biking in the woods and mountains - what equipment is needed
I love to ride my bike and use it a lot but normally in the city and the bike, that I have is an older one (but I love it ). I would like to make a trip with some friends to the mountains and ride the bike through the woods (you know what I mean ). I can get a mountain bike from a friend...what else is normally needed. I dont want to be a professional, so dont want to spend hundreds and hundreds of dollars for one trip. Thanks for any advice.
