SRAM CenterLine X rotor 140 mm, Center Lock

SRAM brake rotor. Needs from your bike: Rotor interface (hubs) and Maximum rotor, front.

The SRAM CenterLine X rotor 140 mm, Center Lock is a brake rotor (component). It requires 2 things of a bike — Rotor interface (hubs) and Maximum rotor, front — read from SRAM. On every bike page its verdict is computed from those requirements against the bike's cited facts: when a fact is missing the answer is "unknown", never a guess.

Requires — Rotor interface (hubs)Center Lock
Requires — Maximum rotor, front≥ 140 mm

Rotor interface (hubs) and Maximum rotor, front are safety-critical: a wrong answer could hurt you, so we say "fits" only when the bike's fact is confirmed by two independent sources. With one source the honest answer is "unknown"; with none it is "unknown — safety-critical".

Does this part fit my bike?
Find your bike under "Fits these bikes" below, or open your bike's "Front brake" region page. The verdict there is computed from this part's requirements against the bike's cited facts — with its confidence and sources.
What does "does not fit" mean here?
That a fact on file for the bike contradicts a requirement of this part — a confident no, with both values shown.
