Pics aren't great but maybe they can give some idea.. Cracks don't seem deep, but still worrying. How could a crack like this happen, haven't crashed it and only have around 1000 miles on it since purchased at the end of May.

Take the best possible pictures you can and send them to Bianchi direct.
Since this is the Countervail Tech, i would not leave it at a local repair shop or such as Calfee.
I would mail or call Bianchi and see to it to be connected to the correct department.
Bikes:

Ax Lightness Vial EVO Race (2019.01.03)
Open *UP* (2016.04.14)
Paduano Racing Fidia (kind of shelved)


Ex bike; Vial EVO D, Vial EVO Ultra, Scott Foil, Paduano ti bike.

I am having a very similar situation. I just noticed cracks in the clear coat on my seatstay while polishing the bike yesterday. There is also a delamination bubble next to the cracks. I did the coin tapping test and it sounds like it is probably damaged carbon under the clear coat. I am on my way to my LBS that sold me the bike. Luckily I do have an n + 1 road bike to use during the warranty and/or repair process. The frame is a Pinarello Dogma 65.1. It was not crashed.

It's all downhill from here, except for the uphills.

When did you buy it? Pina warranty is only 2 years (3 if registered).

It is registered with Pinarello/GitaBike and within the 3 years. It was purchased in March 2014, so 2 years, 4 months.

I had a similar break on my Canyon a while back. I stripped the frame down, boxed it, sent it to the UK for professional repair and was riding it again within a month.
The repair was peanuts cost wise and I honestly cannot tell where the patchwork/repaint was actually done.
Just rode the Maratona dles Dolomites on that frame and it has thousands of hard kms in it since the repair.


Within a month?

But this thread was started four days ago :lol:

Hoisted by your own petard there!

Jesting, I know what you mean. The situation isn't so simple, clearly the first step is to enquire about warranty and canvas opinions about what happened to it. Sure, if I crashed the bike, or knew how the damage was caused then I could have skipped all that. Anyway the carbon repair guys in the UK who we would both use are fully booked right now anyway. Couldn't even start a repair anytime this month.


Apologies. Reading this on a mobile phone led me to believe it was originally posted in June, not July. Note to self, get reading glasses.

@frogman have you tried riding on it? Does it feel different. I was busy this week and didn't sort myself a cheap winter bike which is what I was meaning to do anyway. So now I'm in the situation where the missus wants to do Rapha 100 tomorrow and I've only got my broken frame.. was thinking to tape it and go easy with her.. not sure if it'd make it. I mean it's already broke so..

@wheelsONfire didn't think of that actually, but yes maybe speaking to Bianchi directly could get me somewhere. I'll have a shot next week :|

I wouldn't trust tape to hold your weight.

Just joined this forum.
My brother and I bought 2 Oltre (XR and XR 2). My XR2 seat stay broke in 12 mths- replaced by Bianchi and broke again in 6mths!!!!. My bro XR broke in 3 yrs. all breakage in same place. Seat stay non drive side

We cycle only 2000km per year!!!!. Weight 72kg. Only road cycle.

I think there is design fault. Just check out the latest XR4. The seat stay is much much beefier
