Mountain biking glossary
If you're new to mountain biking some of the jargon might be a bit confusing. We've provided explanations of a few of the more common words you might hear below:
Bikes
- 
Full sus: a mountain bike with suspension systems at the front (in the forks) and rear. Short for ‘full suspension’. 
- 
Hard tail: a mountain bike with suspension at the front, rigid frame at the rear. 
- 
Granny ring: the smallest of the front chainrings, which comes in handy on the steepest climbs. 
- 
Granny gear: the lowest gear you can ride. 
Trail types
- 
Cross-country: usually a circuit of trail that includes a combination of singletrack and forest roads. Can include more exposed land. Often written as ‘XC’. 
- 
Downhill: a very steep, fast, technical course, black-graded, often ridden with a specialist bike. Often written as 'DH'. 
- 
Freeride/fun park: areas of trail with lots of jumps, berms, camel bumps, drop-offs. 
- 
Singletrack: narrow trail of varying width, often through trees. 
Trail features
- 
Berm: a steeply banked corner which it’s possible to take at speed. Trails can be described as 'bermy'. 
- 
Bomb hole: a large crater-style hole. 
- 
Boulder garden/rock garden: a section of the trail strewn with stones and rocks. 
- 
Camel bumps: two jumps placed one after the other with a gap in between. 
- 
Double: see camel bumps. 
- 
Drop off: steep and sudden drop in the trail. Often a vertical drop down the side of a rock. 
- 
Gnarly: a section of trail that’s especially rough and rugged and often steep. 
- 
North Shore/timber trail: raised timber trails often referred to as 'North Shore' having originated in Canada, where mountain bike trails are built across boggy ground. Can take trail across loose or wet ground. 
- 
Off camber: opposite to a berm, when the slope hinders cornering at speed. 
- 
Powder run: dry, dusty stretch of trail. 
- 
Switchback: when the trail turns tightly on a climb and goes back on itself. Also known as a hairpin. 
- 
See-saw: just like in a play park, but for bikes - go slow in the middle to allow the see-saw to drop gently! 
- 
Skinny: a wooden beam, roughly 6 inches or less in width, raised off the ground. 
- 
Step down: a much less severe version of a drop-off. 
- 
Step up: a step in the trail that requires you to lift the front wheel first, quickly followed by the back wheel. 
- 
Tabletop: ramped bit of trail leading to a plateau, with a ramp down the other side – or two camel bumps with the gap between them filled in.
