Shimano (Singapore) Pte. Ltd. (“Shimano”), starts an inspection and replacement program of selected bonded 11-speed HOLLOWTECH II road cranksets produced between June 1, 2012, up to and including June 30, 2019, for a possible bonding separation issue.

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. 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. The way to identify if a crankset should be inspected is provided in the WHAT TO DO section below.

Shimano will replace any cranksets that fail the inspection process free of charge.

Reports received by Shimano indicate that the outer cover of the crank arm may start to separate from the main crank arm body, posing potential fall and injury hazards to consumers.

To know if this process applies to your crankset, please follow the instructions in STEP 1.

The affected products are DURA-ACE and ULTEGRA branded cranksets with the following model numbers: ULTEGRA FC-6800, FC-R8000 and DURA-ACE FC-9000, FC-R9100 and FC-R9100-P. 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).

Does the model number on your crank arm match the model numbers above?

NO: The crankset is not affected, and no further action is needed.

YES: Proceed to STEP 1B.

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.

Does the manufacturing code on your crank arm match any of the two-letter productions codes above?

NO: The crankset is not affected.  No further action is required.

YES: Proceed to STEP 2.

Consumers who believe they have an affected product are asked to contact an authorized Shimano dealer to schedule a free crankset inspection. If you are unsure of how to check the manufacturing code visit your local Shimano dealer. Please see the CONTACT section below for instructions on how to contact Shimano for assistance.

Consumers with cranksets that do not fall within the specified model number and manufacturing codes do not need to take further action. Please proceed to STEP 3.
