SRAM Centerline X Disc Rotor

Upgrade your bike’s stopping performance with the SRAM CenterLine X 2‑Piece Rotor — a premium, lighter-weight upgrade from the standard CenterLine design. Designed to deliver smooth, quiet, and consistent braking across road, gravel, and trail applications, CenterLine X rotors blend rider-friendly performance with durable construction.

Why They’re Great

• Two-Piece Lightweight Design: The CenterLine X uses an aluminum alloy center carrier bonded to a stainless steel braking surface to cut rotating weight while retaining strength and durability — giving you quicker wheel spin and less unsprung mass.
• Consistent & Quiet Braking: SRAM’s CenterLine braking track design promotes smooth friction engagement throughout each revolution, which helps reduce vibration and unwanted noise at the caliper.
• Improved Heat Management: The combination of aluminum carrier and steel track helps dissipate heat more efficiently than one-piece rotors, helping maintain performance on long descents and repeated braking.
• Rounded, Safe Edges: UCI-compliant rounded edges make wheel installation easier and safer, while the machined profile helps evacuate dirt, water, and grit for more dependable performance.
• Multiple Sizes & Mounting Options: Available in 140 mm, 160 mm, and 180 mm diameters with both 6-Bolt and CenterLock hub standards — so you can dial in brake power and fitment for your bike type and riding style.

What This Rotor Is Meant For

The SRAM CenterLine X rotor is built for riders who want:

• Enhanced braking performance without a major weight penalty
• Quiet, confidence-inspiring stops on the road, gravel, or XC trails
• Versatility across different bikes (road, gravel, mountain)
• Improved thermal performance on longer rides or technical descents

Its two-piece construction is a clear step up from basic one-piece rotors, making CenterLine X a great choice for cyclists looking for that sweet spot between price, weight, and performance.

Who Should Buy It

• Road & Gravel Riders — Who want a lighter, smoother-feeling brake setup for speed and endurance.
• Cross-Country & Trail Cyclists — Who need reliable modulation and thermal stability on mixed terrain.
• Commuters & All-Around Cyclists — Who want dependable stopping power in all conditions.
• Upgraders & Enthusiasts — Who are ready to move past entry-level discs without breaking the bank.

Rotor Size Guide & Fit

• 6-Bolt: Traditional bolt-on interface — simple and widely supported.
• CenterLock: Easy spline fit for compatible hubs (lockrings may be sold separately on some versions).

Why Riders Choose CenterLine X Over Standard Rotors

• Better Modulation: Smoother brake feel with less vibration and noise than basic one-piece rotor designs.
• Weight Savings: Two-piece rotor construction trims grams where it matters — especially noticeable on road and gravel builds.
• Durability Meets Performance: Excellent blend of strength and heat management for everyday performance.

Pro Tips

• Match rotor size to your ride: Bigger rotors = more leverage and cooling but slightly more weight.
• Check hub type before ordering: CenterLock rotors often need the correct lockring if not included.
• Break them in properly: New rotors and pads benefit from a few controlled stops to bed surfaces and reduce squeal.
