kunstform Picks from the BMX Bottom Brackets category
Our history with BMX parts did not start when we opened kunstform in 2003: some of the team have been riding longer than the shop has existed, and most of us are still on a bike today. So we know pretty well which parts we can trust. A kunstform Pick therefore only goes to what we would bolt onto our own bikes: parts where the quality and the value are right, and that you will enjoy for a long time.
