SRAM etap confusion?

[bikeman]

currently have been riding my IF, Colnago steel and Bianchi (scandium/carbon) bikes with campy and sram.

Thought it was time to upgrade to new bike that i always wanted. So i have purchased the Moots VaMoots frame. this frame is setup specifically for electronic.

The electronic stuff is a little daunting to understand. i build my own bikes so pretty confident in mechanics, upgrading and or fixing. But this electronic stuff I’m baffled a bit and uncomfortable.

I would like to use existing parts i have to cut cost down purchasing either Shimano Ultegra Di2 or Sram Force ETap. Heres what i have and would like to use:
– mechanical disc Avid 7
– 10 speed – shimano dura-ace or sram crankset 50-34
– cassettes – 12-28, 11-30

Question:

How much of mechanical components can one use to integrate with these electronic systems? Will the front and rear derailleurs from the electronic groupset work with my chankset and cassettes?

Hope my description is not confusing as it is to me

I don’t have a super helpful answer considering that I’d ask my shop to take care of something like this. However, I wouldn’t be surprised if it’s hard to find something like an eTap derailleur or shifters that are 10-speed, considering that now there’s 11s and 12s. It might be worth upgrading your crankset/cassettes (the latter of which might mean new hubs/wheels?) for wider availability of 11s parts. Hopefully I’m wrong, and you can easily source 10s components and save some cash though.

I’m not aware of 10-speed sram etap components. First gen Di2 might’ve been 10 speed compatible. I’d also be concerned about mechanic disc calipers – they generally make the levers to be compatible with hydraulic disc OR mechanic rim calipers. I do not know if the lever pull for mechanical disc and mechanical rim calipers are the same.
