Shimano 11-Speed Hollowtech II Crankset Recall Notice- CLICK HERE
Shimano is issuing a voluntary recall of select bonded11-speed HOLLOWTECH II road cranksets sold from January 2012 through August 2023 for a possible bonding separation issue. Keep reading for a full breakdown of how to do a basic check to see if your Shimano road cranks are affected and what to do next if you are affected.
The recall affects the following Shimano Hollowtech II road crank models ONLY:
- DURA-ACE FC-9000
- DURA-ACE FC-R9100
- DURA-ACE FC-R9100P
- ULTEGRA FC-R8000
- ULTEGRA FC-6800
This recall affects both cranksets spec'd on complete bikes and purchased aftermarket. You can check for your exact Shimano model number by looking at the inside of the drive side crankarm (right hand side) near the bottom just above the pedal threads (the YELLOW box in the image below).
If you have Shimano Ultegra or Dure-Ace crankset model that is covered this recall you now need to confirm if the crankset is directly affected by this recall and that is done by checking the production code against the list of affected codes that Shimano has provided - that list is below. To find the two letter production code, look on the same drive side crank arm for that code that is stamped just below the crank model information (the BLUE box in the image above). If you have a Dura-Ace crankset you will also need to check the production code on the non-drive (LH) crankarm.
Affected crank production codes on Ultegra and Dura-Ace cranksets are: 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.
If you have a crankset with a production code that is on this list please contact us or Mighty Riders and we will set an appointment to bring your bike in. We will then conduct a full inspection of the crankset and determine the next steps. Those next steps could be either us sending the cranks back to Shimano for further inspection and replacement or that the cranks are ok to ride but will need to be monitored going forward both by the rider and us. If your crankset is ok you will still need to be paying attention for any changes in performance with your crankset - reporting any creaking or other issues to us or Mighty.
If your crankset has a non-affected production code then an immediate inspection by a Shimano dealer like us or Mighty Riders is not needed but we will continue to check your crankset on future service visits. Going forward you will also be paying attention for any changes in performance with your crankset - reporting any creaking or other issues to us or Mighty - even if your Shimano crankset is not affected by this recall. The scope of this Shimano recall may change, we will be on top of communicating the latest information to our valued customers through all our channels (website, social media, and newsletter).
We are here to support our customers and riders and are always available (phone, email, text, in store) to discuss any of this with you.
