Made from high-quality 6061 aluminum alloy using CNC forging technology, these brakes are both incredibly lightweight (just 167g per pair) and seriously durable. The 110mm arm length is perfect for most folding bikes, and the 45mm adjustable distance means you can fine-tune them to fit your specific wheel size perfectly.
