To expand on my question...
has anyone ever changed a mountain bike into a sort of cross bike ? I don't plan to race or anything, I mainly want to ride for fitness, and some local commuting trips.
I will be 75% on the roads, but would like to be able to hit gravel or dirt trails which I can't on my road bike.
The trails I will be on are not hardcore MT bike trails, just gravel or non paved Multi Use trails.
I really like drop bars on the road.
I'd like a rear rack.
I have a early years stumpjumper, that I am thinking of using for this purpose. Change the bars, use some trail tires, and ride it where ever I like.
Is this absolute crazy thinking ?
Any recommendations for shifting ?
