This adapter allows you to run two cables from a single BMX style brake lever. It uses two lengths of 1.2mm gear-shift cable which split to each brake. You can adjust the point at which each brake engages independently, using the adjustment at the caliper. Designed for a 'Tektro RL570' brake lever but should be compatible with any lever that uses the cylindrical swage end of a standard 1.5 brake cable. Not currently compatible with the MTB style cables that have a different cable connection.
in Version 2 I've reduced the volume by 30% overall, making it cheaper for you!
