The Sintesi is lightweight mountaineering ski with a long-ish radius that has great handling on steep ice. It also handles the variable conditions your throw at it due to the Attivo progressive shape and flex. The Sintesi is offered with a couple stiffness ratings, with the "70" being more appropriate for bigger skiers or for carrying a heavy pack. The extra stiffness versus the "60" is due to a Power Fiber wrap around the core. Turns are easy to initiate in a pinch and the rebound is ample due to a light wood core. As per usual with Ski Trab, the skis are finished to perfection with a textured base and sharpened steel edges. The Sintesi is built in Italy and is covered by Trab’s unbeatable 3 year warranty. Let’s just say it’s not their first ski.
- Liwood core is carved with air channels to reduce weight with minimal loss of strength.
- Power Fiber Box Core wrap in the 70-flex is a souped-up carbon cage that is built around the core.
- Fiber Box Core wrap in the 60-flex is a different carbon weave that makes the ski more supple.
- Additional quadraxial and fiber glass layers reinforce the mounting area and add rigidity.
- Robust 52 HRC steel edges are about as hard as you can find on a ski.
- Attivo progressive shape is integrated with the flex for easy variable skiing.
- Sintered bases will take some abuse and come intricately textured.
- Nylon topsheets resist nicks and other damage you’ll try to inflict.
- Made in Bormio, Italy and backed by a three year warranty.
Update 2018/19: Just a new topsheet, otherwise the ski remains the same.

Questions & Reviews
I'm happy with the length as I'll also use these for casual racing, but I would certainly feel comfortable on the 178 as well. I also would not hesitate to buy a new pair of Trab skis having been on these, everything about them feels dialed in and polished.
