I don't know how much the value of your bike is, but try putting your bike on Craigslist and state that your looking for offers. You never know someone might be interested and shoot you a decent offer. Your current bike setup looks good to me, I don't know if you truly want a new bike but if you do the sale on the Mark V is definitely a good deal. Considering that its roughly going to cost you around 450-500 including shipping for an excellent frame and solid build for a complete. Have you test drive one? A cheaper option is also to go with the Kilo TT. If you can test drive both that would truly help you with your decision.
