Part one of this series looked at the Vision Metron 81, a wheel with better cross wind handling than any 81mm we had ever tested. For part two we turn our attention to Austria and Xentis. The engineers at Xentis have a serious performance background. Their parent company makes exhaust systems for Porsche, Mercedes and even Moto GP teams, so it’s no surprise their wheel sets are cutting edge, despite the lack of name recognition. The Squad 4.2 tubulars are 42mm deep and 22mm wide at the their widest. While this width is dwarfed by some other rims, Xentis uses a unique wave shaped turbulator just below the brake track. This breaks the airflow early to, rather counter intuitively, help the air remain attached at the rim’s interior diameter and remove the negative pressure at its trailing edge. At only 1216grams the rims boast great acceleration for the climber or punchy roller, but a big sprinter and high-speed descender will want to trade up to the Squad 5.8.
Need to Know: Xentis wheels require no special carbon brake pads yet still provide quiet braking on par with other carbon rims. Each rim has a sensor magnetic embedded in the carbon, a rubber grommet to stop valve rattle and is signed by the technician responsible for final QC.
