How are bicycle handlebars measured?

How do I know what size handlebars for my road bike?

The rule of thumb when selecting the correct handlebar width is to

measure the distance between the two bony bits on your shoulders

– in more scientific terms the distance between your two acromioclavicular (AC) joints. This measurement gives you a baseline – if it’s 38cm, look for 38cm bars – and so on.

What is standard handlebar diameter?

The standard handlebar diameter is

31.8 mm

. But a couple of years ago mountain bikes and road bars used different clamp sizes which were 25.4 and 26.0 respectively. Now new bikes are fitted with the standard 31.8 mm. It is always worth double-checking the size.

How do I measure my mountain bike handlebars?

The easiest way to measure this is by

using the *push-up position method

. Stem length also comes into play; typically, the longer your stem, the narrower you may want your bar width. This helps your body stay centered over the bike. If you’re running a stem that is 50 mm or less I’d suggest a 760 mm to 800 mm bar.

What is the standard diameter of bicycle handlebars?

There are only two current standard sizes: Flat bars have a

22.2 mm (7/8′′) grip area diameter. Road (“drop”) bars have a 23.8 mm (15/16′′) grip area diameter

.

Are all bike handlebars the same diameter?

How do you measure shoulders for road bike handlebars?

The most traditional and easiest way to determine the correct width is to hold the bar up to your shoulders with the ends touching the body. The ends of the bar should reach to the outside of the shoulder, but not be so wide that the ends go past the shoulder.

What handlebar width do pros use?

Other pros also use relatively narrow bars:

40 and 42 cm

are the norm.

Do all handlebars fit all stems?


Stems are available to fit a range of steerer tube sizes with 1 1/8” being by far the most common

(a shim can be use to make these fit older bikes with 1” steerers) A range of clamp sizes is available to fit the different handlebar diameters – 26/25.8mm are the traditional standard road sizes, but in recent years these …

How do I know my bike grip size?

Start by

measuring the distance from the tip of your middle finger—which is the tallest finger on your hand— to where the palm of your hand meets your wrist

. This will ensure that your grasp on the bike handle comfortably encloses the entire outer diameter of the grip.

What diameter are motorcycle handlebars?

As far as industry standards, Handlebars typically come in either

1′′ or 7/8′′

diameter. Almost all Harley applications will use 1′′, however, for those riders looking for fatter bars 1 1/4′′ and 1 1/2′′ are available and may require special clamps/hand controls depending on the bars.

Are all mountain bike handlebars the same diameter?

Mountain bike bars generally had 1” (25.4mm) clamp diameter and 7/8” (22.2mm) grip sections.

Those two grip diameters remain unchanged, even though the clamp diameter is pretty universal now at 1-1/4” (31.8mm) between road and MTB bars

.

What handlebar width Do I need MTB?

Handlebar width should purely depend on the size of the rider and more importantly the width of their shoulders. The most common mountain bike handlebar widths range from around
