I have a Cannondale Synapse 5 Carbon, and the Tektro brakes are one of the first things I would upgrade or at least the pads to Koolstop salmons. It looks like your tires are regular Vittoria Zaffiro's. Upgrade those to some folding bead Conti GP4000's, Michelin Pro Race 3, or Vittoria Rubino pros. You can add some Conti Race Light tubes to help save some weight. You know Mavic CXP 22's are not bad wheels in my opinion, but they are not the lightest. Like others have said do not bother upgrading your components. Just keep riding and wear them out. YOU will become faster over time while riding more. As long as your bike is in the 20 pound range it will not hold you back in the least bit if you decide to race.
