Triathlon Bike for small chicks

Fitters
1

I brought a QR V-PR and I am experiencing severe neck pain when I ride longer than 50 miles. I gave them all my measurements prior to purchase and my old Tri-bike is a Guru that had 4"drop from the pads to the brakes. the new QR has a 6"drop and its integrated into the bike therefor no adjustments can be made to raise it up. It seems bike manufactures dont make triathlon bikes form small chicks anymore 5’2"

Any advice?

If this bike is at a correct seat height for you, and with all the spacers installed there is still 15cm of drop, this bike is way too small, or there is something else going on.
