The Shimano Tiagra SM-RT54 Center Lock Brake Rotor 160mm is a dependable disc brake rotor designed for road, mountain bike, urban and trekking use. Featuring Shimano’s proven Center Lock mounting system, it offers straightforward installation, secure fitment and consistent braking performance for compatible disc brake setups.
Its precision-cut stainless steel braking surface is designed to improve pad clearing and support heat management under load, while the alloy spider increases rotor rigidity and helps keep weight down. Supplied complete with an internal lock ring, the SM-RT54 is ready for installation on compatible Center Lock hubs.
Shimano Center Lock Mounting
The Center Lock interface provides a secure and convenient way to fit the rotor to a compatible hub. Compared with multi-bolt rotor systems, Center Lock simplifies installation and removal while maintaining accurate rotor positioning.
160mm Rotor Size
With a 160mm diameter, the SM-RT54 offers a versatile balance of braking power, modulation and weight. This size is commonly used across road bikes, gravel and all-road bikes, mountain bikes, hybrid bikes and urban and trekking bikes.
Always check your frame, fork, caliper adaptor and hub compatibility before fitting.
Precision-Cut Stainless Steel Braking Surface
The rotor’s stainless steel braking track is precision cut to help clear contaminants from the pad contact area. This is particularly useful in wet or dirty riding conditions, where effective pad clearing can help support consistent braking performance.
Improved Cooling Under Load
The rotor surface is designed to promote airflow and heat dissipation during braking. This helps manage temperature under higher braking loads and can contribute to more consistent brake feel.
Alloy Spider Construction
An alloy spider supports the braking surface, improving overall rotor stiffness while reducing unnecessary weight. This combination helps maintain stable braking performance without making the rotor excessively heavy.
Designed to Support Pad Performance and Life
The contact surface and cut-out pattern are designed to improve pad clearing and cooling. This can help support consistent pad contact and contribute to improved pad lifespan when used with the correct braking components.
Resin Pad Compatible
The Shimano SM-RT54 rotor is designed for use with resin brake pads only. It should not be used with metallic or sintered brake pads unless Shimano specifically states otherwise for your braking system.
Internal Lock Ring Included
The rotor is supplied complete with an internal Center Lock lock ring, helping simplify installation on compatible hubs.
