Reference prices, not live offers. “Verify” marks standards we can't check yet.
01 — Fit engine
Checked where we can. Flagged where we can't.
Wheel size, travel, freehub, brake mounts, clamp diameters: every pair of parts is compared against its standard as you build. Where the catalog lacks the data, the part is marked “Verify” instead of passing silently.
