All-Mountain / Enduro (AM) bike category typically provides 125-170 millimetres (5-7 inches) of rear and front suspension travel and stronger components than XC models, while still providing overall weight suitable for climbing and descending on a variety of terrain. While traditionally called All Mountain riding, this style has been adopted to the Enduro World Series. There are two formats of Enduro racing. “Big-Mountain” Enduro is mostly similar to a DH course, but is much longer, sometimes taking a full day to complete, incorporates a few climbing sections to keep riders challenged. “Gravity” enduro uses an equal amount uphill and downhill on paper, but the uphill segments are not timed. Typically, there is a maximum time limit on how long a rider has to reach the top of the climb.
In south-east Queensland, there are events such as the Gravity Enduro Series held each year with tracks that are more suited to AM bikes. The tracks include hill climbs and steep descent where more travel is often appreciated, although not usually a requirement.
As AM riding can be considered a slightly higher risk than XC, you will often see riders wearing more protection. This is mainly due to the steep descents and rocky terrain. “Enduro helmets” have lining that often extend further down the sides and back of the head providing more coverage than a standard bike helmet. Goggles are becoming a trend in AM riding and the usual lightweight elbow and knee pads are worn as well.
