Rule 28 Aero Sleeves

Rule 28 Aero Sleeves The Rule 28 Aero Sleeves are a set of fully UCI Legal aerodynamic arm screens. They’ve been designed with road and criterium racing in mind; and really come into their own above 40kph; saving you up to 22.5 watts at 50kph. For reference; in their independent product testing; Rule 28’s tester was 1.91m and 100kg – so savings for smaller riders will be proportionately lower.
