Uukha U5 Omega Review

The Omegas are the current top of the line ILF limbs by the French company, Uukha.  As an early adopter and fan of the brand since 2018,  I am very familiar with how their limbs perform and feel. 

Let’s get one thing out of the way.  Is all the hype about the Omegas real? Are they really faster, smoother and more forgiving than other limbs? YES. But, with all things archery, they are not for everyone. 

Allow me to talk about the good, the bad and let’s see who these limbs truly are for.

The Uukha Omega limbs feature the U5 profile. It is designed to maximize speed and stability by utilizing a 100% carbon construction and a specialized "screwless" design which gives it a very clean look. I just wish they still made small logo versions like my old UX100s.

Technical Specifications:

• Material 100% Monolith Carbon (High-quality carbon fabrics)

• Fitting Standard - ILF

• Profile U5 Design (Linear draw profile for smooth finish)

• Lengths 66", 68", 70", 72" (Measured with a 25" riser)

• Draw Weight 24# to 48# (Available in 2 lb increments)

• Construction Screwless design (Reduces mass and limb thickness)

I did my testing on my Barebow rig.  Gwynbleidd.  25 in Hoyt Xceed, 40 70 limbs. Island Archery Javelin carbon aluminum arrows.

Key Performance Characteristics

• Speed: These limbs are engineered to achieve equivalent arrow velocity with approximately 4 lbs less draw weight compared to many other limbs on the market. Shooting them in barebow, I can definitely say they are faster. Switching from my ux100s with the same specs, My crawl has gone down half an inch while having to turn my tiller bolts out and shorten my draw length by half an inch.

• Stability: Uukha claims the Omega offers torsional stiffness comparable to their Sx+

model, which results in straighter nock travel and tighter groupings. This to me has been the biggest performance gain especially compared to other high-end limbs. Shots feel like they are through a tunnel.  I could really feel that my arrows flying straighter and I could tell any shots that were off horizontally were definitely my fault.

• Smoothness: The U5 profile provides a linear draw effort with a power increase of

approximately 3.5% at the end of the draw, designed to minimize fatigue during long

sessions.  This is where you really feel you’ve a got a pair of Uukhas.  More so than previous models.With the UX100s, you feel that smoothness of the draw and absence of stacking. With the SX and VX lines, you feel a change in the draw force specially at anchor but not the “let off” kind of feel you get from the U5 Omegas.  This is where opinions will split.  I have to admit, the first time I drew these limbs, I was shocked at the feeling.  Using the same tiller settings on my Xceed as when I was using my UX100s, it really felt like there was a let off when you reach about 27 inches. Then on anchor, the “infinite draw” kicks in where you feel like you can draw the bow endlessly. A very unique and at first, jarring experience.  More on how I adapted later.

• Weather Resistance: The Monolith Carbon technology ensures that performance

remains consistent across various temperatures and humidity levels, as the limbs do not

contain wood or foam cores that can be affected by environmental changes.  I did leave my Omegas in my car for 8 hours in the sun.  They didn’t break but I’ll probably never do that again.

• Wind Performance: The streamlined, screwless design reduces the limb's surface area,

which can improve accuracy and sight marks in windy conditions. I find that the torsional rigidity of the limbs plus their sheer speed make these limbs great for windy conditions.  The Omegas are thin and light. Almost comically so.  But I’m guessing that’s where their speed comes from.  Specially on a heavy weight barebow setup, you can’t tell the limbs are on.

Are these limbs as good as they say they are? Yes.  So much so that after only a couple of weeks of tuning and shooting them and specially considering I scored a 345 with my trusty old UX100s, I will use the U5 Omegas in the upcoming 2026 Barebow Asia Championships, a couple of weeks from now. 

Will everyone gain scores by using a pair? No.  These limbs are not for everyone.  Dare I say, majority of archers will not like them at all.  Similar to all Uukha limbs, there is a kind of learning curve when you start using them specially coming from traditionally designed limbs.  The snap of the release is very different.  The draw force curve is different.  And most of all, the feel during anchor and expansion is vastly different. A lot of archers prefer limbs that stack.  This gives them a kind of back wall to get a more consistent draw length off of.  These limbs take a lot of getting used to.  Specially towards the back.

Are these limbs more forgiving than others?  Yes and no.  To preface, forgiveness in archery is margin of error your bow can give before throwing your arrows off by a mile.  The Uukha Omegas are very forgiving horizontally or laterally.  Because of how stable they are, it almost feels you can see a straight line when your arrows follow towards the target.  Shots where I was sure they were 9 o’clock blue/red still end up in 8 or 9. I especially like the feedback I get when my shots are poorly aligned. Because of how straight they cast arrows, you can easily tell and adjust when you are off.  When the arrows a off target sideways, you know you can only blame yourself.  Now in terms of forgiveness on the vertical axis, I think this is the trade off you get when using these limbs.  Because of how fast the limbs are, any slight variation on the draw length greatly affects the your vertical grouping. Compounded by the let off and infinite draw effects these limbs have and it can get difficult getting a consistent draw length and anchor.  On the other hand, these same effects make the limbs easier to aim and lighter on the body so you feel you can shoot more. 

How do they compared to other limbs?

• VS Carbon Wood Limbs – Wiawis MXT XP, Wiawis NS XP, Core Accevia

They are the absolute opposite.  Wood limbs tend to be softer at the start and progressively harder the farther back you draw.  Wood limbs have a lock and load type of feel where you have a noticeable cue of when to shoot because of the stacking. Like hitting a wall.  The Omegas are stiffer at the start and super soft at the back.

• VS  Carbon Foam – Hoyt Axia, Kinetic Vaultage, Kinetic Fury, Kinetic Honoric, Kinetic Astonix

The start of the draw cycle feels more similar comparing Foam limbs to the Omega limbs. The biggest difference between the two is towards the back end, close to the anchor point. With Foam limbs, you get a smooth and gradual increase in draw weight as you anchor and expand. Like a “ready, steady, go!” feeling. The Omegas on the other hand have a sudden, almost jarring, let off feel when you approach anchor. Like the poundage suddenly dropped off.  I suspect, like with other Uukha limbs, the Omegas would be a breeze through the clicker.

• VS Other Uukha limbs – UX100, VX+, Sigma, Evo2

The U5 Omegas are the combination and culmination of previous Uukha designs and iterations.  You can also see a level of temperance in the updated design.  Gone are the radical curves and freakishly tiny limb tips replaced by a more mature, and confident design.  With the Omegas, you get the blistering speed and torsional rigidity of the old UX100s without the aggressive jumpiness.  You get the smooth draw and crazy let off of the more recent generations minus the super aggressive shape of the S Curve design.

Who are the Uukha U5 Omega limbs for?

IF you want the absolute best in speed and lateral forgiveness and you are willing to adapt your process to suit the limb’s unique force curve and feel, you will have a blast with these limbs.  They are easy to aim and hold.  Unlike previous Uukha limbs that want to pull your draw arm in if you hold too long, these limbs give a more laid back, almost Zen feeling. This however is no free pass to be lax with your process. Because of the soft back end, I have found that I have developed a slight creep or collapse in my anchor when I am not paying attention. Probably because my back relaxes because of how soft the bow feels. 

Another thing that I notices while shooting the Omega limbs is that because of how soft they feel, if I don’t focus on keeping a solid bow arm, my arrows drop to 6 o’clock 7 or 6.

Because I have been using Uukha limbs almost exclusively since 2018, upgrading the Omegas make a lot of sense. 

If you are having trouble shooting long distances or struggle in the wind and you can’t shoot very high poundage, Uukha limbs are good, albeit expensive options.

If you are struggling to shoot through a clicker, the Omegas can help.

Older archer like myself who don’t have high endurance levels anymore will benefit from the softer feel.

The Uukha Omega limbs are the pinnacle of monolith carbon construction and design. Uukha has made some bold claims about these limbs and feedback from the community been overwhelmingly positive.  Having shot these for a couple of weeks, I can say all the claims are true.  Which begs the questions, if they are as good as what everyone says, why don’t we see Olympic champions shooting Omegas?  There are very specific kinds of archers who will benefit from these limbs.  Probably no one in Olympic recurve are the highest levels have tried them out for long enough.  I am confident though these limbs will break records and win medals in barebow archery.  I do know one thing, my barebow game has levelled up with these limbs. They give me a level of control and confidence I never had before.

Recommended Setup Tips

● Brace Height: Uukha typically recommends staying within a plus or minus 10mm range of their suggested brace heights. A lower brace height generally favors speed, while a higher one favors stability.  I have played around with the brace height and this claim real!

● Tiller Bolts: Nominal draw weights for Uukha limbs are typically measured at the median

setting of the tiller bolts on a 25" riser.  Different brands measure this differently. If you feel that the “let off” is too jarring, add a full turn or 2 on your tiller bolts. 

● Hoyt String Tension Tech: As with previous Uukha limbs, the soft setting on the Hoyt String Tension setting won’t work due to the shape of the limb’s base. They basically won’t make contact. I find the aggressive setting to work best.  Adding a slight tightness to the super soft back end at anchor.
