Union Trilogy Bindings Review

Who are the Trilogy  Most Suited To?

The Trilogy are best suited to anyone looking for mid-flexing bindings that strike a good balance between faster riding/carving and slower riding with good agility. And something that across all factors don't show any areas of weakness and provide a good predictable, smooth response. 

Best matched with boards in the 4/10 to 7/10 flex range and particularly good for boards in that 5/10 to 6/10 range. 

The Trilogy  in More Detail

O.k. let’s take a more detailed look at what the Trilogy are capable of.

Demo Info

Bindings: Union Trilogy  2024, Medium

Date: March 20, 2023

Conditions

Overcast to start. But higher cloud. 85-90% visibility. Towards the end of the day there was some rain. 

Temperature was around 2°C (36°F) - and -2°C (19°F) with wind chill in morning and 1°C (34°F) (and -2°C (19°F) with wind) in the afternoon. SE winds morning and afternoon at 10kph (6 mph) morning and 5kph (3 mph) in the afternoon. 

24 hour snow: 0" (0cm)

48 hour snow: 0" (0cm)

7 day snow: 4" (11cm)

On groomer:  Soft packed and bordering on slushy. But not ultra slow or sticky or anything. Got a touch slushier towards the end of the day, but not by much. Was pretty consistent. 

Off groomer: Decent enough. Borderline slushy but not quite. Not ideal but OK.

Set Up

Bindings angles: +12/-9

Stance Width: 530mm (20.9″)

Board demoed with: GNU Klassy

Footbed length: 23.5cm (9.3”) 

Footbed Length Fully Extended: 24.5cm (9.7”) 

Baseplate Length (underside):  22.7cm (8.9")

Highback Height: 19.5cm (7.7”)

Weight: 980 grams (2lb, 3oz)

* for one binding, including screws and disc. The average weight of a small sample size of women's bindings that we've weighed (2020, 2021, 2022, 2023 & 2024 models) is 825 grams (1lb 13oz). So the Trilogy was heavier than average on the scales, but felt normal on snow. 

Tester: Meira

Rider Height:  5'4 (163cm)

Rider Weight: 130lbs (58kg)

Rider Boot Size: US Women's 8 (Burton Limelite)

Control Bindings: Union Milan

Flex

The Trilogy felt very middle-of-the-road in its overall flex. Nothing too stiff but not overly soft either. 

Responsiveness

Maneuverability at slower speeds was good. Not quite as good as my control bindings (Union Milan) but when it came to carving they allowed for a deeper carve vs my control bindings. 

Overall they provided a nice smooth response. 

Board Feel/Butterability

Board feel was not as good as it is with my control bindings, but they are very good. A little harder to press with these. But nothing terrible or anything. 

Pop/Ollie Power

Very similar to control bindings, but just a little less. 

Adjustability

Heel Cup: Yes!

Stance Width: Can run disc horizontal and that allows micro stance width adjustments.  

Highback Lean: Yes and tool-less.

Ankle Strap Position: No.

Toe Strap Position: Yes - 2 position options – you’ve got to kind of unclip the plastic bit at the bottom of the baseplate to change positions but it’s not too hard.

Ankle and toe strap length: Tool-less.

Gas pedal/toe ramp extension: Yes

Highback Rotation: Yes - 2 position options.

Compatible with: 2 x 4 | 4 x 4 | The Channel

Shock Absorption

Good amount of padding (2.3cm angling down to 2.1cm at heel (canted) and 2.6cm down to 2.4cm on toe end) and nice cush/springy feel to it. Also has a new "Molecular Bushing Suspension System" which may also help with shock absorption. 

On snow they did a really good job of absorbing shock on landings and chatter. 

Comfort

Overall didn't notice any discomfort from pressure points or anything like that, really comfortable. 

Ankle Strap: Felt good and no pressure points.

Toe Strap: Ditto ankle strap. 

Canted Footbed: Yes

Padded Footbed: Good padding (see shock absorption section above) 

Highback: Good bit of padding and flex to the highback - and no calf-bite when testing on snow.

Ankle Support

It's not top of the line, but it's pretty good. There are no ankle strap position options, it is where it is. So you can't put it higher up the ankle if you're wanting more ankle support or anything like that, but I liked it in the position it's in. 

Entry/Exit

Good ratchet smoothness and no issues getting in or out of them. 

Score Breakdown and Final Verdict

Check out the breakdown of the score in the table below.

The Trilogy are solid bindings that scored well across all the factors we test for. 

They've had an overhaul for the 2024 model and overall we like the changes. They're not quite as good for higher speed carves compared to what they used to be, but they've improved in terms of agility at slower speeds and have increased their ability to absorb shock.
