I've always liked the idea of mountain biking but I seem to have a hard time actually getting out to any trails. I am used to riding a road bike so it's really hard for me to work up the motivation to get on a mtb and ride for a while on pavement before getting to the trail.
So, I went out and got a cross bike. Took it out on what I guess you'd call all mountain or heavy xc (Burnaby mtn to any of those from Vancouver). The trails there are mostly singletrack with a few medium sized rocks, some small roots and stuff, occasionally a log or something blocking the path. I'll admit I am by no means a stellar mountainbiker. On the intermediate difficulty trails, I found myself bailing pretty frequently and often putting a foot down or taking descents with lots of braking.
So my question is this: are my bike handling skills simply too crappy or is my equipment a key factor here? Am I simply trying to take this bike on a trail it is not capable of handling?
Another issue I had was that on a descent, I hit a rock which was covered with leaves and ended up pinch flatting. My pressure was pretty low (about 30-35 psi). Does this mean I should get bigger tires or should I just open my eyes?
