FSA MegaExo SL-K crank to BSA frame, Di2 compatible (BB-8681)

FSA bottom bracket for BSA 68 mm; fits the FSA MegaExo 24 mm spindle (24 mm class, like Shimano HollowTech II). 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, list_price_as_of and price_basis set to null because the only price, $47 in the June 2025 capture, came from FSA's international shop, which sends US buyers to FSA USA's store (fsaproshop.com), and that store did not list part number 200-0007000200 on 2026-09-27; the international price is kept here only, per the US price venue rule.
