280g as advertised, but heaver than the 27mm ENVE SES tyres I have on atm (245g).
Marketing talk: Specially designed aero cavities in the patented tread pattern function as vortex generators, creating turbulent airflow on the surface that enables the air to stick to the rim shape of the front wheel. The result is a maximization of the sailing effect by delaying the flow separation from the rim, resulting in the ultimate aero wheel tire system.
I was just looking to get some wider tyres, especially for the rear as I’d like to close the gap between the rear tyre and the seattube. I was looking at some 32mm Conti GP5000’s as they seem to be arguably the world’s most loved and used tyre right now, but then I came across these Continental AERO 111’s so I thought I’d get one for the front (29mm) and will stick a 32mm Grand Prix 5000 S TR on the rear.
