Maybe the exalith 2 brake tracks, think the original exalith wheels were earlier poss around 2011, they had curved lines and were unidirectional I think, the exalith 2 have straight lines.
Amazing braking performance on them even when wet, but I chewed through the first set of pads or so.
Yep Ksyrium SLE’s. From2015. I think they were some of the first to have a exalith brake track. Solid wheels
