Digital Integrated Intelligence

Electric drivetrain with the best of brains and brawn.

The revolutionary DI2 shifting system solves the challenges drivetrains present to the power-delivery equation in cycling. DI2 gives you instant, accurate, lighting-fast shifts the first and every time, at the push of a button. Even in the most extreme conditions, shifting is precise and controlled. You can change gear even under heavy load while climbing or accelerating. With DI2, you are in complete control.

Providing the best balance of stiffness, strength, weight and rotating performance

HOLLOWTECH II technology is focused on producing a superior crankset which maximizes a rider’s power transfer. A rigid crankset ensures pedaling efficiency while light weight aids in cycling longer distances with less effort.

Balancing these demands led SHIMANO to develop HOLLOWTECH, an ultra-light, hollow crankarm that uses the company’s proprietary forging technology to maintain rigidity. HOLLOWTECH II takes the technology a step further by integrating the bottom bracket axle with the right crankarm for increased stiffness and weight savings.

Stay cool under pressure with Shimano ICE-TECH brake technologies. Designed to dissipate brake heat and provide the most consistent, reliable, and quiet braking available, ICE-TECH helps increase rider confidence, whatever the conditions.

ICE TECH’s 3-layer rotor construction of stainless steel and aluminum results in a 100-degree Celsius reduction in heat compared to standard rotors. This works together with thermal insulating pistons in the calipers and radiated fins on the pads to further reduce the heat of the rotors and brake fluid while also extending pad life.

Shimano SIL-TEC Chain Technology

Amidst all the technological wizardry of modern drivetrains, it’s easy to overlook one of the most important components of the group. The chain keeps the drivetrain running smoothly, overseeing the transfer of power while holding the system together. Much more than just the connection between the cranks and the cassette, the chain is a perfect loop of interconnected links, each performing with equal amounts of strength and precision.

Shimano boosts chain performance by using an ultra-low friction surface treatment called SIL-TEC to its top tier chains. This process involves applying imbedded fluorine particles to the chain using an advanced plating process that is superior to the simple coatings used in other chains. The benefits of SIL-TEC are significant to the performance of your chain and lead to a better ride experience from start to finish.

SIL-TEC delivers increased water and dirt resistance, which means the chain remains cleaner and dryer in all riding conditions. This enhances drivetrain efficiency, improves shifting performance, and allows the chain's lube to last longer with little interference from the elements. Additionally, SIL-TEC sheds mud 30% more effectively than chains with common Zinc-Nickel (Zn-Ni) plating treatments so riders can focus on the trail ahead and shift with confidence in all conditions.

Shimano SIL-TEC chains also help reduce friction in the drivetrain thanks to the slippery surface treatment. Chains that glide better over the chainring and cassette teeth are more efficient, so less energy is wasted in the mechanical process, and more power is transferred through the drivetrain. This means riders can use less energy and ride faster.

The SIL-TEC treatment also increases a chain’s lifespan, especially when riding in mixed conditions. The slippery, efficient chains accumulate less wear and tear as they glide across the drivetrain so they stay newer longer. Chains with SIL-TEC are 20% more resistant to abrasion and will help keep your entire drivetrain running smoother for longer.

Each feature of Shimano’s SIL-TEC treatment contributes to a bike that pedals smoothly and quietly, which riders will enjoy each time they ride. In quantitative terms, SIL-TEC brings a reduction in chain noise of -2.7 decibels thanks to a 60% reduction in rotation-based sliding friction. That’s smooth silence you can hear and feel.

Shimano uses its SIL-TEC surface treatment on many top-tier products, including XTR mountain bike chains and Dura-Ace road chains. Often an afterthought on spec sheets and in riders’ minds, the chain is actually a massive effort of engineering and manufacturing. It’s an integral part of any drivetrain and is one of the easiest and most cost-effective upgrades you can make for your bike.


Born from decades of precision-engineered drivetrains, HYPERGLIDE+ is the latest iteration of Shimano’s premium shifting technology. Now available on DURA-ACE and ULTEGRA 12-speed road cassettes, HYPERGLIDE+ lets riders shift smoothly and securely up and down the cassette without letting off the gas.

HYPERGLIDE+ is made up of two linked elements. Advanced shift ramps in the cassette combined with extended inner plates on the chain deliver maximum efficiency and incredibly smooth shifting performance virtually anywhere.

Never hesitate to shift throughout your ride knowing that HYPERGLIDE+ has the unique ability to perform any gear change, anytime you need it.
