FT. Brand new Zipp 808 (dimpled, non-FC) for 54 "ish" cm frame

Looking to trade brand new Zipp 808 dimpled wheelset (tubular) for a 54 cm top tube (+/-). I have stack and reach numbers needed depending on frame.

what bike brand and road or TT?

Would you sell instead?

I have a 56cm 2013 Felt FC if that interests you.

For the right price I would sell. Open to MTB, CX or road.

I have a mint condition Cannondale CX9/ CAAD9 CX Tim Johnson edition, Ritchey Fork, white, yellow, and silver 9 ball paintjob. size 54.
