Bent spokes?

So the chain fell of the back of the cassette and into the wheel... The spokes aren't broken but they are slightly bent, do you think I need to repair it or should it be fine it's own condition? (I can take pictures of it if needed but I believe the angle change is from 180 (straight on the spoke itself) to around maybe 120-150 but it's a notch if you get what I mean... Also (carbon frame) but the fork is a creaky (or squeaky however you want to call it)... any suggestions?

I've not seen a spoke that was merely bent fail. but it's possible that a bent spoke will make truing a bit more quirky. If the notches are actually cuts they could eventually fail, but likely not soon.

Don't tell me what "should" be - either it is, it isn't, or do something about it.

If you think I'm being blunt take it as a compliment - if I thought you were too weak to handle the truth or a strong opinion I would not bother.

Please respect others by taking the time to post clearly so we can answer quickly. All lowercase and multiple typos makes for a hard read. Thanks!

Are these steel spokes? If so, they're wire and a bend won't make much difference if the tension is correct (= so high it straightens it). If they're not steel, I don't know.

the bent spokes are not just bent, they will have notches in them... they do break at the notches.
i have seen many broken spokes at the bend/notch caused by chain derails... i replace any bent/notched spokes as soon as possible...

if the spokes break, the wheel goes out of true instantly, sometimes bad enough to end the ride that day... there is no guarantee that the spokes will or will not break.

Ignore it for now because there's nothing you can do about it, short of rebuilding the wheel which isn't necessary yet.

Eventually (probably very eventually) a spoke will fail, not because of the bend, but because of any notch the chain may have cut into it. If and when that happens, you'll deal with it as you would with any broken spoke. But that will happen, if it happens long after you've ridden this wheel for miles, and maybe never.

This is exactly why it should not be ignored.

There are no subways, taxis, buses or Ubers where I ride.

Not sure where the OP rides or if walking the bike home is an option for him but it isn't for me.

Yup. I've seen lots of overshifted wheels where the chain grinds the spokes up pretty bad. They may not fail to day but they will probably fail at some point.

If the spokes are notched I would replace the ones that are. The outbound spokes are the ones that will be cut when the chain gets caught inside the cassette.
Now you can see the need for a spoke protector.

i install the ones that are the same diameter, or close to that, as the cassette or freewheel... they don't look bad, and will protect the spokes in the event of an overshift.

Daniel's CX bike even has one on it.

It's only 1/4 of the spokes, and if you change them one at a time and keep the wheel true you don't have to know anything about wheel building.

I agree the spokes are damaged, and they should be changed as soon as is convenient.

My own experience is that failure (or failures in my case) are a when not an if. You will have to judge whether or not you can accept this risk. Two or three spokes failed before I gave in and had the wheel rebuilt with all new spokes.

Another point is that low spoke count wheels are more likely to become unrideable after a spoke breaks than, say, 32 or 36 spoke wheels. And brake calipers with cam-type cable releases are explicitly designed to accommodate this type of problem.
