CYCLING TERMS

(One - Bye) Also known as 1x.

A drivetrain that uses a single chainring as the input gear and multiple cogs for the output gear. Very popular on Gravel and Mountain bikes. A 1x drivetrain simplifies and lightens up the bike by removing the need for a Front Derailleur, front Shifter, front Housing and multiple Chainrings.

The name '1 By' is a vernacular derived from '1 By 10' where 10 would be the number of cogs in the output gears.

(Two - Bye) Also known as 2x.

A drivetrain that uses two chainrings as the input gear and multiple cogs for the output gear. Very popular on road, hybrid and recrational bikes. 2x drivetrains provide more gearing options for ease of use over all types of terrain.

26 Inch wheels used to be the standard mountain bike wheel size. Now 26 inch wheels are commonly found on kids' mountain bikes, some recreational bike and fat bikes.

27.5+ wheels are the same diameter as 27.5 wheels, but use a wider tire. These are commonly used on mountain bikes, they are fast rolling and agile.

27.5 wheels are 27.5 inches in diameter and are commonly used on mountain bikes. These are also 650b wheels, and sometimes used on road bikes made for shorter riders or kids.

29er wheels are 29 inches in diameter, these are commonly used on mountain bikes. They are fast rolling, and roll over obstacles with ease.

700c wheels are commonly used on road and gravel bikes.

Weight, stiffness, aerodynamics, and vertical compliance: finding the correct balance between the four is key to optimum ride quality. BMC adjusts geometry, carbon lay-up and examines frame cross sections to try to do just that - using computer generated testing. It reports having tested 34,000 frames in this way over the course of just one year. The result is frame constructions which it feels hits the target.

Short for Aerodynamic. An Aero bike is a bicycle that is designed for maximum aerodynamic efficiencies.

A sealed air cartridge usually found in suspension forks and shocks on bicycles that acts as temporary power storage when the bicycle experiences an impact. In contrast to a coil spring or elastomer spring, the air spring is preferred in many suspension cases due to it's high tunability, extreme light weight and progressive spring power.

A metal material used in many bike frames. Alloy combines multiple metals to provide better properties (strength, weight, corrosion resistance).

A Specialized Innovation. ANGi is a helmet mounted safety sensor that pairs with a Smartphone App. ANGi does live tracking, crash detecting and it is a safety beacon. ANGi measures forces that occur during crashes even if your helmet doesn't hit the ground. When ANGi detects forces of a dangerous level it triggers an alarm on the paired phone. If the alarm is not stopped within a period of time, the app notifies designated emergency contacts and includes your location. ANGi is included on some Specialized helmets, and sold as a standalone item. ANGi is compatible with most cycling helmets.

The angle at which the front wheel approaches an obstacle. A larger angle of attack means that 'rolling over' said obstacle will be easier.

Bearings designed to take load in both radial and lateral directions. Commonly used in nicer quality bottom brackets and hubs. Usually used in all quality level headsets. A common cup and cone style hub is a perfect example of an angular contact bearing.

APS is BMC's dual link suspension design. It offers what they believe to be the best balance between pedaling efficiency, braking performance, and general suspension performance for XC racing and beyond.

To jump off your bike to avoid danger, or the fear is overwhelming, or to avoid an obstacle last minute. 'I was going to ride the expert trail but I bailed at the last second to ride the beginner trail.'

Very commonly confused with asteel ball.

A bearing is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts. Literally 'bearing' a load. Common types in bicycles areball bearings,roller bearingsandangular contact bearings. It is very important to keep your bearings clean and free of debris. Regular bearing maintenance will greatly prolong the life of your components.

For the absolute best bearing performace, useceramic bearings.

Bikes with belt drives do not use standard chainrings or chains. Instead their drivetrain uses a belt with notches to power the bike. Belt drive bikes are great for riding in bad weather or commuting since they are low maintenance.

A banked turn that has a dirt or wood along the outside edge of the corner providing more surface area to ride around the corner. Riding the berm allows riders to go into turns with more speed and continue to gain speed.

Bibs are a type of cycling shorts. They feature a chamois, but they get their name from having suspenders built in. Bib shorts are popular for their increased comfort, since they do not have a thick waistband and are held in place by the suspenders.

Bikepacking is camping via bike, or backpacking on a bike. To bikepack, the rider uses an assortment of bags and mounts to contain all of their tent and gear on their bike and then ride the loaded up bike to campsites.

Short for Bicycle Motocross. BMX is a style of riding, either BMX racing, or freestyle (tricks and jumps) riding.

A Specialized Innovation. Body Geometry (BG) is the term for the science and engineering Specialized does for all of their items that connect you and your bike. Gloves, grips, shoes, insoles, shorts, and saddles are all items that are created using BG science to improve comfort, increase performance and reduce the chance of injury. Specialized partnered with expert doctors to develop products focused on proper ergonomics based on SCIENCE! And to save men from cycling related ED.

A Specialized Innovation. Brain Technology is used on some Specialized mountain bikes with suspension. This Technology knows the difference between pedaling force and bump force. It keeps suspension firm on smooth terrain and switches suspension to fully active the instant things get rough without needing to use lockout switches. The all-new Brain is still in a class by itself when it comes to instantly and automatically adjusting suspension from firm to active to maximize efficiency and control.

Brakes are the devices that allow the rider to slow the bike or come to a stop. Bicycle Brakes convert kinetic energy into thermal energy and sound waves in order to slow and stop a bicycle's forward motion. There are multiple kinds of bike brakes that all apply friction to a breaking surface to regulate the speed of the bike. The types of bike brakes are: Mechanical Disc Brakes, Hydraulic Disc Brakes, Caliper Rim Brakes, V-Brakes, Cantilever Rim Brakes and Coaster Brakes. In many cases, better brakes allow a rider to go faster. This may seem counter-intuative, but if we consider if a rider has more powerful and better functioning brakes, the rider will be able to maintain speed for a greater length of time going into a corner before applying the brakes.

A bunny hop is a trick in which the rider gets both wheels off the ground at the same time without the use of a jump.

Cadence is the reveloutions per minute of a riders pedalling. It is an important data point to measure for a lot of cyclists that race.

The cluster of gears (cogs) that drives the rear wheel forward. Cassettes slide onto a spline pattern that is attached to the rear wheel. Cassettes are superior to freewheels due to the fact they contain no moving parts, are lighter, and allow hub manufacturers to place the bearings further apart from each other thus strengthening the hub.

Century is a term that it used for a 100 mile bike ride.

A bearing that is built with rolling elements made of ceramic instead of steel. Ceramic is much harder than steel and can be manufactured to much more exacting tolerances of roundness compared with steel. This results in extreme low friction in the bearing, which means more of your power from the pedals gets transferred into forward motion. Ceramic bearings are the best of the best and likely the most efficient upgrade you can make on your bicycle.

The bicycle chain is the only chain that is a symbol of freedom, rather than oppression.

Bicycle chains are the main component in the transmission of power from the input gears to the output gears. A clean chain is a fast chain. Keep your chain clean and lubed and you may enjoy thousands of miles from a single chain.

When the bicycles chain it hitting bike bikes chainstays in a slapping motion caused by riding over uneven terrain.

Chainrings attach to the crank and drive power to the output gears attached to the rear wheel via the chain. Chainrings are either 1 by, single speed, or multi speed.

Also known as a Crit. A race that requires multiple laps on a short course.

A common issue. When shifted to the big front chainrin and biggest rear cog, or smallest and smallest. This stretches the chain diagonally and is usually accompanied by a noise. The solution is to shift to a different combination of gears. If you find yourself cross chaining frequently, you may want to consider upgrading your gearing.

A Specialized Innovation.

The part of the bike that holds the front wheel. Forks can be rigid or feature suspension.

A rear hub that allows the bike (primarily BMX) to roll backwards without needing to pedal.

Controlled by the Front Shifter. The Front Derailleur moves the chain from one chainring to another. The slack in the chain is then taken up by the rear derailleur. Front Derailleurs either come in 'Double' or 'Triple' depending on how many chainrings the bicycle has.

A bike that features both front and rear suspension.

A Specialized Innovation. Future shock features up to 20mm of travel to create a smoother and faster ride. Future Shock is available on some Specialized bike models. The Future Shock is positioned above the head tube in order to move in a vertical path. So when the front wheel encounters rough terrain, the bike moves up towards your hands and preserves your forward momentum without slowing you down.

The space between two jumps that a rider can jump over; take off of the first jump, and land on the backside of the second jump. A gap is also the space between two riders.

An acronym for 'Mountain Bike'.

BMC's MTT comes in two forms, MTT Stays, built into the seatstays, and MTT Suspension Fork, built into the crown of the fork. MTT Stays are found on all URS gravel bikes while MTT Suspension Forks are found on URS LT models. MTT Stays offers 10mm of rear compliance for added power transfer and control on rough terrain in a lightweight package. MTT Suspension Fork offers 20mm of travel to the fork of the bike with a spring curve optimized for gravel riding. There is a lock out on the top of the stem. BMC claims this dampens more than 46% of the typical impacts experienced during gravel riding. Bikes with MTT Suspension Forks come with three options for both spring stiffness and preload plugs, so it can be fine-tuned for each rider.

The principal about how many bikes someone should own. N being the current amount +1 being the amount needed. Therefore everyone always needs one more bike.
