Sorry, for the beginner question.
Where I live (Ontario, Canada), I am lucky enough to have a number of packed limestone trails (former railways). Those are fairly flat and great for bicycling. They are mixed use, so sometimes they are very uneven - mostly from dried up horse tracks or farming machinery.
I am using currently, cheap sumermarket bike, and it makes ride really bumpy and uncomfortable at times. I was thinking to upgrading to proper mountain bike, but I am wondering if that would be an overkill - the trails are pretty flat. Should I go with a bike with front-shocks only, or both front and back? Any suggestion appreciated.
I also have more of a hybrid-bike - Specialized Sirius Sport, but the thin tires and, clip-in pedals make it less than ideal for those trails. It also makes me feel like I am hurting it :)
