I am new to mountain bikes. I have riden road bikes prior and hated doing it. Always felt very uncomfortable on a road bike. I am thinking about a steel frame bike for my first mountain bike. I believe that the steel would be much more forgiving to vibration. I remember the awful vibration of my old Trek 1500 on the road. I know that steel will be heavier but the trade off, I believe, will be worth it. I am considering the Jamis Ranger XR as an entery level with the plans to upgrade components rather quickly if not at the time of purchase. Any opinions would be greatly appreciated. Thanks
