描述
ROTOR Gravel Axle Offset – 24MM
ROTOR 礫石車偏置軸心(24mm)
Product Overview
The ROTOR Gravel Offset Axle is a 24mm steel spindle designed for ALDHU and VEGAST modular cranksets. It creates a wider chainline (46mm) and Q-Factor (152.5mm) specifically for gravel bikes, cyclocross, and road frames that require a wider drivetrain clearance, such as those using Shimano GRX or SRAM Wide components.
