A bike handlebars or bike handlebars are steering controls for bicycles; it's the equivalent of a steering wheel for vehicles and boats. In addition to steering, the handlebars also often support a portion of the weight of the rider, depending on their driving position, and provide a convenient mounting point for brake lever, shift lever, cyclocomputer, bell, etc. The handlebars are attached to the bicycle rod which in turn sticks to the fork.

History

The dandy horse, or draisienne, was created by Karl von Drais and the first two-wheeled vehicles are arranged simultaneously, controlled by a bar connected to the front steering mechanism and held by the hands of the rider. The first handlebars are solid rods of steel or wood, depending on the manufacturer. Curved, shaped mustache, drop handlebars became popular in the 1880s and was created by Percy Stenton of Ardwick, Manchester. Whatton's bars were developed in an effort to improve the sen-range security. Handlebars made of wood, not of steel, were used on safety bikes to reduce weight in the 1890s. Although aluminum had been used to make bicycles as early as 1935, it was considered unsafe for the handlebars until Cinelli produced them in 1963.

Handlebar type

Tails come in a variety of types designed for certain riding types.

Drop

The typical handlebar handlebars have a straight central part attached to the rod, with each end curved forward and downward, and then back toward the rider at a lower position. This is a very popular type of handlebar, and their exact shape and purpose make them further categorized as follows.

Standard

It's a classic racing handlebars, like those used on road bikes or tracks. Blades are designed with three basic parameters; reach, drop, and width. They can be further classified into three categories. Classic typically has a long, deep and deep, Shortcut range that displays the shorter and shallower drops and the ergo/anatomy described below. Drop bars may have one or two longitudinal indentations so that brakes and wires shift are not very prominent when wrapped under adhesive tape. They may also have flat tops.

Track

Track drop bar is a variation of a bar designed for a typical track cyclist riding position. Track drops are characterized by large, sweeping ramps, effectively blocking the position of the upper hand and the brake cap, but promoting the use of the rider from the tip, or "hook". The track bar is designed to be used without brake lever, but recently experienced a surge in popularity on use with fixed gear bikes, and thus has been adjusted to fit the lever and hand position.

Ergo or anatomy

The shape of the fall may be a simple traditional curve, or it can have flat dots (straight parts) that some riders feel more comfortable for their hands. This bar can be described as ergo or anatomy .

Randonneur

Drop the slightly elevated bars from the center in the shallow U, and the dropping part of the bar is set wider than the curve at the top. Designed to be slightly more comfortable than a straight steering wheel for the bike used in Audax rides.

Drop-in

At one time, manufacturers and racers were experimenting with a drop-in bar that had an extra extension in the head tube on the back of the drop. This is intended to offer a more aerodynamic position, due to low and narrow hand placement, rather than just drops, while still remaining legal for mass races. Their popularity is decreasing. Bullhorn

Speaker (or chase ) handlebars, upward and forward curves. They are often paired with special clip-on triathlon bars when used on the road (see above), and are also popular on their own on tracks, single speed, and fixed-gear bikes.

The style of the handlebar is named after the discipline of the race track that was originally used, and has the common nickname "Speaker loudspace" for their appearance, especially when the rider's body position is fully extended to lean forward and maintain bike control..

The enhanced loudspeaker bar can be built simply by cutting off the drop off drop bar and then installing it upside down so that the initial drop drops slightly up the hook to rest the hand, although this does not provide many forward or down extensions (if desired, usually for use based on trial time) as the purpose of the loudspeaker. This is sometimes called the "Flopped and Chopped" or "Flipped and Clipped" bar, and if this is to be done, care must be taken to properly remove the sharp edges of the cuts, and to record correctly and attach the tip of the rod for safety purposes.

Bullmoose

The bullmoose style is common on an early mountain bike. The bars and rods are one unit and where the top of the single rod will be present, there are 2 bars incorporated in the quill to the back and connected to the conventional handlebar in front, at two locations outside the center, forming a triangle. This type of handlebar is usually very large, allowing for easy breath intake under pressure. However, being heavier than contemporary flats or enhancement bars and less adjustable height and distance from the riders' bodies, they are increasingly disappearing.

Flat

Flat Flat is a standard handlebar equipped with mountain bikes, hybrids, and recently on fixed-gear bikes and flat street bikes. A flat bar is a tube that is almost straight, in many cases slightly bent toward the rider. Many penny-farthings and early safety bikes have a flat handlebar. The angle between the ends of the handlebar rather swept back and the axis of the stem brace is known as the sweeping angle .

Riser

A riser is a variation of the flat blade where the outside of the blade rises from the centerline area of ​​about 15 to 50 mm. Both flat and high bars can be added with the tip of the rod, providing more hand positions.

Triathlon or aero bar

The Triathlon beam or aerobars includes a variety of aerodynamic aerodynamic styles for racing bikes and especially the test bike. Includes narrow, bolt-on extensions that pull the body forward into tucked positions, a bar chase that spreads the rider's arms but drops the body into a slightly lower position, and an integrated unit that combines elements of both designs.

Using the aero bar allows the rider to reduce the time on a trial time of 40 km per second for 90 seconds.

Triathlon bars are commonly used in triathlons and test times on roads and trajectories. However, they are illegal in most of the mass start races or other events where drafting is allowed because, while aerodynamically beneficial, they tend to pull the hands away from the brakes, making the rider slightly more unstable on the bike, and can be dangerous in the event of an accident. Furthermore, they are useless in shorter sprints or climbs where power is more important than aerodynamics.

A special lever shift (known as a bar-end shifter) does exist that can be mounted on some triathlon bars so that it can be achieved without moving the hand from the aerodynamic position. The complementary brake lever in the handlebar configuration is placed at the end of the accompanying chopsticks.

The Aero bar was a recent addition to race-time trials, with Greg LeMond first using it on the Tour de France in 1989. In a controversial time trial on the final day, LeMond used them to defeat 58-second yellow Laurent Fignon shirt , changing the 50 second deficit to 8 seconds. Fignon protested against the use of this bar but to no avail.

BMX

The BMX style handlebars , as used on BMX bicycles, have more increments than straight rods and usually have crosslinks to produce stiffness and strength.

Upright or North Street

One of the oldest types of handlebars, and perhaps the most common for city bikes, this type of bar is named after the North Road Cycling Club in London and then used on a three-speed and single-speed Raleigh, Schwinns, and three other bike rides until the 1980s, as well various European utility bikes and roadster. They are also known as "Townie", or "Tourist" bar. The North Road bars are more or less swept towards the rider; in extreme cases every grip ends almost parallel to the other and the bike frame. They recently enjoyed a revival of popularity on some of the hybrid bikes, city bikes, and comfort models. The North Road blade can be easily reversed to give an approximate ~ 4 inch number of drops when a more aggressive driving posture or a sporty look is desirable.

Porteur

Porteur bar is designed to accommodate a rack or basket mounted on the front to transport the cargo and is usually found on special Porteur bikes. The curve is usually nearly flat in the center, then sweeps backwards to the rider with different shapes, and with a slight decrease in some cases.

Cruiser

Exploters handlebars, like those used on a cruiser bike, tend to be long and tilt to the back of the bike so that the rider can sit upright.

Condorino

The condorino blade is bent slightly less than 90 Â ° forward, and then 90 Â ° out with sharp corners. No hikes and it's much narrower than the normal city bike bar. It was widespread in Italy from 1950 onwards, and was marketed to customers who wanted sporty bikes that could still be used for general purposes (going to work, etc.) In the years where racing bikes were not affordable by most people. This is increasingly losing popularity when street racing bikes became common, and in the early 1980s it was out of production.

Whatton

Whatton Circle behind the penny-farthing rider's feet so they can still keep their feet on the pedals and can also jump-first feet up from the engine. It is also used on a recumbent bike for steering under seats.

Tour or trekking

Sometimes referred to as the "Butterfly" bar, it is commonly found in continental Europe. They usually consist of a broken eight-figure arrangement that is horizontally mounted on the trunk. This bar style allows the rider to remain relatively upright while at the same time providing various hand positions for comfort on long-term travel. The Butterfly bar variety is fitted with the 'P-type' Brompton folding bike. This is different from other Butterfly bars because it's mounted vertically rather than horizontally.

Mustache

Mustache the handlebars arched forward from the rod and then back toward the rider. This style was designed in the early 90's by Grant Petersen for Bridgestone XO-1, based on the semi-drop bar used by Japanese schoolchildren.

Ape hanger

Ape hanger The handlebars rise in steep U from the base, so the rider's hand rests above the waist level. This bike's handlebar style became very popular in the 1960s after the introduction of wheelie bikes like Schwinn Sting-Ray, Raleigh Chopper, and a very stylish young bike that mimics the appearance of drag racing or chopper motorcycles today. The United States legislation introduced during the 1970s limits the factory-installed maximum handlebar height to 16 inches above the lowest seat setting; EU security rules use the same limit of 400mm. Apehanger style remained common in the US until the mid-1980s, and is still frequently seen on lowrider bikes.

Recumbent

Recumbent bikes, because of their diversity, are often equipped with handlebars that are not visible elsewhere. These include the handlebars with a very long range, similar to an ape hanger (see above) but mounted less vertically, and handlebars designed for steering under a chair, called the Whatton bar.

Design

The handlebar design is a trade-off between some desired qualities:

Design goal

The design goals of the handlebars vary depending on the purpose of bicycle use. General for all bicycles:

• Gives the necessary influence to direct the bike.
• The exact position of the rider's hands matches the purpose and style of the bike.
• Provides a mounting platform for brakes and gear levers and various accessories.

Racing/touring and triathlon bars have additional goals:

• Enable the rider to assume aerodynamic position.
• Enable the rider to change the position of the hand and body during the long journey, preventing fatigue.
• Enable aerodynamic routing of brake/gear cable.

The purpose of the mountain bike design is less focus on aerodynamics, more on the negotiation field:

• Provides sufficient control to maneuver the bike over the obstacles.
• Strong enough to withstand the extra power generated in some events/strikes.
• Optionally: do not increase vehicle weight significantly.

BMX and dirt-jump bike bars have the same needs as mountain bikes, with additional incentives to allow for smoother controls, such as special handling during bike time in the air or during certain maneuvers.

Materials

Handlebars are most often made of aluminum alloy, but are also often made of steel, carbon fiber or titanium.

Size

There are several parameter sizes to consider when choosing handlebar:

Width

Drop bars have a wide range from 34 to 50 cm (13 to 20 inches). Usually a rider will choose a bar that roughly matches the width of their shoulders so that their arms can be roughly parallel. The width is measured at the end of the drop section but the exact method varies from manufacturer to manufacturer. Several sizes from the outer edge to the outer edge (eg, Deda, ITM, TTT, Pinarello Most) while others measure from center to center (eg, Cinelli, Profile Design, Ritchey, Salsa). The number returned by measuring outside to the outside tends to be 2 cm ( ³ / ₄ at) greater than measuring center to center for the same handlebar.

Stem diameter

Care is required when choosing a handlebar to match the rod, or vice versa, because there are some standards. The ISO standard for the stamping clamping area of ​​the handlebar is 25.4 mm (1 inch), which is used on mountain bikes and many handlebar roads made in Japan. However, the unofficial Italian standard is 26.0 mm ( 1 ¹ / ₃₂ at), which is the size of the clamp most common for crossbar. There is also a medium size such as 25.8 mm ( 1 ¹ / ₆₄ on) to try to achieve compatibility with trunk ISO or Italian, and an old Cinelli-specific size of 26.4 mm ( 1 / ₆₄ at). In practice, many modern trunks with removable faceplates sufficiently accommodate small differences in the size of the handlebar clamp, but older stem types with one pinch bolt should be accurately matched. In the days of chicken feather trunks, the stem is clearly identifiable from the "7" shape, but at present it can be difficult to distinguish between "paths" (26.0 mm [ 1 ¹ / ₃₂ in]) and "MTB" (25.4 mm [1 in]) bar. Manufacturers often remove the size of the clamp from the ad or the packaging.

The new standard is a 31.8 mm (1.252 inch) or 31.7 mm (1,248 inch) "oversized" brace for MTB and a crossbar. It's popular in mountain bikes, especially those who focus on "all mountain" and "downhill" activities, because the stems and handlebars can become stiffer and lighter. This clamp diameter takes over from the previous size mix on the bike path with the drop-bar. In this stalk, standard brake levers can be used because only the middle part is too large even though other accessories installed near the rod should also be large to fit (some brackets can be adjusted). Shims available to fit 25.4 mm (1 inch) or 26 mm ( 1 ¹ / ₃₂ In bar to 31.8 mm (1.252 inches) rod, so many new rod models are just great.

In 2012 Easton's producer bar also launched a 35 mm ( 1 ³ / ₈ on) for bars and bars. It is specifically developed for high load applications such as downhilling. Easton claims a further increase in strength and stiffness while reducing weight.

The BMX style handlebug requires a clamp diameter of 22.2 mm ( ⁷ / ₈ at) and is therefore incompatible with certain non-BMX rods.

Lever clamp and grip diameter

In addition to the area of ​​the stem clamp, the shifter and/or the brake lever and the handle area on the bar may have several different diameters. For traditional road and mountain handlebars, this diameter is standard and so historically there is little confusion except when mixing road and mountain components. However, in recent years there have been cross-sectional types that do not fall into one category or other category, and can be imagined using a type shifter, brake lever or handle (for example an upright-style bar). For this reason, certain handlebars are now available in a variety of sizes related to shifter or lever brake lever diameters.

Standard standard handlebar handles (including tracks, cyclocross and touring bars) use a 23.8 mm diameter handle/lever ( ¹⁵ / ₁₆ , which only suitable for road bike or brake shifter type This diameter is usually not important to grasp because this bar is most often wrapped with ribbons.An exception is the one-piece track grip, which is sized to fit the bar diameter of 23.8 mm ( ¹⁵ / ₁₆ at) and, therefore, will not match the mountain bike handlebar). The Cyclocross brake levers are sized according to the drop bar style, and also will not match the mountain bike handlebars.

Other common lever sizes/handles are used for mountain and city handlebars, including flat blades, enhancement bars, some porteur bars, etc. In this bar the area of ​​the lever and grip has 22.2 mm ( ⁷ / ₈ Ã, in) diameter. Therefore, thumb-transfer levers, grip type sliders, MTB brake levers and Rapidfire type displacements will only fit on this smaller diameter - nothing that can fit in the road or the cyclocross bar.

Cover handlebar

Handlebars typically have masking tape or grips to provide grip and comfort. In general, the handlebars that have one driving position have a grasp, and the handlebars that give some use of the tape.

Tape

There are many types of ribbon handlebar:

• Polyurethane ribbons, introduced in recent years, provide bearings.
• Composite rubber band
• Cork tape, padded tape, provide pads but less durable.
• Bicycle ribbons, plastic tape with smooth waterproof surface.
• Benotto "Cello-Tape", made of plastic, was popular in the 1970s and 1980s. Compared to other types of ribbon handlebar it is relatively thin and not installed; it does not provide any bearing from the street vibration. However it is durable, does not absorb water, is available in various colors and is kept clean. A similar type of "glossy ribbon" exists.
• Tape cotton, cotton wool adhesive without adhesive with adhesive, similar to a twill ribbon.
• Wrap the skin, for example by Brooks England
• An inner tube can be cut and wrapped also
• Foam rubber tubes have been used on cheap bikes.

The tape can be applied in several ways, either wrapped from the tip toward the rod or starting near the stem and wrapped towards the end. The tape is usually held at the end with a rod end bar. The other end of the tape may be held with adhesive tape, usually an electrical insulating tape or, if started near the rod, by first wrapping a few turns toward the rod before reversing direction to attach it. An eight digit can be made around the brake lever clamp to completely cover the bar, or a small piece of separate tape can be placed on the back side to cover the small v-shaped section that may be left empty. Gel strip strips can optionally be applied to handebars before applying tape to reduce vibration transmission and increase comfort.

Handheld

Grips are usually made of hard or soft plastic, foam, gel, or sometimes leather, depending on expected usage or desired price. They may be just smooth and round or shaped to fit the shape of a better human hand. Foam grips can be applied by immersing them underwater and then infusing them with 200,000 Pa (30 psi) of air while massaging them onto the handlebar. A quick way to use a foam handle is to spray the end of the rod freely with a hair spray and then slide on the grip and adjust the rotation quickly; leaving them alone, the hair spray will soon fix it in position. Plastic grips can be heated in water and pressed onto the handlebar. Finally, small amounts of isopropyl (rubbing) alcohol may be applied to the surface of the stem during lifting or grip-mounting to provide lubrication, which, when allowed to dry, leaves no residue.

Plug

The handles with the open end should have a handlebar plug mounted on the open end for safety reasons. These can be made of metal, usually steel, or plastic. Without them, the tip of the bar can cause serious injury to the hard impact with soft tissue. Spark plugs are also required by competitive cycling regulators.

The bar ends

In cycling, the rod end is an extension normally placed on the end of a straight handlebars. They extend away from the handlebars and allow the rider to vary the type of grip and posture they use during the trip. They are very effective when climbing out of the saddle, as they increase the leverage. The end of the stem can also increase the comfort for the rider because of the neutral position of the hand (the palm inward) which puts a little stress on the muscles, and by providing more than one place to rest the hands in the long journey.

Some handlebars have rod ends that are welded onto it but most are clamped to the end of the bar. They are available in various shapes and sizes, such as fat models that are about 100 mm long for people who curve around so as to give the position of more hands. You can also purchase a combined ergonomic hand grip with integrated rod tips.

The bar ended up very popular on mountain bikes from the early 1990s until the late 1990s, when the upswept "puller bar" was back into fashion; combinations of riser bars and rod ends are rarely seen.

The end of the stem can prove to be difficult when negotiating the winding tracks among the trees because they can associate the branch and cause an accident. They also provide protection to the rider's hands when falling or falling. However, by moving the hands farther away from the brake lever, they can increase the time it takes to stop the bike.

The use of rod ends is prohibited by the street racing regulator. Accidents can be easily caused by hooking other riders' handlebars during tight-rising bunches and extra stem ends can cause severe injuries during rare collisions in that discipline.
