looking to get back into mountain biking, ive had a raliegh m-55 for several years and it treated me really well. i have hit the trail in several years. i really enjoy uphill and downhill rides, and plain trail rides. I like hitting some small jumps. I can spend around $400. I would like a nice front suspension bike, with good components, that will hold up. I hear that disc brakes might want to be avoided because they are not worth it for this price range and downplay the quality of the rest of the bike. So if this is true, i suppose v-brakes will be fine. I do not know much about what derailers or shifters are good or what kind of fork i should look for.... I went and looked at a trek 4300 and the gary fisher opie, both seemed nice, but i dont really know what i am looking at. I also saw the ibex 450 online which looks pretty nice. Are one of these bikes for me, or is there one out there i am missing that will work for me. Thanks.
