FSA MegaExo Omega crank to BSA frame, Di2 compatible (BB-4000)

FSA bottom bracket for BSA 68 mm; fits the FSA MegaExo 19 mm spindle. fullspeedahead.com refuses scripted requests (HTTP 403), so the facts come from web.archive.org captures of FSA's shop; the shop lists 50 g for nearly every bottom bracket whatever its type, so that figure is not recorded and only other weights are kept. Years unknown (first year null; last_seen gives the latest capture). Fixed 2026-09-27: list_price_usd is now $48, the regular price on FSA USA's own store (fsaproshop.com, part number 200-1893, read September 2026), replacing $48 from FSA's international shop (May 2026 capture), which sends US buyers to the US store, so that figure is kept in notes only under the US price venue rule.
