I’ve been using Ksyrium Exalith rims for almost 3 years now during winter. The rear has just lost its ‘ridged’ brake track, front still going strong. I think with a normal set of Ali rims I’d have gone through a couple of pairs at this point.
Same here, about 3 years also. Rear brake track is 80% back to alloy both sides. Worn through the exalith coating, looks a bit odd but i'm not to precious about it.
Front still looks like new.
Lovely setup! Aren't you afraid of prematurely ruining the Oxic treatment on the rims riding through the winter slop?
