The Kizer Soulframes are a unibody design that combines the frame with the soulplate. This allows for a lower, lighter setup that is compatible with a wide range of boots (with flat bottoms) to skate either flat or anti-rocker.
Updated with a shallow groove that protects the middle wheels from sticking when grinding. The frame walls too were improved, providing better protection to all wheels. If skating flat (all wheels the same size), they allow for up to 61mm.
The Kizer Shift Unlimited Superfluid UFS Frames are an entirely new frame concept. Flat, freestyle, or anti-rocker all have their benefits. The Unlimited consists of a single frame skeleton that fits 3 different blocks (included) to skate your best on the streets, at the park, or in the bowl (flat, freestyle, or anti-rocker).
