Although limited in boot compatibility*, the TR-2 binding is not limited in features and performance. Ski Trab developed a unique heel design that uses downward pressure to maximize steering precision. It also lets you change from ski-mode to walk-mode without exiting the binding; just press down with your pole. At the toe, the wings can open to the side, enabling a twisting release like an alpine binding. These highlights combine to make the Trab TR-2 one of the more interesting ski-touring bindings on the market.
The TR-2 binding has two models with different release value ranges: 5-11 for most skiers and 7-13 for heavy/aggressive skiers with shorter feet. Brake widths available are 88mm, 104mm, and 115mm. The detailed feature list is lengthy:
Downward heel pressure gives a stable, locked-in feeling while skiing.
75mm wide base plates help transfer power to the edges of the ski.
Lateral release at the toe reduces twisting-release forces on your tibia.
Brakes are included and replaceable if you decide to change skis.
Lock lever at the toe offers a fully-locked uphill mode for climbing.
Ability to change modes without exiting the binding is a huge plus.
Fully adjustable release values can be dialed for your size and ability.
30mm BSL adjustment in the heel lets you adapt to different boots.
Two riser positions in addition to flat mode give skin track options.
Short binding plates enable a natural ski flex, improving ski control.
Flatter ramp angle than comparables which reduces quad strain.
Leash attachment point at the toe gives a backup ski-catch option.
Included crampon attachment lets you climb supportable crusts.
* Please note this binding is compatible only with La Sportiva Spectre 2.0, Spitfire 2.0, Sideral 2.0, Starlet 2.0, and SCARPA Spirit boots.
Just out of curiosity, there was a casual mention somewhere in the discussion groups that the Ski Trab factory in Italy can modify any touring boot to be compatible with the TR2 bindings (it appears that in this day and age installing additional metal fittings into the back of the sole should not constitute an engineering problem). Is that true? If so, can it be done at other locations/shops? Thanks
We are not aware of it. The metal fittings are molded in the boot.
I am shopping for touring bindings to connect La Sportiva Spitfire 2.0 with Voile V6 skis to ski in Sierra (Tahoe region). Having read some initial discussion about the TR2, I am tempted to get and install these on my setup, however, I haven't been able to find good analysis of the pros and cons of regular tech bindings vs. the TR2. Is there anything that should give me a second thought before purchasing these? The Voile V6 skis are a bit on the heavier and wider side, but I would be using this setup on Sierra cement so perhaps that weight would be an asset. Also, I wonder if the TR2 binding is more oriented towards racing.
Hi Dmitry, these are not oriented towards race skis; Trab has a whole line of Titan bindings for those. The TR-2 is an full featured touring binding, with exceptional release characteristics. It's one of the rare lateral-toe release tech bindings which means it's more tibia-friendly. In that small category, it consistently performs the best in our release testing. Folks also like that you can switch modes without exiting the binding. The only downside is boot compatibility which is not a problem with your Spitfires.
Hi, your specs say that the touring mode has a flat walk mode and 2 riser levels, but I think it actually just has a semi-flat walk mode with a single riser.
Hi James, The walk mode is very close to flat because the toe piece with pins sits up higher. With that being said, the boot will not lie flush against the ski like some other tech bindings. I've updated the specs to just read "2". Hope this helps, thanks for pointing this out.
Would it be possible to mate the Trab TR 2 toe piece with the ATK Haute Route heel piece to lighten up the rig/work around the boot compatibility issues while maintaining the alpine binding-like releasability?
Retains and releases just like an alpine binding. & tech tours. If not for the limited (but expanding) boot compatibility, I feel like this binding would become the tech 2.0 sensation. I use a Sideral 2.0 and plan to get a Spectre 2.0 at the end of this season. I love these bindings.
I guess the short answer is that it is more difficult to enter the toe. In certain situations it is probably easier than a dynafit, like deep snow on flatter terrain. Steep sidehills can be challenging as you have to push down on your ski to hold the jaws open. The heel is much easier to enter and exit in general and provides an alpine quality retention and elasticity.
