Here is the super strong and stunning looking rear strap for the KF and K1 Aero, the Alloy rear strap has the ability to adjust the width and height of the rear link position with ease. With a quick insert of washers under the strap you can change the roll centre height. It comes with the settings of 33.5mm and 42.5mm link width and with no washers under the strap you will have the equivalent height on the carbon strap of 4mm washers on your ball stud.
