Has a lot to do with the rider body surface area presented to the wind
which in your case is not bad, about like a slightly overweight DF rider
trying to ride on aero bars. DF riders have to be able to get their backs
parallel to the ground to match the natural air resistance your comfy
V-Rex provides automatically. The difference becomes most apparent
above 23-25mph and the pull away gets dramatic when the hill is long or
steep enought to get above 30mph. My ref to sl overweight is NOT in
ref to the OP, only the fact that middle aged guts tend to interfere with
a decent aero position.
I used to coast away from a friend who had a V-Rex but when he got
his Bacchetta it was almost even with him having a just perceptible
advantage. Partly faired low riders have us all beat.
Finally technique is important, there are DF riders who are just
good descenders, able to get a good low tuck and these guys
will stay right with you, until they sit up.
