Hey Bikes & Drums, I wouldn't expect a big jump in speed going from hybrids to roadbikes.The main question to yourself is are you more comfortable sitting upright or are you comfortable in the drops?Your main change in speed will be from being more aero on a roadbike.Its just easier to improve because you can 'use more of the bike'.Getting faster is only obtained by going faster.I'm happy being a 14 mph average.I may be slow but I get there,and I SEE the sights. Ride how you want to ride.
