*This extended-length MTB (Boost) hub features "Boost-grade adaptability and multi-freezer compatibility." Its 15x100mm front and 12x148mm rear thru-axle designs ensure precise power transmission and torsional resistance in demanding off-road conditions, such as rocky slopes and continuous spurs. *With a total weight of 306±15g and a 28/28 hole straight-pull layout, it features a steel spoke-compatible design. A reinforced bore treatment minimizes spoke tension tolerance to within 4%, ensuring both strength and durability. *Made of a dual-material aluminum alloy 6061 + AL7075, it's compatible with Shimano HG/MS and SRAM XD multi-freezer bodies and disc brake systems, creating a core component for MTB that combines "toughness, compatibility, and efficient transmission" for use with disc brakes.
