I like it! I have to get myself a mixte. If I ever come across a Batavus mixte, or any Batavus for that matter, there's no doubt I'll be going home with it.
Batavus just returned my latest email. Good news is I'm now 99.9% sure my Competition is a 1985, as that was the last year for that model until 1989. Bad news is that they don't have component specs for it. Additionally, this is the second time they didn't respond to my offer to purchase catalogues or brochures.
