I have been reading about "adventure bikes"; i.e. Cannondale Slate, No.22 Drifter, Specialized Diverge and my curiosity has been piqued. 58 years old here, ride mostly poorly paved and hilly roads, but would like the option to explore the wood's and field's roads and maybe even light cyclocross. Can an adventure bike really do it all well? Or will it be just okay and wishing I had two bikes, a road bike and a cyclocross bike?
