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 HollowTech II 11-speed single chainset offers optimum gearing for mixed terrains and riding styles Designed to work with HollowTech II type bottom bracket cups Compatible with 11-speed HG chains Anodized aluminium crank arms Lightweight aluminium chainring 4 arm, 110 mm bolt circle diameter Weight: 644 g (40T), 656 g (42T) for 170 mm
Features:High performance 11-speed Dyna-SysII cassetteHyperglide sprockets have a computer designed tooth configuration with contoured shift gates, resulting in a crisp smooth shift even under loadClose ratio gearing allows a more efficient use of energy through finer cadence controlLargest sprockets are mounted on lightweight alloy carriers to reduce weight and increase rigiditySprockets are cut away and drilled to further reduce weight without reducing rigidityLight and durable 40/42T sprocketsChrome-plated finish offers hard wearing resistance to corrosionAlloy cassette lockringFor 11-speed HG-X11 MTB chains
Dynamic Chain Engagement (DCE) is used to hold the chain and help prevent chain jump out. This is achieved by using a broader and taller tooth profile in conjunction with a special hooked leading edge and alternate profiled tooth shaping. This provides superior chain retention, lower driving sound, increased durability and drag to a minimum Hollow gear construction for optimized rigidity, lightweight and durability Durable teeth using a plated steel construction supported by a carbon composite (CFRP) carrier body HG 12-speed chain compatible Available in 28T/30T/32T/34T/36T
