Shimano 11 Speed Hollowtech II Inspection Notice
We have signed up to help Shimano riders with the crank inspection and replacement program.
First things first, currently the expected date for us to be able to start the claim process is October 16th 2023. Then from October 23rd replacement cranksets will start being sent from Shimano for cranks that failed the inspection.
Secondly, this will not be a fast process as this is a major recall and there are thousands and thousands of the potentially affected range of cranks out in the wild. Also just because your crank may fall under the range of cranks affected by this recall, does NOT mean yours will in fact fail. The cranksets below have some production runs that fall into this range.
If you have concerns please follow the steps below, and feel free to contact us if you have any questions.
What to Do
STEP 1 – Determine whether your crankset needs to be inspected
Step 1A - Identify the model number of your crankset
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).
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.
STEP 1B – Identify the manufacturing code stamped on your crank arm
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).
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 authorised Shimano dealer to schedule a free crankset inspection. If you are unsure of how to check the manufacturing code visit your local Shimano dealer.
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.
STEP 2 – Take the bicycle to the dealer for inspection
Shimano has developed the crankset inspection process and will soon provide clear instructions and tutorials for dealers. Shimano anticipates that the inspections will be possible starting from OCTOBER 16th, 2023.
The dealer will inspect the crankset for signs of bonding separation or delamination.
Consumers whose cranksets show signs of bonding separation or delamination during the inspection will be provided a free replacement crankset from Shimano that the dealer will professionally install. If your crankset needs replacement following the inspection, please do not use it. If a replacement crankset is temporarily unavailable, Shimano will notify you through your dealer when the replacement is ready.
The replaced crankset will be a new version, which may feature a different cosmetic appearance while maintaining the same level of performance.
STEP 3 – Ride safely and continue to maintain your bicycle/equipment.
If your crankset passes the inspection and has no signs of delamination, we appreciate your patience and diligence in having the inspection completed. Please continue to enjoy your ride.
Have your bike tuned up and inspected regularly, ask your dealer for recommendations based on your riding habits. Pay attention to changes in the sound and feel of how your bike is riding. Shimano urges all users to thoroughly read the user manual provided with the product (and available online at: si.shimano.com to ensure safe usage and proper maintenance.
Shimano encourages all riders to maintain their bicycle and riding equipment diligently.
