Lightweight rear mudguard

No it will not fit I'm told that the chainguard cut out on the jubilee is larger so the Dommi guard will foul your chainguard, or you will need to modify the Dommi guard to fit.

Bev:

I'm confused: your first question is about whether a Dominator rear mudguard will fit a Navigator but you posted a photo of a Jubilee?

What do you have? A Navigator or a Jubilee?
