There was an article recently that pointed out that your money is better spent on aerodynamic helmets than it is on skinnier tires/wheels. It also said that
it is more aerodynamic to have your water bottle cage on the seat upright tube
instead of the angled tubes.
Lastly, and least useful was that gloves create a lot of aero resistance.
I just reread your question; sorry. A different kind of bike will surely increase your speed.
maybe one of the lighter hybrid bikes? like the top of the line Raleigh hybrid (look mine is for sale in the for sale part here)
