Swix Triac 4.0 Aero is the result of continues research, testing, analyzes, experimental trials and process improvements. Performance and nothing else has been the focus. The new tube has a complete new cross sec - tion giving optimum stiffness properties and reduced windrag. Stiffness is increased with more than 15% versus its predecessor Triac 3.0. Wind tunnel testing confirms up to 20% reduced drag coefficient in critical areas of the tube compared to tubes with a cylindrical cross section. The Swix Triac Aero is 100 % adoptable to the Swix TBS and TCS systems allowing top performance in all possible conditions.
- Stiffness: 21 mm
- Shaft weight: 56 gr/m
- Strength: 70 kp
- Total weight 155 cm pole: 136 grams
**MUST READ!! Please note that the new Swix Triac 3.0 and Quantum 1-3 series poles have redesigned handles with less material above the strap connection. The strap anchor point height (the point in which the strap exits the pole) remains the same for a given marked pole size and therefore should be fitted the same as previous models. If you used a 150 cm before, you would still use a Triac 3.0 or Quantum 1-3 marked as 150 cm. The very top of the pole does not measure quite as tall, however this is not part of the function of the pole and does not require a fit change.**

DISCLAIMER: The above size chart has been developed and refined over many years by Gear West staff, local coaches, and customer feedback from recreational and race skiers. It is based on modern trends in Nordic skiing, however it is not based on any official rules. It is the sole responsibility of the consumer to verify pole length compliance in applicable racing events. Also note that these measurements are based on the entire length of the pole assuming that strap anchor point is slightly below the top of the pole.
