Good clean, Found damage

[Liamjc90]

So i finally gave the bike after 3 months of daily riding. Yes i know long over due but it didn't seem that bad. Photo below is a after photo forgot to take before.

But then i found this on the cassette, could it cause any problems or will it need changed?

Any help or advice appreciated.

It could cause issues but, tbh, I'd be as concerned at the state of the chain as well. You might think that it didn't look that bad before but, as you've found, a clean is about checking the bike over as much as anything.

The teeth on the cassette look ok to me, well, apart from the 2 missing ones, that is, so if it's not slipping the cassette probably just needs a good clean and a regular dose of lube. There's a good chance that the chain was involved in whatever sheared off those 2 missing teeth so I'd give the chain a thorough inspection for damage after giving it an equally thorough clean.

If it was me I would replace the cassette. Is it a hyperglide chain? Not that that would have caused the breakage.

Replace chain and cassette.

Replace chain and cassette.

I'd also check chain rings for wear as well. That lot looks knackered and it might have worn the chain rings too

No dont think its a hyperglide chain, the bike wasn't expensive and i'm planning to upgrade after winter. I was hoping that i could just leave it and it would be fine. I haven't noticed any damage eles where apart from the rust the chain looks fine and the chainrings still look good. so i guess my real question will it survive the winter?

...so i guess my real question will it survive the winter?

only one way to find out really.

 

[Liamjc90]

Good point. I may just price up the items and take the plunge, so on a related note would it be difficult to change had not real experience with bike? Im a mechanical fitter by trade so usually quite good with this sort of thing.

Easy to change but you will need some specialist tools (http://www.parktool.com/blog/repair-help/cassette-and-freewheel-removal).

If you don't want to spend money I'd be tempted to ride it and see if the chain slips on that cog - if it does you could always just avoid using that particular cog! Does demonstrate the need for fairly regular cleaning and lubing tho'.

I have been riding it. im not sure when it happened exactly, it was some time in the last month. I haven't noticed any slipping and i do use that cog for climbing some smaller hills. Im looking at around £40 for cassette, chain and tools.

If it ain't broke why fix it.

I'd join with everyone else saying a new chain and cassette. I'd also (cheekily) suggest that slightly more frequent oiling of the chain would be beneficial. My current chain (same type as yours) on the knockabout bike is almost a year old now and has been ridden through mud, rain and road salt but it doesn't look nearly as bad as that.

It can be done for slightly less than £40:
Chain
Cassette
Chain Whip
Cassette Tool

Total cost £32.58 (at the time of writing) with free delivery.

In addition to Phil's most excellent links, if you want a bit of a ghetto fix rather than buying a chainwhip you can hold the old cassette to stop it spinning with a pipe wrench, as when putting on the new cassette and lockring you dont need a chainwhip anyway.

My last chain/cassette replacement +chain tool cost about £22 and i splashed out on a £10 chain

 

[Liamjc90]

The price isn't really an issue i have this list so far.
Lubricant
Chain whip
Cassette tool
Chain
Chain tool
Cassette
Anything else i might need or should that do the trick? I was using 3 in 1 oil before but guess its time to get something a bit more purposeful if i going to replace the lot i dont want it to end up like this again.
