The Specialized Rockhopper Sport CUES is a XC mountain bike — representative silhouette: XC hardtail. We have read 8 specification sheets (Specialized Bicycle Components, KMC, Shimano, Elvedes and Tektro) and recorded 25 fit facts from them. 9 of the 16 measurements a XC mountain bike needs to answer fit questions are on file; 3 are confirmed by two independent sources. Where a measurement is missing, we say so below — we do not guess.

Confidence: 5 facts are verified by two independent sources; the rest come from a single cited source ("derived").
Not on file (required for a XC mountain bike): Bottom bracket shell · Derailleur hanger · Maximum tyre width (frame) · Brake mount, front · Brake mount, rear · Freehub body · Pedal thread. The sheets we read do not state them; until a source does, confirm these measurements before choosing a part that depends on them.
- Why do so many verdicts on this bike read "unknown"?
- Because a verdict needs the bike's measurement for every dimension a part requires, and 7 of the 16 required measurements are not on file. "Unknown" means we could not check — not that it fits, and not that it does not.
- Will the verdicts change?
- Yes. When a second independent source confirms a measurement — or a first one states a missing one — the verdicts are recomputed from the new facts. Nothing on this page is typed by hand.
