Some older Flow bindings do not to come with Channel disks, like the Alpha, Haylo, Five and Minx models, as well as models which preceded the creation of the Channel-M6 system in 2010. For those models, Flow has an aftermarket Channel Kit which comes with mounting hardware for all 2010 to current year Channel-M6 snowboards. Please note that sliders/inserts are NOT supplied with the Channel-M6 Kit. Inserts are available from the manufacturer of the snowboard. Please also note that Flow Multi-disks and Flow Channel-M6 aftermarket kits are NOT compatible with the older Channel system with pin-sliders, from prior to the 2010 update to the M6-sliders/inserts.
