What you're telling me suggests a certain disconnect between the sales department and the shipping department. My salesperson was "Katie". The inclusion of spares was something I dealt with in specific terms. I asked for (and paid $5 for) an extra derailleur hanger. Likewise with an extra seat post clamp (which she forgot on the final invoice, and has promised to include free of charge). I don't know if being specific screwed up any hope for getting a grab-bag of spares, or not.
I'm not planning to use a front derailleur, and my rear mech will be SRAM AXS, so the only reason I'd have for removing the bottom plate would be to increase access when routing the rear brake hydraulic hose, though I suspect that won't be necessary.
My gut tells me that querying "Katie" about the contents of a bag of spares would be fruitless...or perhaps even counterproductive.
I don't have any issue with mentioning to her that I heard from someone else that the guides on the bottom bracket cover can be fragile and broke during installation, and that I would love to have a spare. We can see what happens.
While we're talking I have a couple of questions based upon your previous response. Do you think the SRAM 12-speed rear mech for a 10-36 cassette will conflict with the chainstay? And when you talk about the trouble you had with the rear thru-axle on the cassette side, do you mean on the cassette side of the bike (right) or the cassette side of the right chainstay (left)? Was the part you swapped part of the derailleur hanger assembly on the right chainstay, or something else?
My frame has to be painted so it's not likely that anything will be shipped for a while.
That works for me
I did not specify the exact spares, other than the derailleur hangers. As I've read previously with the 696 frame they have some sort of "spare parts bags" that are included and I got 2 of them. In both bags were 2 derailleur hangers, several plugs, screws, cover plates and the screw in bit where the thru axle goes In.
This is easy:
Green circle is the part. Blue arrow the screw which attaches it to the frame and the red arrow the tip of the axle. Just unscrew axle, undo screw, replace plate and vice versa with new plate.
As to the sram rear derailleur, don't know. If there are no particular handles it should fit I guess.
