4iiii Announce Fast Replacement

News for riders affected by the ongoing Shimano crank recall who also have a 4iiii power-meter.

You will probably have heard about Shimano’s safety recall regarding their 11-speed HOLLOWTECH II road cranksets. Some cranks produced between June 1, 2012 and June 30, 2019 have faults in their manufacturing. This can cause the bonded parts to separate and crack. Shimano are asking for riders to check their cranks and if their serial markings match, to send them for inspection and replacement. This announcement from 4iiii is for those whose faulty cranks were fitted with one of their power-meters.

4iiii and Shimano have agreed that if your crank needs replacing, Shimano will provide a rebate for the value of the power-meter. Once you have your new crank back from Shimano, you can use the rebate to order a new power-meter. While no-one wants to be without their bike, in this case it’s for the best. Some of the cranks have failed catastrophically while being ridden. Better a period of no bike than a visit to A&E.

If you are worried about being without your power-meter for too long 4iiii have some good news. If you’re in the UK, they will fit your new power-meter in 3-5 days, getting you back up to speed with minimal delay. Of course if you’re after a new power-meter, then you can also receive the same fast turnaround. We’re currently reviewing the latest 4iiii PRECISION 3+ unit, that incorporates Apple’s Find My feature. This allows you to find your bike should it go missing.

What to look for

If you’re worried about your cranks then you can check out the Shimano page in the link above. Here’s the short version. The recall is for 11-speed cranksets only, specifically: ULTEGRA FC-6800, DURA-ACE FC-9000, ULTEGRA FC-R8000, DURA-ACE FC-R9100 and FC-R9100-P 11-Speed Bonded HOLLOWTECH II. To check if your crank is one of these, take a look at the rear of the crank, by the pedal axle. You’ll see a block of numbers and letters. If the the top number (outlined in yellow) matches the numbers above, then you need to do another check. Look for a pair of capitalised letters (outlined in blue). If they match any of the letters in the following list, then you need to get the cranks checked.
