Your tandem has 130mm rear triangle width? Most tandems are wider by at least 5mm, usually 10-15mm.
I would be concerned about the axle metallurgy at that price, especially in a tandem where...

My two CF bars have warning sheets sent with them by the maker saying they should be replaced in 3 yrs.

Local experience with "older" (ie pre 11 spd) Mavic wheels has been variable but not good for the availability of OEM
specialty spokes.
Best bet is to consult the best respected bike shop in town.

Thomson has 2 and 4 bolt stems. Somewhere on the Tandemgeek blog in the past 2-3 yrs is a pix of a somewhat similar
