Emphasis is on trail features with large air time such as jumps and drops. Today, there are a large variety of discipline oriented designs. This is highly advantageous as rolling weight greatly affects handling and control, which are very important to the technical nature of freeride and downhill riding. [2], Mountain bikes are generally specialized for use on mountain trails, single track, fire roads, and other unpaved surfaces, although perhaps[original research?] The general design was similar. Everything about this bike is beautiful. Somewhere between BMX and free-ride, designs are rigid or hard-tail with 3 to 4.5 inches (76 to 114 mm) of front suspension. North Shore bikes are much like free-ride bikes in their geometry and downhill bikes in their component makeup. In early 2009, component group SRAM announced their release of their XX groupset, which uses a 2-speed front derailleur, and a 10-speed rear derailleur and cassette, similar to that of a road bike. There are multiple companies that have hit the market with a dedicated mountain bike drive train.
