Ultegra R8100, are a sample that Shimano spares no effort when it comes to reaching the next level in technologies thatallow us to reach maximum speed and that can be applied to the real world.
The complete component table shows the new products and the recommended compatibility with existing products.
Cyclists who choose Ultegra can immediately benefit from Dura-Ace design philosophy and many of their technologies to take their performance to a new level.
But don't trust our word.Try it yourself.Ultegra R8100 components will be available in stores from October 2021.
