In partnership with the United States Consumer Product Safety Commission (CPSC), Shimano has issued a recall of approximately 680,000 road chainsets across the Ultegra and Dura-Ace models. The recall is currently in effect across North America, but a worldwide recall is soon to be announced.
The specific models affected are the 11-speed compatible Ultegra FC-6800, Dura-Ace FC-9000, Ultegra FC-R8000 and Dura-Ace FC-R9100 chainsets, as well as the FC-R9100P power meter variant.
It affects products manufactured prior to 2019, with one of the following two-letter production codes on the rear of the crank arm.
KF, KG, KH, KI, KJ, KK, KL, LA, LB, LC, LD, LE, LF, LG, LH, LI, LJ, LK, LL, MA, MB, MC, MD, ME, MF, MG, MH, MI, MJ, MK, ML, NA, NB, NC, ND, NE, NF, NG, NH, NI, NJ, NK, NL, OA, OB, OC, OD, OE, OF, OG, OH, OI, OJ, OK, OL, PA, PB, PC, PD, PE, PF, PG, PH, PI, PJ, PK, PL, QA, QB, QC, QD, QE, QF, QG, QH, QI, QJ, QK, QL, RA, RB, RC, RD, RE, and RF.
The affected parts, of which there are 680,000 units, were reportedly sold in North America and Canada over the eleven and a half year period between January 2012 through August 2023. Cyclingnews understands this only relates to the products that fall under the CPSC’s jurisdiction, and that the number could be much higher when extrapolated worldwide.
According to the CPSC, the recalled bonded components can separate and break, which can pose a crash hazard to consumers. It reports that Shimano has received 4,519 incidents of cranksets failing through separation of the bonded construction. From these, there have been six reported injuries including bone fractures, joint displacement and lacerations. It is unconfirmed over what time period the incidents were recorded.
Despite their similar appearance, Shimano’s 105 chainsets are not affected by the recall, due to a cold-forged manufacturing process. Likewise, no 10-speed or 12-speed components are affected either.
If you are in North America and believe you have an affected crank, you are advised to immediately stop using it and contact a Shimano dealer or an authorised inspection centre (essentially any store that is familiar with Shimano components and has passed Shimano’s maintenance course). The dealer will then perform an inspection, and where signs of delamination or separation are found, a free replacement will be issued.
Replacements will comprise a hybrid component that mixes a 12-speed chainset fitted with 11-speed-compatible…
