Sram Centerline X Road CLX-R (Centerlock)

Pro-Tier Cooling. Lightweight Precision.

The Sram Centerline X Road takes the proven Centerline track and mounts it to a lightweight, aerodynamic aluminum spider. This two-piece construction allows the steel braking surface to expand and contract under heat without warping the core, ensuring your brakes stay consistent and "rub-free" even on the longest, most technical alpine descents.

Why the CLX-R is the Gold Standard for Road Disc:

• Two-Piece Design: The high-strength aluminum center carrier acts as a massive heat sink, pulling thermal energy away from the braking track. This prevents brake fade and ensures a predictable "bite" point during high-speed mountain riding.

• Whisper-Quiet Braking: Featuring the "Centerline" track design, the vent holes are strategically placed to minimize vibration and harmonic noise. Say goodbye to the "turkey warble" often associated with inferior disc rotors.

• Rounded Safety Edges: Specifically engineered for the road peloton, the CLX-R features UCI-compliant rounded edges, reducing the risk of injury in the event of a group pile-up.

• Aerodynamic Spider: The sleek, black aluminum carrier isn't just for weight savings; its shape is optimized to minimize air turbulence, making it the perfect match for deep-section aero wheels like the Reserve 42|49.

• Centerlock Compatibility: Designed for the modern standard, providing a faster, more secure installation and superior alignment compared to traditional 6-bolt systems.

• Optimized for Road & Gravel: While it’s light enough for the World Tour, the CLX-R is rugged enough for the "unbound" grit of competitive gravel racing, offering consistent performance in dust, mud, and rain.

The Alegro Perspective: In the shop, we call the CLX-R the "Silent Partner." When you’re riding a high-end carbon bike like the Scott Addict RC, the last thing you want to hear is your brakes rubbing or squealing. The aluminum spider on these rotors makes them incredibly stiff, which is why they stay so true. If you’re building a dream road or gravel rig with Sram Red or Force AXS, these are the only rotors that truly complete the look and performance of the bike.
