FSA Bearing Kit BB90 Trek for FSA alloy MegaExo cranks

FSA bottom bracket for Trek BB90; 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 is now $50, the regular price on FSA USA's own store (fsaproshop.com, part number 230-6001, read September 2026, listed as sold out under the name Bearing Kit Trek Madone), replacing $41 from FSA's international shop (May 2021 capture), which sends US buyers to the US store, so that figure is kept in notes only under the US price venue rule.
