Aren’t they great?! I still have fun on mine, and I love the power and modulation of the Magura Gustav brakes...they’re utterly incredible. Here’s a video on the M1 from last year (although I was taking it easy and not jumping things because of a malfunctioning shoe sole =)

 Mine would look pretty good next to this M-1 stylized M29 =)

 @WRCDH: Sold the frame some years ago, bet frame at that time I think. And the Gustav would still be one of the most powerful brakes today!
