LinkGlide

Shimano LinkGlide sets a new standard for smooth and reliable shifting. Its robust original design delivers far greater durability and smooth shifting for long-lasting performance.

LinkGlide delivers Long-lasting performance:

3X More Durable

Drivetrain durability is essential for high torque e-bikes and daily riders who might ride in the same gear for months or years at a time. LinkGlide provides smooth and decisive shifting that lasts longer than ever before.

LinkGlide's re-designed cassette teeth have a substantially thicker base and a unique chamfer that drastically improves wear resistance in high torque applications. This increase in cassette durability prolongs smooth driving performance and lengthens the amount of time before chain skips caused by wear start to happen.

A major advantage of the LinkGlide platform is that the robust teeth shape provide excellent durability and improved wear resistance. This is very important because riders who often buy bikes at this level, choose bikes with gearing but may forget to shift or maintain their bikes as often as they should.

3X Smoother

LinkGlide provides smooth shifting while pedaling for a consistent and confident ride experience. LinkGlide's optimized gear gate design makes shifting smoother with significantly less shock.

LinkGlide delivers up to three times smoother performance by improving the chain's flow between cogs. This smoother handoff reduces the stress of shifting shock for more seamless and enjoyable riding.

LinkGlide's optimized shifting gate design that creates a smoother handoff between cogs to avoid the jumps that can impact shifting and pedaling smoothness. This design improvement is especially pronounced on outward shifts where pedaling shock is more noticeable due to the larger forces involved.

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.

Di2 Technology

Thanks to its lightning-fast, accurate, and reliable shifting performance, Di2 puts riders in complete control and ensures a seamless interface between the cyclist and bike like never before. Creating and continually improving the world's best shifting is a complicated undertaking requiring constant technological advancements. From hardware to software, Shimano Di2 technology is on the cutting edge, striving to deliver the best rider experience possible now and in the future.

Comprised of small junctions, wires, batteries, and mechanical units, Shimano Di2 looks and feels like a simple system, but it's packed with intricate functions and leading-edge technology. The Di2 platform is complex with many important pieces that must work seamlessly together to achieve Shimano's hallmark precise shift action.

Mechanical units - The small Di2 mechanical units in the front and rear derailleurs precisely control the movement of each derailleur to provide a perfect, crisp shift every time. The powerful, lightweight motors deliver faster and more reliable shifting in all conditions and all terrain.

Features

• Auto Shift uses an advanced shifting algorithm to continually analyze data from multiple sensors to automatically put you in the optimal gear without requiring manual input at the shifter
• Free Shift allows you to select the optimal gear while coasting into switchbacks or dynamic terrain changes, so you're always ready to charge with better balance and control
• Programmed automatic motion at the touch of a switch makes this derailleur quick, smooth and effortless to shift
• The removal of traditional mechanical cables in favour of electrical wires not only eliminates poor shifting caused by contaminates, corrosion and stretching
• Using Shimano's shadow plus technology and lowest profile to date, the M8150 will help you squeeze through the narrowest of trails without worry
• Derailleur contains a saver (fuse) function, where the inner structure is protected from strong impacts
• Aluminium pulley plates for weight saving and durability
• Specifically designed to work with 11-speed LinkGlide cassette and drivetrain
• E-tube SD300 Di2 wire compatible

Specifications

• Max Low Sprocket: 50T
• Total Capacity: 39T (Di2 System Limited)
