Product Description:

Ultegra R8100 – Leave Time Behind

When developing the Ultegra R8100 series, Shimano took a holistic and 100 % performance-oriented approach, because great speed means great responsibility. Faster than ever before, the 12-speed road groupset scores with unparalleled control and comfort anytime and anywhere – whether in an everyman race, on the hunt for a personal best time or on a companionable ride.

As with the Dura Ace R9200, not only does Hyperglide+ make its way into the Ultegra's components, also its Di2 parts rely on Wireless technology to simplify operation and ensure smooth shifting.

Shimano Ultegra FC-R8100-P Powermeter crankset

Integrated power capture at an attractive price. The Shimano Ultegra FC-R8100-P Powermeter crank is in no way inferior to its Dura Ace counterpart in terms of functionality and precision.

The integrated Powermeter sets standards in terms of performance measurement with an optimised accuracy of ±1.5 %. It measures the cadence data and the resulting values on both sides, that means independently for the left and right leg. Thanks to its design, the data collection is also free from external influences such as incline, road surface or wind. 

As the central element of the 12-speed drivetrain of the Ultegra R8100 series, the crankset is characterised by the shifting quality and transmission efficiency typical of Shimano. Not only the chainrings which feature a Hollowglide construction, but also the lightweight crank arms which are manufactured using Hollowtech II technology, contribute to optimised power transmission as well as faster and more precise shifting operations. All this adds up to a perfect balance between stiffness, stability, light weight and rotational efficiency.

Various crank arm lengths and chainrings with 50-34 or 52-36 teeth also offer variability and an optimal gear ratio for almost every riding situation.

Powermeter specifications:

• accuracy: ±1,5 %
• force measurement: left + right, 24 strain sensors
• cadence measurement: via magnet
• connectivity: Bluetooth / ANT+
• ports: 1x EW-EC300
• battery type: Li-Ion
• battery life: approx. 300 hours

Hollowtech II

The guiding principle of Shimano's Hollowtech II technology is the perfect balance between stiffness, stability, weight and rotational efficiency. The goal was to produce a crank that minimises the effort required for the drive and enables more efficient power transmission.

An exclusive forging process allows the production of extremely light crank arms that nevertheless guarantee maximum stiffness. The fixed connection of the right arm to the axle of the bottom bracket and its external bearing also serve an optimum relationship between stiffness and low weight.
