Approved features are preserved. The negative Forward Lean brings advantages when ascending. There is an "ON-OFF" button for the 90° rotating Forwardlean with which you can quickly switch from the efficient "Tourlean" to your favor "Ridinglean". The side walls of the heelcup are higher to give you more edge hold and stability while climbing and also the power transmission is improved. The heel lockdown is also remained.
The Karakoram Prime system is slimmer and lighter than ever, the binding is now easier to install and more pleasant to handle.
New is the Power Link, with which you can easily mount and unmount the binding.
