Well I sold my tramonts to a kiddy with a 6n 16v, stock 256mm brakes. He wanted to come try them, I told him they probably wouldn't fit. When he turned up, they did. Can't remember offset or width, but I had them to go on an early polo.
The delta mics I'm selling have the bolts backwards and the allen head recessed for maximum clearance, would be surprised if they didn't clear a set also.
