Odyssey K-Shield linear slic kable. Tried and true pre-stretched 1.5mm inner wire with Teflon coating.
This is the original BMX linear cable. Launched in 2003. Odyssey's proven Slic Kable wire is surrounded by a compression-less housing to prevent the cable from binding when the cable is twisted around during barspin or tailwhip tricks. Special volcano end ferrules to prevent housing blowout have been included since 2008. Ideal for rear brakes.
Fits pretty much all BMX brake levers and brakes
