The V2 Aero roller skis are the most versatile roller skis available. The large-diameter pneumatic wheels can be used on surfaces where it’s impossible to roller ski on smaller-diameter solid wheels. The skis can be used on dirt roads, limestone bicycle paths, chip-seal pavement and grass. On normal pavement, the pneumatic tires provide an extremely smooth ride.
Many users consider the Aero safer as they will roll over debris that can stop smaller wheels. Another major benefit is that the Speed Reducers on pneumatic tires are much more effective than when used on solid rubber wheels. Because the Speed Reducers are so effective on the Aero the skis have become popular in very hilly or mountainous terrain.
The original Aero with the 150mm pneumatic wheels can cover terrain impossible with any other roller ski. The large 150mm pneumatic wheels easily roll over road debris and provide a very smooth ride. Despite the large wheel size the XL150S is very light at only 2000g per pair, which is why so many say the XL150S is their favorite roller ski.
