And a drop bar still won't make you a TDF superstar....... just so you know..... it really is the motor!

A cheap way to experiment with drop bars is to buy a set of bolt on drops, by Origin 8, available thru Niagara for sure. They really work well for what they are.

More time will definitely see more results - like Machka said - come back in 6 months and tell us how you are doing, comparatively.
