The Best Mountain Bike Handlebars

The handlebar is an essential and often overlooked mountain bike component. Mountain bike handlebars are a key connection to the bike and finding the right one can reduce hand fatigue, improve your bike fit and handling. When choosing a handlebar you need to consider, rise, width, clamp diameter, and material. Here’s our primer on what to look for as well as our picks for the best mountain bike handlebars currently on the market.

Flat or Riser Bar?

When you start the search for mountain bike handlebars the first thing you’ll want to know is whether you’re looking for a flat or riser bar

Riser bars will put you in a more upright position, while lower bars will offer performance benefits like more weight on the front wheel. Traditional XC bike geometry was more focused on efficiency and aerodynamics while modern trail bikes are designed around an array of other characteristics that can benefit from personal adjustments.

Mountain Bike Handlebars

Advantages of a flat or low MTB handlebar

+ Ability to get more weight on the front wheel for more precise cornering

+ More tuned into front wheel movement
+ Less understeer in corners

Drawbacks of a low MTB handlebar

Possibly too much weight over front end
  More weight on hands, wrist, upper body

Riser bars are a great choice if you have any type of wrist or hand issues or if you notice you feel too hunched over on your bike. Not only will a more upright position alleviate aches and pains in your body, but they also have the potential to provide improved handling in certain situations —a more upright posture will be better when the trails get steeper and more technical.

Advantages of a tall MTB handlebar

+ More control on steeper trails
+ Improved sight down the trail
+ More comfortable position—less weight on hands, wrists

Drawbacks of a higher MTB bar height

Must be conscious to push front end down, especially on longer, modern bikes
Slower steering feel

Handlebar Width

Bontrager Line Pro Handlebar and Stem

Handy cut line marks on either side of the bar allows custom width.

Wider is not always better and defining the width of your bars may take a bit of trial and error as bars have gotten wider. My personal preference for bars trends toward the wider side, but a great rule of thumb is to run bars similar to where your hands rest when in a push-up stance. I recommend giving a wider bar a try first and incrementally trim off a few millimeters at a time. Cutting bars is an easy DIY project, just make sure you have a fresh hacksaw blade and a saw guide.

31.8mm vs. 35mm

There’s no consensus on which handlebar diameter is better. Thankfully, there are plenty of options in both 31.8mm and 35mm.

Over the last few years, we’ve seen more and more 35mm clamp diameter handlebars and stems after what seemed to be a solid consensus of a 31.8mm bar diameter standard. Manufacturers argue that the 35mm clamp diameter bar/stem combo can “potentially” increase overall stiffness and durability. But what many argue is that a bar with more compliance provides a more stable and comfortable interface, this can be experienced firsthand with unique bars like the titanium Black Sheep Mountain Mustache bar. But in the modern MTB industry, the idea with 35mm diameter bars is that, when done correctly, they can be lighter than their 31.8mm counterpart while still maintaining a similar strength but this lacks consideration of the bar’s compliance. In the end, there has yet to be much of a consensus as to which diameter is better, but when buying new bars make sure you have a stem with the same diameter clamp.

Carbon vs. Alloy Handlebars

Carbon Handlebar Pros:

+ Damping – Due to the unique properties of carbon, carbon bars can offer more damping performance than most alloy bars, due to the ability to lay up carbon to offer specific rider characteristics. So instead of feeling each and every vibration from the trail, carbon handlebars help to absorb some of the chatter. When you are out on a long ride, that might make the difference in more comfort for your hands.

+ Weight – One of the most obvious benefits of carbon handlebars is just how lightweight they can be. Carbon bars can be constructed to be just as strong as aluminum bars and weigh significantly less. If weight is a major concern for your bar purchase, seek out carbon.

Carbon Handlebar Cons:

– Durability – Another perceived negative to carbon bars is that they are not as durable. Scratches and cuts in the carbon can diminish the structural integrity of a bar. Where an aluminum bar might bend (which usually leads to a crack), a carbon handlebar will likely break more catastrophically.

– Cost – One main drawback of carbon bars is that they are more expensive on average, sometimes twice as expensive as some similar aluminum bars. Similar to other components, carbon is just more expensive to produce.

Aluminum Handlebar Pros:

+ Durability – One of the biggest perceived advantages of aluminum handlebars is the extra durability they offer. If you were to crash your bike, aluminum is less susceptible to scratches than carbon.

+ Cost – While carbon handlebars are often expensive, aluminum bars can be had for as little as $40. There are some examples where you could buy two sets of alloy handlebars for the cost of one carbon bar, but is two better than one?

Aluminum Handlebar Cons:

– Weight – Aluminum handlebars are most of the time heavier than carbon and so if weight is the most important thing, you might not want to go with aluminum. With that in mind, there are still some very lightweight aluminum handlebars out there.

– Stiffness – This isn’t necessarily the case for all aluminum bars. But in my experience, aluminum bars ride much harsher than similar carbon bars. Especially with the 35mm diameter, some handlebars end up being much too stiff no matter the material they use.

So what do we recommend when it’s time to replace your bike’s handlebars?

The Best Carbon Mountain Bike Handlebars

One Up Carbon Handlebar

Mountain Bike Handlebars

One Up claims “that most carbon bar designs on the market copy the tapered profile of an Aluminum bar while with carbon you can take advantage of more complex shapes to get a better performing product.” The One Up bar profile minimizes the length of the 35 diameter clamping area as this is the stiffest portion of any 35 diameter bar. By tapering the clamp diameter quickly and manipulating the bar shape to a flattened, oval shape in the transition zone and then to a standard 22.2mm clamp diameter for the control zone, the One Up bar offers amazing compliance with stiffness right where you need it. One up benchmarked their carbon bar against the most popular carbon bars on the market as well as foam-filled aluminum bars in a compliance test and they claim their results were, on average, a 21% increase in vertical compliance (comfort) coupled with a 28% increase in steering stiffness (responsiveness). If you’re looking for the most compliant 35mm carbon bar on the market, this may be it.

Widths: 800mm | Clamp diameter: 35mm |Rise: 20mm Rise (220g) 35mm Rise (225g) |Material: Carbon

Pros:

  • Great compliance for a usually stiff carbon bar
  • Reasonably priced for a well-designed carbon bar
  • All-day comfort

Cons:

  • None. This is the best 35mm bar we’ve ridden.

ENVE M6 Mountain Carbon Handlebar

Mountain Bike Handlebars

ENVE manufactures a range of carbon bars, each tuned with a specific carbon layup for each unique riding application; from the XC-oriented M5 up to a bomber DH ready M9. The trail focused M6 falls right in the middle of the range and is aimed at trail riding. Designed around a 31.8mm clamp, the bars offer a 780mm width and feature cut guidelines down to 740mm though ENVE doesn’t recommend going narrower than the 740mm as they say it will make the bars overly stiff.  The M6 bar is available as a traditional 25.5m rise or low 7.5mm rise the bars sweep 9-degrees back and 5-degrees up. If these are in your budget, they are my personal favorite MTB bars.

The Best Aluminum Mountain Bike Handlebars

Renthal FatBar V2

Mountain Bike Handlebars

Renthal went back to the drawing board to redesign their legendary FatBar to better serve all-mountain, enduro, and gravity disciplines, result is the re-engineered FatBar V2, which builds on the iconic performance and success of the first version by adding 20mm for an 800-millimeter width while reducing weight through careful application of light, yet strong 7050 T6 aluminum alloy. While adding 20 millimeters of width for better control, Renthal was able to cut weight by approximately 45 grams, which is pretty significant in a handlebar while also considering it’s still made of alloy and doesn’t cost any more than the original bar. If the Fatbar is a bit too wide for your tastes, you can always cut down the bar ends using the width markers to help you get the job done cleanly and confidently. Additionally, Renthal now offers the FatBar V2 in a stealthy black colorway. Weight comes in at 345g.

Widths: 800mm | Clamp diameter: 31.8mm |Rise: 10-40mm |Material: Carbon

Pros:

  • Clean and simple
  • Less than $100

    Honestly I think the industry started using 35mm diameter stem and bars just to change standards and add sales. The 31.8 stuff may not look as massive and cool but the work great and aren’t overly stiff.

  • Steven Weston says:

    Did you guys not look at the Spank 777 BearClaw handle bar ? Best damn bar I have ever used. 🙂

  • JtotheC says:

    While I get that most companies focus on similar sweep measurements between 8-10*, there are some noteworthy exceptions. Seems like a significant omission.

  • GH says:

    Pretty sure Enve bars are not US-made. It’d be sweet if they were, just to have that option, but AFAIK, they’re made in Taiwan just like all the rest.
