Over the years I have experimented with arranging a few of my bikes with Hybrid components - In the long run it did not work for me - When you need a mountain bike it must be a mountain bike even if its a cheap one - And a road bike is best for the road - The closest to the two for functionality is the cyclo cross bike...
In other words when your on a Hybred on the road you want to go faster - And when your on a trail with the Hybred you want to go faster - So if your on a Hybred you end up going slower...
But many riders will defend their Hybred to the end as it should be...
