SRAM CenterLine X Disc Brake Rotor 140mm, CenterLock, Black, Rounded, Lockring Included
SKU code: PSI-SR005018037034
CenterLine X is the lighter, two-piece version of SRAM's Centerline rotor: an alloy centre carries a steel brake track, so you keep the smooth, quiet Centerline braking with less weight on the wheel. This is the 140mm CenterLock version in black, supplied with a SRAM lockring.
Highlights
- Two-piece design: alloy centre with a steel brake track
- 140mm diameter, CenterLock mount
- 1.85mm thick; replace once worn below 1.55mm
- Rounded outer edge makes wheel installs easier and is UCI-compliant
- SRAM CenterLock lockring included (internal-tool type)
Lighter where it counts
The two-piece build takes weight out of the spinning part of the wheel, while the steel track handles the braking. SRAM rates CenterLine X for both road and mountain bike brakes.
Choosing 140mm
SRAM's sizing guide puts 140–160mm rotors on most road, cyclocross and gravel bikes, and most drop-bar frames only take 140 or 160mm.
Compatibility and fit
Needs a CenterLock (splined) hub. Check that your frame and fork accept a 140mm rotor and that you have the correct caliper adaptor. The included lockring is an internal-tool type; some thru-axle hubs need an external-tool lockring instead, so check your hub before fitting. Bed in new rotors and pads before riding hard, and fit a new rotor whenever you change pad compound.
