Ok people I have a $400-$600 question. I have looked around and can get an Iron Horse Warrior Expert for $490. My only concern is that I am new and have never heard of this brand. How do their frames hold up. I plan on doing mostly trail riding with the occasional crazy stuff. I also have ridden the Trek 4900 and Specialized Rockhopper. It seems to me that for the money the Iron Horse is the best deal (all Deore components with Hayes Mechanical Disc). The other two only have Deore Rear Der. and then Alivio stuff. Should I even be worried about the components between a Deore and Alivio? I just want to make sure that the bike I buy will hold up for the next few years and if I really like the sport then I will go to the next level and go for a full suspension bike.
