Yes. There are other and significant differences, of course. The hybrid had a heavier, triple front setup, the road bike is a lightweight, standard 53/39 setup. The tires on the hybrid were slightly wider, slightly heavier rims, tubes and sidewalls compared to the 23-700 Mavics on the road bike, which weigh next to nothing. The aluminum frame on the hybrid worked great - never broke in 15 years of riding - but it weighed perhaps 30% more than the carbon frame that replaced it.

So yes . . . other differences, not just weight. But most all of those other differences ALSO included weight savings in the recipe. Thanks.
