We are going up some road into the Mountains that they say is mostly cobblestones. Cars go up there. So I remind them of my touring bike. No suspension. But, semi knobby 35 mm tires. They tell me I'll be ok. So , I am going. I just don't care about off roading and playing in the dirt. I am a city person... Do you think a heavier frame touring bike with wider knobbies can cut it when all else are out on Mountain bikes. I have never seen this road. Hope I'll have fun .
