The A-Z of mountain biking jargon, with helpful definitions

Mick Kirkman / Our Media


Seasoned mountain bikers may sometimes appear to communicate using their own set of words and expressions – some borrowed from other action sports, such as surfing and skateboarding, others unique to the world of fat tyres.

If you’re an experienced rider, you should be well versed in the lexicon of MTB. If you’re not, it’s time to become fluent.

Here, we've provided the definitions of some essential words and phrases from the mountain biker’s dictionary.

The mountain biker's dictionary

Case

Mountain biker jumping at BikePark Wales
I don’t think I’ll ever have BK’s style, but I’m airborne! Andy Lloyd / Our Media

Meaning: That awful jarring feeling when landing from a jump but not making it all the way onto the downslope, typically tagging the top or back of the downslope with the rear wheel of the bike.

Example: “Ouch, I just cased that landing so hard.”

Gnar

Loic Bruni jumping his Specialized Demo 11 through a rocky section on a World Cup track.
The revised suspension kinematics should help smooth rocky sections of track out and let riders go faster. Probably not as fast as Loic Bruni, though. Specialized

Meaning: Tough terrain that’s risky to ride, particularly rough descents filled with large holes and covered with rocks.

Example: “I’m out here carving the gnar.”

Gnarly

Netherlands' Mathieu Van Der Poel crashes during the cycling mountain bike men's cross-country event during the Tokyo 2020 Olympic Games at the Izu MTB Course in Izu on July 26, 2021

Meaning: Terrain or an incident that is particularly, wince-inducingly hardcore, extreme and scary.

Example: “Your crash was gnarly.”

Huck

Two MTB'ers jumping at Farmer Johns MTB Park, Greater Manchester
Some of the bigger jumps are pretty sizable, and there are some cool new-school feature, Mick Kirkman / Our Media

Meaning: A move that involves pulling up hard on the handlebar and launching off a jump or drop with an unknown chance of success, usually preceding a sketchy landing.

Example: “I just sent that huck so far.”

Loamer

Norco Sight VLT TQ C2 on loam
Norco Sight VLT TQ C2 on loam Norco

Meaning: Natural trail that’s fresh and still surfaced with organic matter. This so-called ‘hero dirt’ is soft yet grippy, making it a blast to ride. Loamers stop being loamers when the surface has been scraped away, leaving hardpack, roots and rocks exposed. Loamers are highly prized for riding due to their scarcity and inherently temporary nature.

Example: “I’ve found a new loamer.”

Mullet

Starling's Big Bird uses a mega-mullet wheel size setup with a 32in wheel up front and a 29in at the rear Scott Windsor / Our Media

Meaning: The iconic mullet haircut is 'business in the front, party in the back', referring to the short, orderly fringe and free-flowing, devil-may-care locks bouncing merrily around the neck. Mullet bikes similarly have a larger front wheel for smooth-rolling speed and a smaller rear wheel for style-boosting agility.

Example: “I just mulleted my bike.”

Nadgery

Male rider in blue top riding the Cube Stereo ONE77 C:68X TM 29 full suspension mountain bike
While the ONE77 doesn't shy away from tackling the rougher, more technical tracks, it's not where it shines brightest. Andy Lloyd / Our Media

Meaning: Trail features that are awkward, technical, rough and slow.

Example: “That descent is so nadgery.”

Roost

Race Face Era wheels being scralped through a turn kicking up dust.
Race Face's new Era wheels set out to delivers the best aggressive trail/enduro wheels by having the making the lease compromises through compliance, impact resistance and weight. Race Face

Meaning: Originating from motocross, roost is the material thrown into the air by a rider.

Example: “You just hit me with a load of roost.”

Send

Bernard Kerr in mid jump at BikePark Wales
BK throws a lazy T-bog (toboggan) for the camera, leaving Tom agape. Andy Lloyd / Our Media

Meaning: Usually associated with getting big airtime. If you hear a rider exclaiming that they’re going to “send” something, it means they’re about to hit it with full effort, in a reckless manner, hoping for success, rather than expecting it.

Example: "I just sent it off that jump."

Schralp

Cotic Flaremax skid
Skid-approved. Richard Baybutt

Meaning: Sometimes called a cutty, a schralp is an onomatopoeic term that describes hitting a turn in such a way as to tear up the ground. Speed and aggression are key here, denoting skill and confidence in your cornering ability. Caution: Can enrage trail builders.

Example: "I just schralped that turn so hard."

Shred

Vitus E-Sommet being ridden.
They clearly reckon the E-Sommet is prime for shredding! Laurence Crossman-Emms / Vitus Bikes

Meaning: An older term, but still a popular one, thought to originate from surf and snowboard culture in the 1980s. In MTB terms, it refers to ‘tearing up’ (not literally) the entire trail or mountain. A 'shredder' is a skilled rider.

Example: "I'm ready to shred today."

Sketchy

Male rider in white top riding the Merida Big.Trail 600 hardtail mountain bike
With its modern shape, I was happy tackling steep and technical terrain on the Big.Trail. Russell Burton / Our Media

Meaning: A feature or trail that’s doable, but only just, requiring you to ride on the very edge of control. Usually accompanied by a sense of surprise that you got away without a crash.

Example: “That was so sketchy, I can’t believe I rode it out.”

Steeze

Whyte Secta S hardtail mountain bike being jumped off a drop on a trail centre descent.
Get the Secta S pointed downhill, and it really lets you get motoring.

Meaning: A conjunction of the words ‘style’ and ‘ease’. Used to describe a move or rider demonstrating both effortless smoothness and control.

Example: “That whip was so steezy.”

Stomp

Cropped shot showing downhill bike on dusty, rough trail in Queenstown Bikepark, New Zealand.
Even on the roughest trails Rob could find, the drivetrain remained quiet and worked consistently well. Callum Wood / SRAM

Meaning: To complete something with confidence. Often used when landing squarely and securely on the pedals after a trick or feature.

Example: “I just stomped that black run.”

Whip*

Saracen Myst Team whipping
Saracen Myst Team whipping Saracen

Meaning: To send the bike sideways in the air. The further you can get your back wheel and body around, the better. Whip-off contests are held to find the rider who is most accomplished at this difficult move.

*Not to be confused with tailwhips, where the bike rotates around the headset while the rider holds the handlebar.

Example: “Did you see the whip that grom just did?”
