Description

  • Shimano GRX, with its gravel specific ergonomics, optimized gearing options, rugged reliability, and quiet and stable drivetrain, sets itself apart from the rest of the component world

  • The integrated removable on-board battery is protected within the linkage
  • Crash recovery function, absorbs impacts and returns to its original position
  • Connectivity BLE, ANT private
  • 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
