Shimano Di2 wireless trickles down to Deore (oh, and XT)

Di2 XTR OTT? How about XT Di2 then? Or even Deore Di2? Big news day from Shimano.

Following rather swiftly after the release of Shimano XTR Di2 earlier this month, the Japanese giant has unveiled two more wireless drivetrains for mountain bikes (and some new definitely-not-wireless XT brakes).

Shimano XT M8200 Di2 press release:

SHIMANO Expands Wireless Mountain Bike Component Lineup with New DEORE XT M8200 Di2 Groupset

From the foundational moments in the early 1980s when DEORE XT first revolutionized mountain biking, SHIMANO brings fast and reliable shifting, a robust drivetrain construction, and refined braking systems to more riders with the latest introduction of DEORE XT M8200 Di2 components.

Following the recent launch of our flagship XTR M9200 race group, DEORE XT receives key technology and design cues from XTR, delivering a robust group designed to withstand the demands of real-world riding, and consistently redefining what’s possible on two wheels.

• Fully Wireless Di2 Platform – Redesigned Di2 system with fast, precise shifting in a wireless design.
• Robust Drivetrain Construction – Built to survive trail impacts for rider confidence.
• Intuitive Ergonomics – Controls with a natural fit and feel, plus added adjustability so you can focus on the trail ahead.
• Predictable Braking Control – Refined power application with consistent performance and modulation in a wider temperature range.
• Freedom of Choice – More component options and Di2 features that can be optimized for riders’ terrain, style, and performance needs.

Robust Drivetrain Construction

Capitalizing on technological advancements introduced with the XTR M9250 rear derailleur, DEORE XT M8250 features the new SHIMANO SHADOW ES technology with a low-profile wedge design. Like XTR, the stabilizer unit blends seamlessly into the body of the derailleur, eliminating edges so it glances off trail obstacles and avoids most rock strikes and impacts on the trail.

When the inevitable hits do happen, the derailleur absorbs the impact and Shimano’s automatic impact recovery function instantly returns the derailleur to its original position.

The DEORE XT M8250 derailleur also features a robust alloy cage, which differs from the carbon cage found on its XTR counterpart but does not limit performance.

Rear Derailleur Technology Features

• Low Profile Design – SHIMANO SHADOW ES technology delivers a wedge-shaped design that reduces the derailleur’s front-facing surface area and eliminates edges that could catch on rocks and roots.
• Automatic Impact Recovery Function – The derailleur absorbs trail impacts and then automatically resets the rear derailleur, ensuring continued performance.
• Super Strong Design – The rear derailleur body boasts a wide, well-braced linkage and solid pulleys to minimize debris entry and ensure durability.
• New Chain Stabilizing Technology – With SHIMANO SHADOW ES technology the dual spring design creates higher chain tension for better chain wrap and retention.
• Battery Protection – Tucked safely inside the rear derailleur body, the sealed battery won’t budge, even on rough terrain, but can still be easily removed for charging.
• E-MTB Rear Derailleur Option – The wired E-MTB RD-M8260 features a constant power supply from the existing e-bike battery, equipping the bike with FREE SHIFT technology for seamless shifting as you coast, and AUTO SHIFT for smooth, automatic gear changes while pedaling.

Powerful Braking System

DEORE XT M8200 delivers powerful and reliable braking performance and is offered in several brake setup options for different riding styles and/or needs. Utilizing a single brake lever BL-M8200, riders can choose between the more powerful 4-piston BR-M8220 caliper or the lighter weight BR-M8200 (post mount) and BR-MT805 (flat mount) two-piston caliper designs.

DEORE XT Brake Lever

The new DEORE XT M8200 brake levers feature Shimano ERGO FLOW technology and utilize the same pivot point as XTR M9200 for a more natural braking motion. Additionally, the redesigned SERVOWAVE track ramps power smoothly but quickly and with the updated caliper design, BL-M8200 delivers consistent power at varying temperatures.

DEORE XT brakes utilize the reformulated low-viscosity mineral oil introduced with XTR, which flows consistently through the system in a wider temperature range. The combination of these two ensures stable piston movement within the system, delivering consistent performance and smooth power modulation.

BL-M8220 – Brake Lever

• ERGO FLOW Technology
