The R-Style is available on G-10 plate only.
There is no release mechanism at the rear, the rear shell is screwed onto the carbon plate with 2 large T nuts.
On the R-style, the rear shell has no upper cuff. The ankle buckle is moved forward to allow to the foot to release easily when the front shell releases.
Thanks to the many holes drilled on the plate, all angles and distances between the 2 ankles can be easily adjusted.
