My first suspicion is the chain hitting the front derailleur cage. The clicking is fairly loud and occurs continuously whenever you pedal. If the bottom bracket bearings were damaged you would feel it through the cranks rather than hearing it and there would be clicks once per crank rotation. It's also possible that you have chainsuck going on. A worn ...

It's just the regular old 20-spline cartridge type tool, i.e. Park BBT-22. I have seen a few like this, although I don't really know what the deal is with them. While there are now an enormous number of outboard type BB tool spline patterns, internal cartridge BBs pretty much exclusively use either the Shimano-originated 20-spline tools or the smaller Campy ...

It is correct that you've got an 'English' or 'ISO' threaded cartridge bottom bracket; this refers to the interface between the BB and the frame. But you also need to consider the interface between the BB and the cranks. This has what is called a "square taper" spindle, and because the bike world is filled with competing standards, there is more ...

I replaced the BB on this crankset recently. I have a spreadsheet here with all Shimano 9/10/11 speed cranksets & BBs https://docs.google.com/spreadsheets/d/1HdcNgmQKFA-lAqQJ3lXQ8SwA4tblAKiOXe9XYJJHYN8/edit The M523 is the only crankset with these chainrings and bottom bracket. However, the M522 is almost identical with 42/32/24 chainrings & no need ...

If you're just riding casually, then a simple chainring replacement is probably all you need. You don't have to match the styling, just the Bolthole Circle Diameter (BCD) and number of boltholes. It looks like a 4 bolt pattern, but there are a number of standard sizes (naturally) Personally I use a 100% printout of the PDF at https://cdn.shopify.com/s/...

I would recommend you to replace not only the chainrings and crankset, but also the bottom bracket. Octalink is getting rare because it is a big honking design flaw. There are not one but two flaws in it. The first flaw is that it lacks press fit, so the left crank is free to rotate in its splines minutely forwards and backwards. If you rest your weight by ...

Can a set of Stronglight JIS track crank arms (107mm axle length) be fitted to my BB (110mm spindle length), or must the axle length of a crank arm match the spindle length of the bottom bracket? Possibly. If both the bottom bracket and the cranks are JIS, the difference is only 3 millimeters. It will move the cranks 1.5 millimeters outwards. Thus, because ...

Axle length and spindle length are the same thing. Three-piece cranks typically specify a required axle/spindle length to achieve a specific chain line, I.e. how far away the chain rings are from the center plane of the frame. An axle/spindle longer or shorter by x millimeters will move the cranks x/2 millimeters outboard or inboard respectively. Some ...

Your bottom bracket is screwed into the eccentric. You'll be replacing the bottom bracket. The fact that it's in an eccentric doesn't affect the part choice. The eccentric is more like part of the frame. To install FC-S501 you need any Shimano road Hollowtech 2 BB, as indicated by BB-SM4600 being the model called out in the Shimano exploded view diagram for ...

You have a square taper bottom bracket. Actually an eccentric one, they are used to tension your chain. You should be able to use any square taper crankset. However, various cranksets require square tapers of different width. We cannot see the width of your BB, but one typically also changes the bottom bracket when changing the crankset and one just buys ...

Per https://www.ribblecycles.co.uk/ribble-endurance-sl-r-series-frameset/ Bottom Bracket: Press Fit BB86. A Shimano BBR60 is threaded: SM-BBR60 SHIMANO ULTEGRA - Bottom Bracket - Threaded - HOLLOWTECH II - 68/70 mm shell width So no, the BBR60 won't fit. Something like a Wheels Manufacturing BB86/92 would fit, though. And it won't start making noises ...

This question about loose crank arms has been asked and answered several times before on this site, but yours is the worst I've ever seen I think. Unfortunately your crank arm is ruined. If the alloy crank gets loose and is ridden on the hard steel spindle wallows out the relatively soft alloy. It does not matter how tight the retaining bolt is done up the ...

If the bolt is bottoming out on the spindle, then tightening the bolt won't do anything. As you pointed out, you could potentially insert the correct spacer, if you could find one, into the crank to allow the bolt to tighten once again. It would be a rather special spacer though. If you are truly without scruples (i.e. if it's a junk bike and you need to ...

Spindle length and chainline are immaterial to it being Italian. The center of the spindle is at the center of the shell either way. If the chainline is good now and you're using all the same parts, get another JIS BB of the same spindle length in Italian. If you wanted to tweak the chainline, it's the same process as any square taper crank. Use your ...

Judging from your videos, it appears that the chainrings and crank are no longer connected. It appears that you have something called a one-piece crankset. If you are confident that you can learn how to disassemble it, I’d say you’re up for the repair. Once you have the crank off the bike, you’ll be able to see how the chainrings and crank arm are connected. ...

While we don't have your bike in hand, or at least a video of the issue, it sounds more like your freewheel or your freehub has failed. I suspect that new cyclists might say the gears have failed. Edit: This answer actually mis-diagnosed the problem (albeit I'd argue for good reason - it was given before videos were provided!). I'm leaving it up for general ...
