Are you searching for the freshest Kink Eagle bars review to see if it fits you?
Note: From my knowledge, Kink renamed the old Eagle bars to Union bars. At least they are completely identical.
The Union bars are Kink’s first 4-piece handlebar design, offering a modern take on a classic look.
Built from straight gauge 4130 chromoly tubing and put through Kink’s TruTherm post-weld heat treatment, these bars deliver max strength and durability.
If you’re looking for a set of 4-piece BMX bars with a solid, stiff feel, the Kink Union Bars are a great option.
They come in two rise options (9” and 9.5”), both with a comfortable 29.5” width and a 12° backsweep with a 1° upsweep.
I’ve seen many dudes who ride these out of the box.
But then there are those who cut the bar to somewhere around 28″ (my favorite bar width).
This review covers:
Kink Union (ex Eagle) 4pc Bars Review
1. Kink Union Bar Design & Build Quality
The Kink Union bars feature strong, straight-gauge 4130 chromoly tubing.
This ensures durability, but at the same time, you can expect these to be slightly heavier compared to butted chromoly bars.
In my case, if the same bar is available as butted and as a straight gauge version (like Shadow’s Vultus is), I always opt for the straight gauge.
It’s just more hardcore.
Also, because Union bars use straight gauge tubing, the price is lower. However, I still think they are just slightly pricey for a straight gauge four pice bar.
The TruTherm heat treatment enhances the strength of the welds, giving these bars extra toughness to handle heavy riding.
Moreover, the 4-piece construction is designed for stiffness and durability, making them a solid choice for aggressive shredders.
In short, these bars are ready for just about anything and anyone.
Go big, go tech, the Union bars don’t care – they handle it all.
2. Kink Union Handlebar Key Features
- Straight gauge 4130 chromoly construction: Provides durability and strength.
- TruTherm post-weld heat treatment: Increases longevity and resistance to stress.
- 4-piece design: Offers a unique, stiff, and responsive feel.
- Available in two rise options (9” and 9.5”): Choose based on personal preference.
- Comfortable 29.5” width: A great all-around width, but feel free to cut the bar to any width you prefer.
- 12° backsweep & 1° upsweep: Designed for a more natural wrist position and comfort.
3. How Kink Union BMX Bars Ride
The Kink Union bars feel strong and stiff.
They are ideal for riders who prefer a more rigid and controlled handlebar setup.
The 4-piece construction minimizes flex, ensuring precise handling for technical tricks and big transitions.
However, not everyone prefers the lack of flex – I think it feels nice, but I’ve never done any really massive drops with a four-piece handlebar.
At 29.5” wide, these bars provide plenty of leverage, while the 12° backsweep and 1° upsweep create a comfortable hand position for extended riding sessions.
If you like 4-piece bars for their stiffness and classic aesthetic, the Kink Union bars deliver a balanced mix of modern geometry and traditional strength.

6. Kink Union Bars Cons
- They’re heavy. About 37.7 oz (9″) or 38.5 oz (9.5″), so they’re not the pick if you’re trying to keep the front end light.
- Straight-gauge tubing = more weight. Strong, sure, but not as weight-friendly as butted bars. However, I do like straight gauge bars a lot – I just trust them more!
- Rise options are limited. Just 9″ or 9.5″, so if you want something shorter or taller, you’re looking elsewhere.
- Chrome usually costs more. Looks sick, but you pay extra for the finish, and that’s expected.
Conclusion: Should You Get The Kink Union Bars?
If you’re looking for tough, well-made 4-piece handlebars, the Kink Union bars are a solid choice.
Thanks to TruTherm heat-treated chromoly tubing and a rigid 4-piece design, these bars deliver strength, control, and long-term durability for BMX riders.
Whether you’re hitting big transitions, sending gaps, or riding technical lines, they provide a stable and secure feel.
Streets, parks, trails, you can do it all with these.
They are a bit heavier than some 2-piece bars, but their added weight increases their stiffness and durability.
These are an excellent investment if you appreciate the classic 4-piece look and want a bar that can handle serious riding.
Perfect for riders who want a long-lasting, stylish, and highly durable handlebar option.
