Sram Centerline Rounded 2-Piece (ISO)

Thermal Stability. Quiet Precision.

The Sram Centerline 2-Piece Rotor is designed to minimize vibration and maximize cooling. The aluminum center piece acts as a massive heat sink, pulling warmth away from the braking surface to prevent brake fade and fluid boiling. Featuring the "Centerline" track geometry, it provides a consistent friction coefficient throughout the entire rotation, eliminating the "pulsing" feel often found in lightweight rotors.

Why the 2-Piece Centerline is a Professional Grade Upgrade:

• Advanced Heat Management: The 2-piece construction allows the steel outer ring to expand and contract independently of the aluminum spider, virtually eliminating rotor warping and "turkey warble" noise during high-heat braking.

• Rounded Safety Edges: Features UCI-compliant rounded edges, making them safer for group rides and professional racing, while also making wheel swaps faster by guiding the rotor into the caliper more easily.

• Consistent Braking Surface: The "Centerline" cutout pattern ensures a constant contact patch between the pad and the rotor, resulting in a smooth, linear braking feel with zero "grabby" spots.

• Lightweight Aluminum Spider: By replacing the center of the rotor with high-grade aluminum, Sram shaves critical unsprung weight from your hubs, improving suspension response and acceleration.

• Whisper-Quiet Operation: Designed specifically to reduce harmonic vibration. When paired with Sram HRD or Level brakes, it provides a silent, premium braking experience in both wet and dry conditions.

• Standard 6-Bolt Interface: Features the universal 6-bolt mounting system, making it a high-performance "plug-and-play" upgrade for almost any mountain, gravel, or road disc hub.

Technical Specifications:

• Material: Steel Braking Track / Aluminum Inner Spider

• Mount Type: ISO 6-Bolt

• Edges: UCI-Compliant Rounded

• Compatibility: Works with all Sram and Avid brake systems (and most 3rd party calipers)

• Weight: Performance-focused (approx. 125g for 160mm)

The Alegro Perspective: In the shop, we recommend the Centerline 2-Piece for any rider who finds themselves "cooking" their brakes on long descents. Standard 1-piece rotors tend to "dish" or warp when they get too hot, leading to annoying rubbing for the rest of the ride. The 2-Piece design stays straight and quiet no matter how hard you lean on the levers. It’s the "pro" choice for a reason. It looks stunning on a high-end build and performs even better.
