I just put together a new video for the heel lock down showing more details. Check it out.
In our endless journey to make splitboard equipment the best it can be, Karakoram will be releasing a new heel lock down system for 2012-13. The heel lock down will be compatible with all Karakoram Splitboard Bindings (Split30, SL and Prime) starting from 2010. The purpose of the heel lock down is to allow splitboarders to skate more efficiently on flat terrain, and traverse and side step without skins on in tour mode.
The Karakoram Heel Lock Down will be available for upgrades to your current Split30 or Split30SL set up in Fall 2012.
