I used to mountain bike about 15 years ago and got out of the sport. Now I'm older and fatter, but think it's time to get back in shape and start riding again. It seems like there's a lot more manufactures out there now, so I really don't know who is making quality products anymore. Could anyone suggest a good bike in the $300-$500 dollar range. My only real criteria is that the bike is a hard tail and has disk brakes. Thanks for the help.
