TECHNOLOGIES:
SHIMANO SHADOW RD
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. The derailleur also sits 11mm further inboard compared to a conventional rear derailleur which reduces the risk of impact damage.
LINKGLIDE
3X more durable, 3X smoother....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. 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 also 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.
