The Speedlock is a quick connector for Formula brakes - you can connect it at the lever, inline or at the banjo bolt at the caliper. You simple pull the cam back and pull apart the cable - it's not alien technology, we've seen it down in hyper competitive motorsport applications.
It's great if you have a break away bike, internal brake lines or even for maintenance.
Optional upgrade to fit any Formula Cura2 or Cura4 brake
