Max Schaaf runs 4q conditioning out of oakland california. Max is a pro skate boarder, gnarly painter, and excellent bike builder. This dude has built so many killer bikes but the blue knuckle above is one of my favorites, my other is the black 4q knuckle with the twisted pipes. The best thing about Max's bikes is that they get ridden! He's made multiple trips across the country on his bikes. Go check out 4q you won't be disappointed.
