Sent my bike in for a service and they flagged this up, they quoted £987 for a carbon repair and service which is more than the bike cost, is this serious or will I be alright? Thanks.

I’m no expert but that looks incredibly serious to me.
Lmao what. That thing is toast. Get a new bike or fix it
If they flagged it for repair, I’d listen to them.
Looks like there is some galvanic corrosion going on inside that cable hole that is bumping up the carbon layers. Yes, it is serious and yes it may cost that much to be fixed. If this bike is not worth the hassle, remove all the components and put them on another frame.
If it cost more than what is worth, do an experiment for the community and see how serious it is?
Yea that’s bad. Doesn’t look well maintained imo.
What is even going on here? It looks like the hose got sucked into the top tube somehow.
I probably wouldn’t ride that.
That will continue to delaminate with use. It’ll be okay until it *really* isn’t. Get it fixed or get a new frame. That bike is okay for the turbo trainer but I wouldn’t ride that.
Looks pretty bad. I’d buy a new frame and swap parts
Frame : Dead
Serious : Very
So you got corrosion because your battery did corrode?
Sorry mate, shit looks fucked.
From just this 1 pic it looks like galvanic corrosion from an unanodized aluminum cable stop contacting raw carbon fiber inside the routing hole. The carbon is delaminating, causing that bubble.
Yes you can still ride it… for right now, today… but without resolving/cleaning the problem this will only get worse… as far as safety, your frame isn’t going to explode. It’s just going to keep bubbling and eventually crack.
Also your shifting must be crap/always needing adjustment, yeah?
The £1000 repair quote presumably includes the immediate repair with a new cable stop and paint/cleanup and a warranty/liability protection. If the estimate is from a bike shop/dealer and not a frame repair shop it probably also includes the dealer’s fee for coordinating it.
In a technical sense it can be functionally fixed for far less than that — for starters drilling out the other cable stop at the front of the top tube and running continuous housing, or running external full housing — but the immediate corrosion/delam has to be cleaned up and resealed first. There are very competent professional mechanics who can do this functional fix fairly easily.
If you took it to a frame repair shop you should heed their assessment, that’s what they do. If you want another opinion that’s totally fine too, but *take it to another professional to inspect it in person*.
If you’re concerned about safety, coming to Reddit to hear what you want, you’re going to hear what you want but might not get what you want in the end.
Remiss not to note this frame — again, if the corrosion/delam is cleaned up and resealed — is 100% fine for electronic shifting too, and a shifter/derailleur isn’t £1000, so try to find a good home for it if you’re moving on from it.
Ride safe, have fun, be nice. ✌️
It is almost always serious when you see a crack on a carbon frame.
I am no carbon expert but if that came into my shop I would tell them not to ride it unless it had been checked by someone who was and given an all clear. To say a carbon repair in that area is challenging is probably understating it so the fact they have quoted this price doesn’t surprise me.
I have said many times on here that carbon is a great material that can be repaired but sometimes the cost of doing so can be more than a replacement
Ask the shop. Don’t trust them? Of course they’ll say, “No.”. Nobody will tell you, “Yes, ride it.” Not even here.
