Shimano ULTEGRA Di2 8100 12S Disc groupset
The world's most revolutionary drivetrain system
Shimano has adopted a 100% performance-focused approach to make the new ULTEGRA groupset even faster. Whether you're competing in local races, beating your personal best, or sharing the pure pleasure of riding with friends, the new 12-speed road groupset offers unparalleled control and comfort, all day, every day. This sets Shimano apart from the competition. The revolutionary HYPERGLIDE+ technology lets you tackle climbs, sprints or simply train without having to think about the next gear change. The new Di2 shifting system uses exclusive wireless technology to deliver the fastest and most precise shifting on the market. And best-in-class battery life too, the internal centralised battery offers around 1000km of worry-free riding on a single charge.

Technologies
E-TUBE
E-TUBE is Shimano's “service” that uses websites or apps to maximize the enjoyment of riding a bicycle by connecting the riders, the bicycles and Shimano.
HYPERGLIDE+
The heart of this new groupset is the revolutionary HYPERGLIDE+ shifting technology. First introduced on Shimano MTB groupsets, this unique interface between chain and cassette gently guides the chain up and down the cassette for fast and precise shifting in both directions, even under extreme pedalling loads. So there is no longer any need to reduce pressure on the pedals before shifting. HYPERGLIDE+ ensures smooth and efficient shifting, every time.
HOLLOWGLIDE
Highly rigid hollow structure reduces weight while maintaining the same rigidity. More efficient power transfer and more immediate and precise chainring.
HOLLOWTECH II
The concept of HOLLOWTECH II technology is focused on producing a superior crankset which will maximize a rider’s power transfer. The rigidity of the crankset ensures pedaling efficiency while its weight, a key element of the crankset, you want light, aids in cycling longer distances over which the rider needs to pedal more. HOLLOWTECH technology is an ultra-lightweight hollow crankarm created by SHIMANO with the company’s own proprietary forging technology that also maintains rigidity. The addition of HOLLOWTECH II technology integrates the bottom bracket axle with the right crankarm for more stiffness and a weight savings to achieve a high-dimensional balance. Its outboard bottom bracket bearing system provides better weight distribution and more pedaling stability, allowing for more efficient power transfer.
