Trek Mountain Bike |

69er Many newer mountain bikes have a full suspension design. In the past, mountain bikes had a rigid frame and a rigid fork. In the early 1990s, mountain bikes started to have front suspension forks. This made riding on rough terrain easier on a rider's arms. The first suspension forks had about 1½ to 2 inches (38 to 50 mm) of suspension travel. Soon after, some frame designers came out with a full suspension frame which gave riders a smoother ride throughout the ride.

Newer suspension frame and fork designs have reduced weight, increased amount of suspension travel, and improved feel. Many lock out the rear suspension while the rider is pedaling hard or climbing, in order to improve pedaling efficiency. Most suspension frames and forks have about 4 inches (100 mm) of suspension travel. More aggressive suspension frames and forks made for downhill racing and freeriding have as much as 8 or 9 inches (200 or 230 mm) of suspension travel.

Many riders still prefer to ride a hardtail frame, and almost all mountain bicycle riders use a suspension fork.

Cyclists choose mountain bike hardtails for their low weight, durability, agile feel and precise handling. Whether it’s for race, recreation or pure pleasure, Trek mountain bikes deliver the right choice when tires hit the dirt.

Bikes with front and rear suspension allow greater control and comfort in all conditions, but not all full-suspension bikes are created equal. Only Trek mountain bikes give you ABP, Full Floater, and EVO Link suspension technology that is tuned for each category.
