A wider bar changes steering leverage on loose descents and tight switchbacks. Rise lifts the grips toward your torso, which alters comfort and front-end feel in a way stem length alone cannot. Clamp diameter, the measurement where the bar meets the stem, must match the stem exactly, so checking that number before anything else prevents a wasted purchase.

A Deeper Look At The Lineup
The Wake 31.8mm MTB Handlebar 720mm Black suits riders who want a straightforward riser bar without extra complexity. A 30mm rise and 9 degree backsweep, meaning the grips angle back toward the rider, keep hands in a natural line on longer trail days. That geometry matters more than raw weight for comfort on rough descents.
At 330g in 720mm length, the 6061 aluminum construction stays light while the matte black finish resists scuffs from gloves and straps. You match the 31.8mm clamp to the stem, then transfer brakes, shifters, and grips, since those parts are not included. In our view, that simple setup suits downhill and off-road use where control matters most.
Practical Advantages
- 6061 aluminum keeps weight low at 330g
- 30mm rise supports a relaxed riding position
- 720mm width gives leverage without feeling unwieldy
- Matte surface reduces glare during bright rides
Things To Consider
- Stem must share the 31.8mm clamp size
- Grips and stem are not included in the package
The FIFTY-FIFTY MTB Riser Handlebar 780mm leans toward riders who prefer a wide stance for all-mountain riding. Its 35mm rise raises the cockpit, which can ease shoulder strain on technical terrain. Compared with the Wake bar above, the extra 60mm of width adds leverage, though tight trees demand more care.
Double-butted tubing, a construction method that varies wall thickness along the bar, keeps the 340g weight down while hard anodizing adds surface protection. Cut marks on both sides let the width be trimmed to 680mm, 700mm, 720mm, 740mm, or 760mm. Your stem needs a 31.8mm clamp, and trimming is permanent, so measuring first matters.
Benefits That Matter
- 780mm width improves steering control on descents
- Cut marks allow precise width adjustment before trimming
- 35mm rise creates a more comfortable upright posture
- 6061 aluminum with hard anodizing resists wear
- Central setup grid helps center controls accurately
Worth Noting
- 780mm width can catch on narrow trail obstacles
- Trimming the bar cannot be reversed
- 31.8mm clamp compatibility must be confirmed
Who It Suits Best
All-mountain riders who want width and adjustability for enduro-style trails.
Where Another Pick Suits Better
PLATT 31.8mm MTB Handlebar 780mm 35mm Rise suits riders who want more rise choices up to 120mm.
The PLATT 31.8mm MTB Handlebar 780mm 35mm Rise stands out for the number of rise options available, from 35mm up to 120mm in the listed range. That flexibility helps riders fine-tune cockpit height without changing the stem. You’ll notice the difference most on long climbs, where a higher bar can reduce back strain.
Unlike the FIFTY-FIFTY bar, this design uses a 9 degree backsweep to place shoulders in a neutral position. The 6061 aluminum build uses precision bending for smooth curves, and the 22.2mm bar ends fit standard grips. For most riders, matching rise to torso length matters more than chasing the tallest option.
The Upside
- Multiple rise heights support different riding positions
- 9 degree backsweep helps reduce wrist fatigue
- 780mm width aids control on rough terrain
Trade Offs
- Higher rises change handling and require control checks
- Stem clamp must match 31.8mm before ordering
The Wake Bike Handlebar 31.8mm 720mm 55mm Rise adds color and a taller rise to the basic riser formula. Sandblasted finishes in five colors, including purple in this version, let the cockpit match the frame. That visual choice pairs with a 55mm rise for riders who want a more upright stance.
Compared with the first Wake bar, this version offers 30mm or 55mm rise, a 5 degree upsweep, and a 6 degree backsweep. The 6061-T6 aluminum tube uses varied wall thickness to absorb vibration, and weight sits around 310 to 350g depending on length. You want the 720mm length for tighter trails, while 780mm suits open, fast terrain.
Reasons It Performs
- 55mm rise option supports upright comfort
- Color range allows visual customization
- Varied wall thickness helps absorb road vibration
- Lightweight build aids handling and maneuverability
Minor Gripes
- Extreme vibration use is not recommended by the maker
The BUCKLOS 31.8mm MTB Handlebar 720mm 50mm Rise focuses on flexibility across bike types, including folding bikes and e-bikes. Its 50mm rise sits between low and high options, which can suit your riding position without a stem swap. Cut marks on both sides make width trimming straightforward during setup.
Hard anodizing and precision bending shape the 6061 aluminum tube, and the 720mm version weighs about 299.4g. Unlike the Wake 55mm bar, this model emphasizes width adjustment over color choice. One thing worth considering is rise range, since listed options extend to 160mm, so confirming the exact variant matters.
Noteworthy Benefits
- Cut marks simplify width adjustment on both sides
- 50mm rise balances comfort and control
- Compatibility extends to MTB, folding, and e-bike frames
Room For Improvement
- Exact rise and width variant must be selected carefully
- 31.8mm clamp needs to match the stem
- Trimming width is a one-time decision
Made For
Riders adapting a mountain bike, folding bike, or e-bike cockpit with a mid-height rise.
Consider Something Else When
Funn Upturn Handlebar 35mm 800mm 75mm Rise suits riders who need a 35mm clamp and 800mm width.
The Funn Upturn Handlebar 35mm 800mm 75mm Rise breaks from the 31.8mm pattern with a 35mm clamp and 800mm width. That wider, taller setup targets BMX and aggressive trail riding, where an upright position improves visibility. You need a matching 35mm stem, so measuring the current clamp is essential before ordering.
AL6061 aluminum keeps the bar light, and indication marks help place shifters and brake levers consistently. Rise options include 40mm, 55mm, and 75mm, giving a clear path to a more upright cockpit. Compared with the PLATT bar, the Upturn trades rise variety for width and a larger clamp standard.
Positive Points
- 800mm width provides strong steering leverage
- 75mm rise supports an upright, visible position
- Indication marks simplify control placement
- AL6061 construction balances weight and strength
- Suits BMX and aggressive trail use
Points To Note
- 35mm clamp excludes standard 31.8mm stems
- 800mm width may feel wide in tight trails
The 31.8 Bike Handlebar 780mm 25mm Rise keeps geometry low while retaining a wide stance. A 25mm rise suits riders who prefer a more aggressive, forward position than the high-rise options above. Its 12 degree rearward sweep, the largest sweep in this lineup, angles the grips back more to ease wrist strain.
6061 aluminum construction aims for stiffness and responsiveness on rough trails, with a design meant to absorb some chatter. Your wrists benefit from that sweep on long-distance rides, though riders wanting a tall cockpit will look elsewhere. Installation follows the same pattern as the other 31.8mm bars, with controls moved over after fitting.
What Stands Out
- 780mm width supports confident steering
- 12 degree sweep promotes a neutral wrist position
- 25mm rise suits a lower, aggressive cockpit
- 6061 aluminum keeps the build responsive
Softer Spots
- Low rise offers less upright comfort than high-rise picks
What Matters Most Before Choosing Mtb Handlebars
Clamp Diameter And Stem Fit
Clamp diameter determines whether the bar fits the stem at all. Most picks here use 31.8mm, while the Funn Upturn uses 35mm, so checking the stem marking saves a return. You should also confirm bar-end diameter, commonly 22.2mm, before moving grips over.
Width, Rise, And Sweep
Width affects steering leverage, rise changes torso angle, and backsweep shifts wrist position. A 780mm bar feels different from 720mm on singletrack, and a 75mm rise feels different from 25mm on climbs. Matching those three numbers to trail type matters more than finish or color.
Material And Adjustment Marks
6061 aluminum appears across the lineup, with hard anodizing and precision bending as common treatments. Cut marks on the FIFTY-FIFTY and BUCKLOS bars allow width trimming, which is useful but permanent. Measuring shoulder width and current bar width gives a practical starting point for trimming.
Key Considerations Across These Picks
Common Shopping Slip Ups
Ordering by rise alone, without checking clamp size, creates the most frequent mismatch. Trimming a wide bar before measuring the trail clearance can also limit future adjustment. Confirming both numbers first keeps the swap simple.
What The Higher Tier Buys
Higher-priced options in this category often add rise choices, larger clamp standards, or wider widths for specific disciplines. Those differences pay off for BMX or aggressive trail riders who need an 800mm, high-rise setup. For standard trail use, a mid-range 31.8mm bar covers the core needs.
Frequently Asked Questions
What clamp size do most mountain bike handlebars use?
Most options in this lineup use a 31.8mm clamp diameter. The Funn Upturn is the exception, using a 35mm clamp that requires a matching stem.
How does rise affect riding position?
Rise raises the grips above the stem, which brings the torso more upright. Higher rises, such as 75mm, suit riders seeking visibility and comfort on technical terrain.
Can a 780mm handlebar be cut down?
Some bars, including the FIFTY-FIFTY and BUCKLOS models, include cut marks for trimming. Marks list widths such as 680mm, 700mm, and 720mm, and trimming cannot be undone.
What does backsweep do?
Backsweep angles the grips backward toward the rider. A 12 degree sweep, as on the 25mm rise bar, places wrists in a more neutral line during long rides.
Are grips and stems included with these bars?
Bar-only packages typically exclude grips and stems. Controls, grips, and bar plugs need to be transferred from the current setup or sourced separately.
Final Verdict
For most trail riders, the Wake 31.8mm MTB Handlebar 720mm Black offers a simple, light starting point. Riders who want width and trimming flexibility should look at the FIFTY-FIFTY model, while high-rise needs point toward the Funn Upturn. Match clamp, width, and rise to your trails, and the choice becomes clear for your next ride.
