Shadow ES features a super low profile skid plate design and optimized slant angle for optimal clearance

Shadow ES uses a dual spring chain stabilising switch that when on will reduce chain bounce in rough terrain maintaining more stable drive and shifting

The Shadow ES system is also zero maintenance and has no degradation of performance

Unique structure using two springs has a tighter chain wrap that improves shifting and security with increased spring force by 70%, allowing the chain to mesh firmly with the sprocket

With the tighter chain wrap skipping is prevented even as the cogs wear

Compact drive GS mech offers more ground clearance (-23mm) whiles also saving weight

13T solid pulleys and decreased derailleur tension prevent high chain tension in low gears

Full carbon fibre outer pulley cage saves weight while alloy inner cage increases rigidity

Cold forged wide alloy links and pivot body

Four fluorine-coated link pin bushings

Specifically designed to work with 12-speed drivetrains
