00:00 Shimano recently recalled over 2.8 million chainsets. In North America, there is a stop
00:06 ride notice in place. In other parts of the world, it's just a recall for inspection.
00:11 The advice I'm going to give you today is by no means an alternative course of action
00:15 to the recall itself. If you have an affected crank, you should absolutely get this seen to
00:21 by your local Shimano dealer, who will conduct a far more thorough investigation.
00:27 However, since the advice in the rest of the world is that you can keep riding these cranks
00:31 if deemed to be safe by your local Shimano dealer, I believe that we should all be armed
00:36 with a little bit more knowledge on what to look out for. Because the cranks that did fail,
00:41 didn't fail on the first ride. So, playing closer attention to them for the rest of your ownership
00:46 will be very smart to do. Do bear in mind that some defects may develop which my method of
00:52 checking may not spot. Of course, if you're unsure, then get them seen to by your local Shimano dealer.
00:59 The first 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 Dura-Ace 9000 and 9100
01:14 series that have been recalled so far. And on screen, you can see all of the affected codes.
01:20 You can find the code right here on the inside of both crank arms. It's worth checking both arms
01:25 just in case they have different codes on them. Like I said at the start, if your chainset is
01:31 subject to the recall, for those in North America, do not ride your cranks as the recall does go
01:36 along with a stop ride notice. If you're in the rest of the world, then ride with caution. This
01:43 is the information provided by Shimano. So, whether you think it makes any sense is up to you, but
01:49 that is what it is. Next, clean your cranks. Carefully remove the chain, spritz over with
01:55 your cleaning fluid of choice so that you can get a really good look at your cranks. And this will
02:00 also help you feel for any imperfections. Once clean, first check the right-hand crank arm around
02:06 the bolt circle, specifically these joints here. You want to be looking for any issues such as any
02:12 cracking or steps, or better put, any sign that may indicate that the crank arms and chain rings
02:19 are coming apart. From there, look further down the right-hand crank arm, especially along this
02:25 ridge on the inside of the arm. Feel the arms to see if you can spot any signs of cracking or
02:30 splitting. Be careful, as if there is a crack or any splitting, the metal could be sharp. So,
02:36 be wary of not causing yourself any harm. Next, move over to the left-hand crank arm. Again,
02:43 look along the inside edge for the exact same signs of damage. A key area to inspect on the
02:49 non-drive side is at the top of the arms, where the crank bolts onto the spindle. Inspect the
02:55 areas around the bolt holes on both sides, and also on this inside edge. After that, look over
03:02 the entirety of the chain set for any other signs of damage, corrosion, splitting, steps, or cracking.
03:09 Bike shops who are conducting inspections will have a more rigorous inspection process,
03:14 as they're going to be removing the entire chain set, and then removing the chain rings themselves,
03:19 to get a good look at every angle of the cranks. As I said at the start, if you have an affected
03:25 chain set, then take it to your local Shimano dealer. But, if you are to continue to ride
03:31 your cranks, then just keep a really good eye on them.
