00:00 Shimano recently recalled over 2.8 million chainsets. In North America, there
00:05 is a stop right notice in place. In other parts of the world, it's just a recall
00:10 for inspection. The advice I'm going to give you today is by no means an
00:14 alternative course of action to the recall itself. If you have an affected
00:19 crank, you should absolutely get this seen to by your local Shimano dealer,
00:23 who will conduct a far more thorough investigation. However, since the advice
00:28 in the rest of the world is that you can keep riding these cranks if deemed to be
00:32 safe by your local Shimano dealer, I believe that we should all be armed with
00:36 a little bit more knowledge on what to look out for. Because the cranks that did
00:40 fail, didn't fail on the first ride. So, playing closer attention to them for the
00:45 rest of your ownership will be very smart to do. Do bear in mind that some
00:50 defects may develop which my method of checking may not spot. Of course, if
00:54 you're unsure, then get them seen to by your local Shimano dealer. The first
01:01 thing to do is check the code on your crank to see if it matches up to those
01:05 that have been recalled. Remember, it's only the Ultegra 6800 and 8000 and
01:11 Dura-Ace 9000 and 9100 series that have been recalled so far. And on screen, you
01:17 can see all of the affected codes. You can find the code right here on the
01:22 inside of both crank arms. It's worth checking both arms just in case they
01:27 have different codes on them. Like I said at the start, if your chainset is subject
01:31 to the recall, for those in North America, do not ride your cranks as the recall
01:36 does go along with a stop ride notice. If you're in the rest of the world, then
01:41 ride with caution. This is the information provided by Shimano, so
01:45 whether you think it makes any sense is up to you, but that is what it is. Next,
01:51 clean your cranks. Carefully remove the chain, spritz over with your cleaning
01:56 fluid of choice so that you can get a really good look at your cranks, and this
02:00 will also help you feel for any imperfections. Once clean, first check the
02:05 right hand crank arm around the bolt circle, specifically these joints here.
02:10 You want to be looking for any issues such as any cracking or steps, or better
02:15 put, any sign that may indicate that the crank arms and chain rings are coming
02:19 apart. From there, look further down the right hand crank arm, especially along
02:25 this ridge on the inside of the arm. Feel the arms to see if you can spot any
02:29 signs of cracking or splitting. Be careful, as if there is a crack or any
02:34 splitting, the metal could be sharp, so be wary of not causing yourself any harm.
02:39 Next, move over to the left hand crank arm. Again, look along the inside edge for
02:45 the exact same signs of damage. A key area to inspect on the non-drive side is
02:50 at the top of the arms, where the crank bolts onto the spindle. Inspect the areas
02:55 around the bolt holes on both sides, and also on this inside edge. After that, look
03:02 over the entirety of the chain set for any other signs of damage, corrosion,
03:06 splitting, steps, or cracking. Bike shops who are conducting inspections will have
03:13 a more rigorous inspection process, as they're going to be removing the entire
03:17 chain set, and then removing the chain rings themselves, to get a good look at
03:21 every angle of the cranks. As I said at the start, if you have an affected chain
03:26 set, then take it to your local Shimano dealer. But, if you are to continue to
03:31 ride your cranks, then just keep a really good eye on them.
