The Shimano Rotor 140mm Lock Ext. is a compact, high-performance disc brake rotor designed for riders who demand precise, consistent braking in a lightweight package. With its 140 mm diameter, it is ideal for road, gravel, and cyclocross setups where modulation, control, and weight savings are key. The lock-style interface (commonly Center Lock) makes installation and removal quick and secure, allowing you to swap rotors or wheels with minimal fuss. Shimano’s proven rotor design helps manage heat buildup, reduce brake fade on long descents, and deliver reliable stopping power in both dry and wet conditions.
This rotor is a great choice for riders upgrading from older or worn-out discs, or for those fine-tuning their braking performance on performance-oriented bikes. Its smaller size can help reduce overall system weight and improve responsiveness, while still offering ample braking force when paired with quality calipers and pads. Whether you are racing, training, or simply enjoying fast weekend rides, the Shimano Rotor 140mm Lock Ext. offers a dependable, low-maintenance solution that integrates seamlessly with modern Shimano disc brake systems.
