A steep descent or a tight singletrack turn puts real pressure on your steering, and a bar that is too narrow or too low can make every rough section feel harder. Clamp diameter is the measurement at the centre where the stem grips the bar, and it must match the stem exactly. You also need to match rise height to your riding posture. Rise is the upward lift of the bar above the clamp, and it changes how upright your shoulders and wrists sit.

More Details On Our Top Picks
A 30mm riser in 6061 aluminium gives a straightforward upgrade for riders who want more leverage without a tall stack. The 720mm width suits tight woods, while the 780mm version adds stability on faster descents. You can trim the ends to fine tune width for a gate or doorway at home.
Back sweep is the rearward angle of the grips, listed here at 9 degrees, and it brings the hands closer to the body. That angle helps on longer climbs where wrist position matters. Check the 31.8mm clamp against the stem before ordering, since a mismatch stops installation entirely.
Where It Helps
- 330g at 720mm keeps front-end weight low
- Two widths cover narrow trails and open descents
- Hard anodising suits regular trail use
- Standard 22.2mm ends fit common grips
Things To Consider
- Grips and stem are not included in the package
- 30mm rise may feel low for very upright setups
Width is the main story here, with a full 780mm span aimed at all-mountain and enduro riding. Wider bars give more leverage over the front wheel on loose corners, and the 35mm rise lifts the grips for a less stretched position. Riders moving from a narrow cockpit will notice the change quickly.
Cut marks along both sides let the bar be trimmed in stages down toward 680mm. A centre setup grid helps keep the stem centred during fitting. In our view, that marking system makes a wide bar more practical for mixed trail use.
The Good Stuff
- 340g at 35mm rise keeps a wide bar light
- Double-butted 6061 aluminium construction
- Trim marks support staged width adjustment
- 35mm rise suits aggressive trail positions
- Hard anodised finish for trail durability
Worth Noting
- 780mm width needs checking for tight storage
Rise choice sets this one apart, with options running from 35mm up to 120mm in the range. A taller bar can bring the grips closer to a natural shoulder height on long rides. You get a 9 degree back sweep that angles the hands inward, unlike the 5 degree angles on the FIFTY-FIFTY bar.
At 780mm wide, the bar suits downhill and enduro bikes where leverage matters. The 6061 aluminium build and precision bending aim for a stiff, responsive feel. Confirm the stem clamp size first, since the listing stresses a 31.8mm match.
Notable Upsides
- Wide range of rise heights in the range
- 9 degree back sweep for wrist position
- 780mm width for downhill control
Trade Offs
- High rise versions change steering geometry more
- Wide width may need trimming for tight trails
- Stem diameter must be checked before ordering
Who It Suits Best
Riders who want a taller cockpit and a more swept grip angle on long trail days.
Where Another Pick Suits Better
The BUCKLOS 31.8mm MTB Handlebar 720mm 50mm Rise suits riders who prefer a narrower 720mm width.
A 50mm rise at 720mm width gives a middle ground between the low Wake bar and the very tall options later in this list. That height lifts the grips enough for an upright trail position without pushing the front end too high. Cut marks on both sides help with trimming after a test ride.
The 6061 aluminium construction uses hard anodising and CNC bending, where CNC means computer-controlled shaping for consistent curves. At 299.4g for the 720mm version, weight stays low. One thing worth considering is checking the exact rise variant selected, since the range spans many heights.
The Upside
- 50mm rise for a more upright position
- Cut marks make width trimming simpler
- 299.4g weight at 720mm width
- Hard anodised 6061 aluminium build
Minor Gripes
- Many rise options make selection more involved
- 720mm width may feel narrow for downhill use
Most options here use a 31.8mm clamp, so a 25.4mm clamp fills a different niche. That smaller diameter fits older stems and some dirt bikes where the wider standard will not work. Width is a narrower 620mm, which helps in tight trees and storage spaces.
A 30mm rise pairs with 12 degrees of rearward sweep, more than the 9 degrees on the Wake and PLATT bars. The extra sweep brings the grips back toward the rider for long-distance comfort. You should measure the existing clamp carefully, since 25.4mm and 31.8mm parts are not interchangeable.
Everyday Wins
- 25.4mm clamp fits older stem setups
- 620mm width suits tight trails
- 12 degree sweep for long rides
Room For Improvement
- Narrow width gives less downhill leverage
A 120mm rise is tall by any standard, and that height suits riders who want a very upright posture. Combined with 780mm width, the bar gives leverage while keeping the grips high. Long-distance riders often prefer this kind of position for back and shoulder comfort.
The 12 degree rearward sweep matches the narrower GEWAGE bar, pulling the hands back further than most rivals here. In most cases, a rise this tall works best on bikes with a low front end. A tall rise can also lift the front wheel feel on steep climbs, so geometry matters.
Useful Touches
- 120mm rise for very upright positions
- 780mm width for steering leverage
- 12 degree sweep for hand position
- 6061 aluminium construction
- 31.8mm clamp for modern stems
Points To Note
- Very tall rise suits only certain frame geometries
- Wide bar needs storage space checks
Made For
Riders with a low cockpit who want the tallest rise in this group.
Consider Something Else When
The Wake 31.8mm MTB Riser Handlebar 720mm (Black) suits riders who prefer a lower 30mm rise.
Carbon fibre changes the trade-off completely compared with the aluminium bars above. The 3K weave, a criss-cross carbon pattern, gives a stiff yet light structure for weight-conscious builds. Widths from 680mm to 760mm let riders match the bar to trail tightness.
A flat profile supports an upright position and keeps the view ahead clear on gravel and bumpy roads. The 31.8mm clamp must match the stem, same as the aluminium options. For most riders, the appeal is lower weight at the front of the bike.
Why It Works Well
- Carbon fibre build for low front weight
- Multiple widths from 680mm to 760mm
- Flat profile for upright riding
- Matte and glossy finish options
Softer Spots
- Carbon needs careful torque during fitting
- Flat profile gives less rise than riser bars
- Stem diameter must be confirmed first
What Matters Most Before Choosing Mountain Bike Bars
Clamp Diameter First
Measure the stem clamp before anything else, since 25.4mm and 31.8mm bars cannot be swapped. A mismatch blocks fitting and forces a return. That single check narrows the list faster than any other detail.
Width For Control And Clearance
Wider bars give more leverage on descents and loose corners, while narrower bars slip through tight trees and storage spaces. Riders in dense woods often prefer 620mm to 720mm, while open terrain suits 760mm to 780mm. Your local trails should drive the choice.
Rise And Sweep For Posture
Higher rise lifts the grips and can ease shoulder strain on long rides, while more back sweep brings the hands closer to the body. Low rise suits aggressive positions, and tall rise suits upright touring setups. You should match both numbers to the frame geometry, not just comfort preference.
Material And Weight
Aluminium bars in 6061 alloy keep costs sensible and handle trail impacts well. Carbon bars cut front weight but demand careful fitting and torque care. Weight matters most on long climbs, while stiffness matters most on rough descents.
Key Considerations Across These Picks
Common Shopping Slip Ups
Ordering by width alone causes many mismatches, since clamp size and rise get overlooked. Trimming a bar before riding it also removes the chance to test a wider setup. Measure the stem, then check storage clearance for wide bars.
What The Higher Tier Buys
Higher tier bars use carbon fibre to cut weight and change ride feel at the front end. The gain shows up on long climbs and weight-sensitive builds. Aluminium remains sensible for riders who prioritise simple fitting and trail toughness.
Frequently Asked Questions
What clamp size do most modern mountain bikes use?
Most modern stems use a 31.8mm clamp diameter. Older stems and some dirt bikes use 25.4mm instead.
How wide should a mountain bike bar be?
Widths from 720mm to 780mm suit most trail riders. Tighter trails may suit 620mm to 700mm.
What does rise height change on a bar?
Rise height lifts the grips above the stem clamp. Higher rise creates a more upright riding position.
Can a wide bar be cut down to size?
Many aluminium bars include cut marks for staged trimming. Trimming should be done evenly on both sides.
Is carbon better than aluminium for handlebars?
Carbon is lighter and stiffer, while aluminium is simpler to fit and maintain. The right choice depends on weight goals and riding style.
Closing Remarks
Match clamp size first, then width, then rise, and the right bar becomes clearer. Riders who want a tall upright setup should look at the 120mm option, while most trail riders will focus on 720mm to 780mm aluminium bars. Carbon suits weight-focused builds, and aluminium suits straightforward trail use.
