Well that's one way to ruin my weekend. I just noticed some damage to the CF around the hole in the downtube where the Di2 cable enters the frame. It's a Rose Xeon CDX which is a couple of years old and has been well looked after. I've contacted the manufacturer for their thoughts, apparently the frame has a 6 year warantee which is good at least.
I've attached some pictures, bearing in mind the stresses that go through the head tube/down tube I'm worried this means the frame is a write off. Has anyone experienced anything similar?
At least I've got my winter bike to tide me over
