Technology
LinkGlide Shifting Technology
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:
3 Times 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.
Shimano Shadow RD
The mechanism rear derailleur, Shimano Shadow RD, is intended for more aggressive riding. Its super low profile design carries many benefits. Because of its low profile and single tension construction, the derailleur does not hit the chain stay in rough riding conditions. The result is smooth and silent performance.
