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
13T solid pulleys and decreased derailleur tension prevent high chain tension in low gears
Alloy outer and inner pulley cage saves weight and increases rigidity
