Guys are you serious...?
All Cipollini frames are di2 ready. You can clearly see that this hole is intended for electronic transmission. It is just not opened up yet in your frame. Didn't your LBS tell you that? I wonder.
I could accept what you say about the bb but allow me to seriously doubt it...
No, are YOU serious?
You want me to allow you to doubt that MY frame had a BB defect? So what are you implying, that I'm lying just to give Cipollini a bad name at my own expense? I could've been hit with the 15% restocking fee for returning, and I was even ready to face it to cut my loss as the frame was unusable. However, my LBS was kind enough to grant me full refund after watching me slip a bb cup right through the shell.
Well I guess I can't no longer prove it since I don't have the frame anymore. But I'm including the return receipt so I can at least give you the circumstantial evidence that I returned it without getting penalized for simple change-of-heart return. I know I can't convince you, KGT, but I'm writing this so other readers on this forum can judge for themselves.
Secondly, that indent there, as I thought, was SUPPOSED to be a electornic wire port, and some NK1K's do use that hole. But guess what? They never drilled it on mine. Even if that hole could be drilled to accommodate Di2, why haven't they drilled it? Cipollini wants end users to drill a 5mm sized hole on a $6,000 carbon frame? and they'd still honor that joke of a warranty, right? All the rest of my frames have EPS charging port pre-drilled and rubber plugged, not to mention some kind of wire port to facilitate Di2 grommet.
Above images I linked are from road.cc Nk1k review and a fellow user on this forum. See how the Di2 cables are set up? I guess their LBS failed to mention the magical port as well.
My NK1K frameset came with Di2 accommodating cable-stop to be used at the same location as images above, at the DS downtube where mechanical cable stop is. So clearly Cipollini's grand plan to use that toptube 'hole' has been scrapped for the frame I bought, and moved on to simply using the mechanical cable stop location. That indent now is a ugly by-product of not thinking the design through, or not changing the mold design even though the intended design has veered off.
I could still drill a hole in there and use it for Di2. However, if self-drilling a multi-thousand-dollar frame without worrying about warranty was an option, I would've put EPS on my Pegoretti ages ago, and that's a steel bike.
