To be honest, this is not completely true. I own 1 Andean and have recently bought one from the Dutch distributor of sram/zipp as they used this one as a show model on expo’s.
Both bottom brackets were the original one placed bij DB when ordered.
They are impossible te remove. We have tried literally everything. With some very experienced mechanics from Shimano as well and at the end we just stopped since we didn’t dared to put more force on it te remove it.
In our shop it is really the only bike where we didn’t het the bottom bracket out, it was just that tiight.
My tenure at Diamondback ended a couple of months ago, but prior to that departure, I would have been the person at Diamondback handling a complaint like this, and as mentioned up thread, such a complaint was never made during my tenure. You may have contacted Diamondback after my departure, and I can't speak to the experience that you might have had at that time.
So, having said that, and assuming that you
didn't make contact with whoever is filling that role at the company presently, just a point of process here; Folks really need to talk to the manufacturer when they encounter things like this. For a couple of really important reasons.
1 - if this scenario had come across my desk, I would have told you to - and in fact requested that you *please* - use the force necessary to push that stuck BB out of the frame. I would have offered to send a replacement frame if this had resulted in any damage (which I doubt, frankly. The plastic shell of those BBs is much less robust than the carbon of the frame). This would have been resolved one way or another, and you wouldn't have to worry about it.
2 - if the manufacturer doesn't hear about problems like this, they never find out about them. N = 1 isn't particularly meaningful, but N = 3 has much more impact. One of the biggest reasons I would have asked you to take that BB out as mentioned above would have been to get accurate measurements of the BBs on the frame(s) you have to check and see that they conform to the design standard. If they did not, I would have replaced them. Frankly, my guess is that they likely do, and that this may have led to a recommendation against using a particular manufacturer's bottom bracket that our internal testing had shown to have a larger diameter than that offered by other manufacturers.
That is all, of course, talking about what I would have done when I was running the program in question. I am no longer in a position to make any such promises or offer any such recommendations in an official capacity.
