MTB Handlebar Buyers Guide (Everything You Need to Know!)

In this MTB Handlebar Buyers Guide, we are going to breakdown everything you should consider before buying a new set of handlebars for your mountain bike. The handlebars are arguably the most important contact point on your bike. With so many different handlebars available from a variety of different brands, mounting up two different handlebars on the same bike can drastically change your experience on the trail. We are here to unpack some of the details that play in to those different handlebars so you can find the right set of bars for your bike!

Materials 

When it comes to handlebars, typically they are made from either alloy, carbon, or titanium. With mountain bikes in particular, typically you will find handlebars made from either alloy or carbon. Keep in mind that all manufacturers have their own approach, but in general, carbon handlebars have different damping characteristics than aluminum, the flex pattern designed in to the bars can be more methodically placed, they are more lightweight, but they cost more to manufacture, and they are usually less durable to nicks and scrapes than aluminum. On the contrary, aluminum handlebars are extremely durable, if they do fail, it's not typically a catastrophic failure, they won't hurt your back pocket quite as much as carbon, but can sometimes be overbuilt and too stiff with a 35mm clamp diameter.  Each of the different materials have their strengths and weaknesses and their pros and cons. For more information on comparing different materials used for mountain bike handlebars, check out our recent article Carbon vs Aluminum - Which Bars Should You Ride?

Handlebar Rise and Sweep

The handlebar rise and sweep are what define the shape of your handlebars. There is a sea of different handlebar options with way too many different rise and sweep configurations to count. For starters, the rise of the handlebars is the vertical rise measured from the center of the bar to the bar end. Some different mountain bike handlebars will range from a 0mm rise to around a 40mm rise. The more handlebar rise, the taller the handlebar will feel. If you are someone constantly riding extremely steep terrain, you might benefit from a handlebar with a higher rise. What that higher rise does is it allows you get more of your weight over the back of the bike, something that is crucial when the trail gets steep. On the other side of the spectrum, if you are riding a pure bred XC bike, having a lower rise bar will hep keep weight over the front of the bike on those steep climbs. 

On the other hand, sweep is effectively the bend of the handlebar and is broken down between up sweep and back sweep. Check out the two illustrations below of a front view and a top view to help understand the difference between up sweep and back sweep. Up sweep, which can be seen from the front view, is the angle measured from an imaginary line drawn parallel to the clamping surface and perpendicular to the direction of rise up to the handlebar. Back sweep, which can be seen from the top down view, is the angle measured from an imaginary line drawn from the clamping surface back to the handlebar.  Typically the up sweep for a mountain bike handlebar is about 5°. The back sweep for mountain bike handlebars usually ranges from 7° to 10°. The different handlebar sweeps available is very much a comfort thing. With more back sweep, naturally your upper body is in a bit different position than with a flatter bar. Finding what is comfortable for you is what's most important here.

35 vs 31.8mm Clamp Diameter

Over the last couple of years, we have seen the industry pushing more 35mm clamp diameter handlebars and stems. The two different standards certainly have tradeoffs. 35mm clamp diameter handlebars and stems can potentially increase overall stiffness and durabilityKeep in mind that more stiffness isn't always the right answer! Having a handlebar and stem combination that is also compliant to the vibration of the trail is important. The 35mm diameter handlebars, when done correctly, can actually be lighter than their 31.8mm counterpart while maintaining the same strength. On the contrary, it is possible that the two handlebars could be the same weight, one being stiffer than the other. In the end there are a lot of variables that come in to new mountain bike "standards" and everyone has there own preference as to what works and what doesn't.

What Handlebars for Which Bike?

While there is no cut and dry handbook on which handlebars you should run on which bike, here are some guidelines that will hopefully steer you in the right direction. Everyone has there own bar width preference as well, but a good rule of thumb is the more aggressive the bike, the wider the handlebars should be. 

  • Cross Country Bikes: XC bikes are usually most happy when mounted with with a lower rise handlebar. The lower rise bar allows you to keep your weight over the front wheel of the bike more easily on steep and technical climbs. A lower rise bar in combination with a longer stem will help you put out good power when you hit those big climbs. Most all handlebars on XC bikes are made from carbon fiber, because having a lightweight setup is crucial. 
  • Trail/Enduro Bikes: On trail/enduro bikes, you will find a large variety of different handlebar setups. If you are spending long days in the saddle, having a carbon handlebar that absorbs vibrations well will certainly keep your hands feeling more fresh. Your preferred rise and sweep is what is most important, and anywhere from 10mm to 35mm rise could suit your trail or enduro bike nicely. 
  • Downhill Bikes: On downhill bikes, you will generally find the highest rise bars, that way it is easier to get your weight back over the rear wheel when descending on steep terrain. You could go back and fourth between either carbon or aluminum handlebars here, but at the end of the day, the downhill bike is the bike that sees the most abuse. A set of aluminum handlebars are generally a bit more durable than the same carbon offering and won't hurt your back pocket as much either.

1. OneUp Components Carbon Handlebar

MTB Handlebar Buying Guide - Worldwide Cyclery

The goal for the new OneUp Carbon Handlebars was to make the best feeling bar possible, something which would let you ride harder for longer. The solution is OneUp's patent pending oval shape which combines the best ride characteristics of 31.8mm and 35mm bar standards into one package. This is the most comfortable bar we’ve ever ridden, period. It's strong, lightweight, minimizes arm pump and vibration, and maximizes steering response. 35 done right.

The OneUp bar profile minimizes the length of the 35 diameter clamping area as this is the stiffest portion of any 35 diameter bar. The 35mm clamp diameter quickly changes to a flattened, oval shape in the transition zone and then to a standard 22.2mm clamp diameter towards the bar ends.
