Anyone has a set of these? There seems to be conflicting info about these, with some sources indicating that they are 24mm wide, while others are quoting 28mm.

Has anyone measured theirs?

How is the fit with fat 28c tires (like Conti GP4000s IIs)?

C40 discs come in 2 versions. Tubeless and tubular and they have different width with tubeless being 24mm and tubular 28mm

So they made their clincher version narrower than the tubular? That's unusual... And disappointing...

24mm is indeed a little bit old compared to all other brands going much wider (the craziest is Roval with their 29.4 mm external).

I am intending to get the C60 clinchers.
Anyone knows the external width ? Is it the same than the C40 then?

Yes, same width as C40
