Shimano Bicycle Components have issed a voluntary recall on some Hollowtech II crankset manufactured prior to July 2019. In order to allow for an effecient and effective recall and inspection process, Shimano has called upon Local Bike Shops to inspect and process any cranks Please read on for all the details and how to verify if your crankset is affected by the recall.
Here is how to know if your crankset is affected:
• Step 1A – Identify the model number of your crankset
• The affected model numbers 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 crank is not affected, and no further action is needed.
• YES: Proceed to STEP 1B.
Step 1B – Identify the production code stamped on your crank arm (blue box on the image)
• A production code is stamped on the inside of the crank arm near the bottom of the arm.
The affected models are pre-July 2019 production and have the following two-letter
production code on backside of the crank arm where the pedals are attached: KF, KG,
KH, KI, KJ, KK, KL, LA, LB, LC, LD, LE, LF, LG, LH, LI, LJ, LK, LL, MA, MB, MC, MD,

Please proceed to Step 2 if your crank has this code. If your crankset does
not have one of these codes, please proceed to Step 3.
• If you have noticed any changes in the feeling of the crank when you pedal or hear noise
or creaking, please proceed to Step 2.
• Consumers who believe they have an applicable product or are unsure how to check the
manufacturing code are asked to contact an authorized Shimano retailer to schedule a
free crankset inspection. Please see below for instructions on how to figure that out. You
may also call us at 514-683-2240 for assistance.
• Consumers with cranksets that do not fall within the specified date codes do not need to
take further action regarding this safety recall or inspection. Please proceed to Step 3.
Step 2 – Take the Bicycle to the Retailer for Inspection
o You can bring your bike to our service team starting October 1st, please book your appointment in advance so that we can process and submit any affected cranksets in an effecient manner.
• We will inspect the crankset for signs of bonding separation or delamination.
• We will submit the required information to Shimano so that we can document the
inspection, results, and replacement cranks if needed.
• Shimano is required to maintain this information for CPSC reporting and to ensure the
process is completed.

the inspection will be provided a free replacement crankset* from Shimano that we will professionally install.

your patience and diligence in having the safety inspection done. You may continue
using your crankset as normal.
• If your crank requires replacement, we appreciate your patience to complete this

• Have your bike tuned up and inspected regularly (ask your retailer for recommendations
based on your riding habits).

indicate wear out, breakage, or need for adjustment to some part of your bike.
