RX Road 2x12 Speed Hydraulic Disc Brake Groupset Notice The original LTWOO RX Disc packaging is oversized and significantly increases shipping costs (approximately USD 40–50). To help you save on shipping, we offer a "Without Original Box" option. The price difference reflects the reduced shipping cost only—both options include the same product, accessories, and warranty service. Please purchase with confidence. Version Guide The shifters and rear derailleurs come in two versions: Carbon Fiber: Lighter and offers finer shifting. Best for experienced riders seeking maximum speed and weight savings.
