The State Bicycle Co. Core-Line (2024) is a track / fixed-gear bike — representative silhouette: Track / fixed gear. We have read 1 specification sheet (State Bicycle Co.) and recorded 9 fit facts from it. 3 of the 10 measurements a track / fixed-gear bike needs to answer fit questions are on file; 0 are confirmed by two independent sources. Where a measurement is missing, we say so below — we do not guess.
| Derailleur hanger | No derailleur hanger (track, fixed, single-speed, IGH) |
|---|---|
| Front derailleur mount | No front derailleur mount (1x only) |
| Maximum tyre width (frame) | 28 mm |
| Wheel size (ISO bead seat) | 700c / 29" (ISO 622) |
| Rotor interface (hubs) | No rotor interface (rim brake) |
| Brake actuation | Cable rim brake |
| Freehub body | Threaded freewheel hub (1.37" × 24 tpi) |
| Rear speeds | 1 speeds |
| Shift actuation | Single-speed / fixed (no shifting) |
Confidence: every fact above comes from a single cited source — "derived" on our lattice; none is verified by a second independent publisher yet. A verdict that rests on a safety-critical fact therefore stops at "unknown" rather than "fits".
Not on file (required for a track / fixed-gear bike): Bottom bracket shell · Rear axle spacing · Seatpost diameter · Front axle spacing · Brake mount, front · Brake mount, rear · Pedal thread. The sheet we read does not state them; until a source does, every fit question that needs one of these reads "unknown" — or "unknown — safety-critical" where a guess could hurt you.
- 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 10 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.
