KMC announced the newly debuted X12 in February 2017. msrp_usd is the current KMC USA list price for Silver (EPT 66.00, Aurora 82.50). the global page names SRAM and KMC USA names SRAM Eagle as compatible; some current KMC Europe listings say the X12 fits only Shimano-standard 12 speed (Shimano, Campagnolo, TRP) and not SRAM. All KMC sources exclude SRAM flattop and T-Type. KMC USA lists 234 g for 126 links. Price labels fixed 2026-09-26: moved the KMC USA price of 44 to list_price_usd (a current list price observed 2026-09) and set msrp_usd to null because no launch price is documented.
