Shimano Deore XT FD-M8000 Front Derailleur

Triple chainring 3x11 speed drivetrains have never been more refined. The Shimano Deore XT M8000 illustrates this beautifully with a Side Swing design, increased shifting power, and a sophisticated chain guide. They are offered in a variety of mounting options.

Technology

Dyna-Sys 11

Rhythm and range, the real advantage of 11-speed is the ability to have all the range you require without sacrificing the rhythm you need.

Range Optimized Chainwheels

Chainwheels matched with specific sprockets for:

• Improved gear quality and driving efficiency
• Reduced cross-chain
• Effective gear steps
• Larger diameter, longer wearing cogs

At the range

Driving: gears are purpose matched to keep you riding efficiently without front shifting

Climbing: gears are chosen to compliment the lowest cogs and maximize seated traction

Driving range

Dyna-Sys 11 maximizes rhythm with “rhythm step” gears in the most frequently used range.

• Less front shifting thanks to optimum front gear teeth
• Rider controls cadence and energy use by rear close ratio

Highly Efficient gear combination

Driving efficiency is a key drivetrain performance indicator.

• More speed for the same effort
• Multiple front gear (2x, 3x) maintains higher efficiency in all range

Gear Ratio

M9000 series

Front double 36-26 Tooth, Cassette sprocket 11-40 Tooth / Front single 30 Tooth, Cassette sprocket 11-40 Tooth

Side Swing Front Derailleur

Horizontal movement follows the chain direction - smooth & efficient front shifting effort

More tire clearance for larger wheels

• No linkage behind seat tube
• Freedom to reduce chainstay length

50% more powerful outward shifting (FD-M9020)

Wider chainstay angle increases traction range (FD-M9020)

HG-X11 Chain

Silky driving, accurate shifting HG-X11 directional chain realize more smoother shifts and greater overall performance.

Right and left sides are optimized for front and rear shifting respectively.
