Ah I was thinking "mud flap" which goes on the end of the fender. Had forgotten what we call fenders others call mud guards.
Anyway my guess is they won't be a factory fit but could probably be tweaked to fit. I've put Nirve fenders on a non Nirve bike. I recall the center mounting hole on the rear didn't line up so I had to drill another one. Can't recall what else I had to do.
I suppose the biggest "if" is if they will fit between the fork and seat stays.
