This is what I currently own (with 23c tires though):

This what I'm thinking of purchasing:

What I'm wondering is how much of a speed increase I'm going to see simply switching bikes. I know the engine (me) is the biggest factor but will I see a 10%? 20% 30% increase in speed?
Any thoughts is greatly appreciated. |
I don't know how much you'd gain if you're already using road tires on your current bike. You will be more aerodynamic, and have better shifting for sure. Im guessing the road bike will be a little lighter as well.
The gearing on the giant is stronger 52-11 vs 50-12 on the diamondback road bike. At 52-11 doing 90 rpm you'd hit 53.6 kph, at 50-12, you'd do 47.2 kph, assuming you're using a 700c x 23 tire. However, can you crank that on a heavier, less aerodynamic bike? Road bikes put you in a position to generate power. If you get more aero, you have less wind resistance, and can generate more power.
I didn't really answer your question, you asked about speed. If you are looking for a bike to take out on the hwy, then I'd say get a road bike. No question. Go test ride a similar spec'd bike somewhere and see how it feels to you.
