Service Description

This specifically concerns the Shimano ULTEGRA FC-6800, DURA-ACE FC-9000, ULTEGRA FC-R8000, DURA-ACE FC-R9100 and FC-R9100-P 11-Speed Bonded HOLLOWTECH II Road Cranksets in Europe. The model numbers are stamped on the inside of the crank arm near the bottom of the arm (see yellow square in the image below). Reports received by Shimano indicate that the bonded parts of the crank arm could separate and break, posing potential fall and injury hazards to consumers. To remedy this situation, Shimano will have any applicable crankset inspected. Shimano will replace any crank arm that fails the inspection process. This inspection is designed to determine whether the crank arms show a possible bonding separation issue and to swiftly remove any possible safety hazard to our consumers. Not all ULTEGRA and DURA-ACE cranksets need to be inspected. Only cranksets produced between June 1, 2012, up to and including June 30, 2019, need to be inspected. A manufacturing code is stamped on the inside of the crank arm near the bottom of the arm (see the blue square in the image above). The affected models are pre-July 2019 production and have the following two-letter production codes: 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.
