If you can't afford to spend much on a mountain bike, reviewers say the Trek 4300 Disc is a good value. It has Promax disc brakes, which offer better stopping power than the V-style brakes found on most inexpensive mountain bikes, and the aluminum frame is described as strong and lightweight. The Trek 4300 Disc is a hardtail bike, so it doesn't have suspension in the rear, but 4 inches of travel in the front help smooth the ride over bumps and obstacles. The Trek 4300 Disc also includes a shock lockout, which makes it easier to power up climbs. One reviewer also claims that the fork is one of the best available in this price range. Most say the bike handles well, and the brakes have good stopping power even when muddy or wet. However, some say the tires need more grip and we saw a few reports that the rear derailleur can break easily. If cost is really a concern, the Trek 4300 (MSRP: $570) will save you some money, but it has V-style brakes.
