SRAM Paceline X 160mm Center Lock Brake Rotor — Black/Silver, Lightweight Two-Piece Steel Braking Ring with Aluminum Carrier for Quiet Braking

The SRAM Paceline X 160mm Center Lock rotor is a lightweight road disc brake rotor engineered for quiet braking and easy wheel installation, supplied with an internal spline lockring for Center Lock hubs.

The Paceline X blends a steel braking surface with a light aluminum carrier to deliver a smooth, low-noise braking feel while keeping weight down. At 160 mm diameter and 1.8 mm thickness, this rotor is optimized for road bikes that prioritize refined modulation and compatibility with UCI race requirements. Finished in black and silver, it ships with the necessary hardware and a built-in internal spline lockring for quick, secure Center Lock mounting.

How does the Paceline X reduce brake noise?

The Paceline X uses a brake track geometry engineered to dampen vibrations that cause squeal, giving you a quieter experience under a variety of riding conditions. Quieting features are integrated into the steel braking ring while the aluminum carrier controls heat and structural stability.

• Paceline brake track profile designed to reduce vibration and squeal
• Steel braking surface for consistent pad contact and sound management
• Aluminum carrier that stabilizes the rotor and disperses heat

Will this rotor fit my Center Lock wheel and what hardware is included?

The rotor is built for Center Lock hubs and arrives with an internal spline lockring, so it installs directly to compatible hub splines without extra adapters. SRAM includes the necessary fasteners, simplifying installation and ensuring secure mounting.

• Internal spline lockring included for direct Center Lock mounting
• All required installation hardware supplied in the package
• Compatible with standard Center Lock hub interfaces on road wheels

What are the dimensions, materials, and weight of this rotor?

The Paceline X uses a two-piece construction: a steel braking ring and a lightweight aluminum carrier. It measures 160 mm across, is 1.8 mm thick, and weighs approximately 132 grams, striking a balance between durability and low mass.

• Diameter: 160 mm — suitable for most road braking setups
• Thickness: 1.8 mm for structural reliability and pad contact
• Weight: ~132 grams, achieved by combining steel and aluminum components

How do the rotor's design details make wheel removal and racing compliance easier?

Rounded, chamfered edges simplify sliding a wheel into place during installation and removal, and the rotor profile is compatible with UCI race equipment standards. Those design choices reduce the chance of snagging when changing wheels under time pressure.

• Rounded edges for smoother wheel installation and removal
• Road-focused sizing and profile aligned with UCI equipment expectations
• Low-profile finish reduces interference during wheel swaps

Who is this for: The SRAM Paceline X 160mm rotor is aimed at road cyclists who want quieter braking and lower weight without sacrificing durability — ideal for racers, club riders, and cyclists who change wheels often and need a reliable Center Lock solution. If you run Center Lock hubs and prioritize refined feel, straightforward installation, and a road-specific rotor profile, the Paceline X is a suitable upgrade.
