Campagnolo Chorus rear caliper stone damage??
Moderator: robbosmans
Long story short, had a LBS install new set of Chorus on my Oltre XR3.
I didn't check every part before I left the shop.
After a couple weeks riding, I decided to wash my bike.
All campy components were fine except the rear caliper which has 2 deep damage marks, around 5mm diameter.
It so deep it goes down to the metal.
LBS says, your rear tires threw stones onto it OR you hit some acid pool.
I had nothing to say.
I emailed Campagnolo Italy and the Hong Kong distributor and got an email back from Taiwan
"Dear customer
First at all, thank you for using Campagnolo products.
In the technical point of view from the attached photo, it seems like the rear caliper have been hit by small stones during the cycling, and according to our warranty, this is more belong to human factor causing, not fit to Campagnolo warranty policy. Due to the reason we don't sell the spare parts for replacing the caliper main body, only have to change the whole caliper.
Please request to the shop you original purchased for more help, thank you for your understanding
Thanks & Regards,

The problem I have is, one of the marks is on the 'frontal' side of the caliper, basically the stone would have had to travel at high velocity, smack my frame then bounce onto the caliper and scratch it deep down to the metal.
My frame has zero scratches around that area.
The other theory is acid, I'm actually fine, no burn marks and my bib and jersey are fine.... So I discount hitting a pool of acid haha.
Anyone experience this?

Have had a number of black finished campy brakes all I can say is the finish is very durable Also the fact that the missing finish is on 2 completely separate parts I’d be tempted to rule out a badly finished alloy part. My guess would be damage during the build such as it may have been dropped or something dropped on it.

looks like something corrosive got on it
At first I looked at this thread off my small iPhone screen.
Looking at the pictures now on my large monitor - I tend to agree that it looks potentially like a splash / drip of something corrosive.

A drop or two of DOT brake fluid from a SRAM hydro system in the shop would damage paint like that.

Rear caliper, perfectly rounded stone impacts - not likely.
I'll also go with the acidic drops theory.
I would sand the area down and just spot paint it if the shop won't support.

I’m not sure if you can purchase a single rear caliper, but you can order a new pair of Chorus calipers for around $80US if you are unable to get warranty replacement.

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

thanks guys, yeah, figured paint might be the way to go until I decide to replace it.
